Powering Hundreds of Businesses Including:

Most grinders try to do too much, resulting in a compromise that eventually shows up in your portafilter. The Macap M42M is built with an espresso-specific focus for those who have moved past multi-purpose equipment and want a build quality that reflects a serious investment in their setup. This Macap Model ID represents a lineage of Venetian engineering where the priority is mechanical consistency rather than unnecessary digital distractions. It is time to equip your counter with a tool that finally matches the standard of the coffee you’re sourcing.

Product Features

Stepless Micrometric Adjustment

A continuous collar lets you fine-tune grind size with high precision instead of fixed clicks, so dialing in an espresso shot down to fractions of a setting is straightforward.

58mm Flat Steel Burrs

Flat 58mm steel burrs deliver consistent particle distribution for clean, repeatable espresso extraction, with enough range to handle moka pot grinds as well.

On-Demand Timed Dosing

Program single and double shot times or grind manually with a dedicated button. A built-in portafilter fork holds your portafilter in place so you can grind hands-free once it's locked in.

Compact 1.1 lb Hopper

A 1.1 lb hopper keeps the footprint small and is sized for frequent refills, fitting comfortably on a home counter or a low-volume café bar.

Efficient 250W Single-Phase Motor

A quiet 250W single-phase motor is built for short, frequent grinding cycles rather than continuous commercial duty, keeping noise and heat down during everyday use.

Commercial-Grade Build, Home-Ready Footprint

The M42M brings the grind consistency and build quality of a commercial-style grinder into a footprint that fits a serious home setup or small office, making it a solid choice for anyone pulling multiple shots a day.

The Coffeeionado Take

Who's It For:

  • Home Baristas Ready to Step Up — If your current grinder is holding back your espresso, the 58mm flat hardened steel burrs and stepless micrometric adjustment offer the precision to actually taste the difference
  • Intermediate to Advanced Home Users — Those who've outgrown entry-level grinders and want the adjustability and build quality to explore different roast levels and brew methods
  • Italian-Made Purists — Manufactured in Italy with the build quality that implies. For those who value proven engineering pedigree

It's Right For You If:

  • You're looking for a capable home grinder with stepless micrometric adjustment that lets you fine-tune your espresso without the compromises of stepped settings.
  • The stepless micrometric adjustment gives you infinite control over particle size, so you can chase that perfect extraction without being locked into preset steps.

Things to Consider:

  • At 7.3kg, it's light enough to move around but solid enough not to walk across the counter during grinding.
  • No programmable dosing presets — you'll be manually timing or weighing each dose. Some baristas prefer this control; others find it adds a step to the workflow.

Our Take:

The Macap M42M Espresso Grinder is a well-built prosumer grinder with 58mm flat hardened steel burrs that punch above their size class. A solid choice for home baristas who want café-quality espresso without café-sized equipment.

M42M Espresso Grinder by Macap

A customer favorite for its price point and durability, the M42M grinder by Macap is an on-demand grinder with a small footprint. The fingerguard of the bean hopper has been redesigned to help beans flow through easier while still protecting your fingers. The adjustment dial numbers are printed with a light color, which makes it a lot easier to read.

Dual Mode

The M42M can switch between semi-automatic and on-demand grinding. On the right side of the grinder, there are 2 switches. The one on the right is the power switch. The one on the left switches between the 2 modes. The “M” position is for semi-automatic grinding. The “T” position is for on-demand grinding.

Programmable Functionality

To the right of the coffee chute is the programmable adjustment knob. It adjusts the length of time when grinding on demand. Turning clockwise to a lower number will decrease the grinding time. Turning counterclockwise to a higher number will increase the grinding time.

On Demand Dosing

The red button underneath the coffee chute grinding process. When semi-automatic grinding, press and hold until you have the amount of ground coffee desired. When grinding on demand, press once for a single dose or twice for a double dose.

Stepless Grind Adjustments

No matter the size, you will be able to dial your shots in with ease with the stepless adjustments. We suggest this grinder for small to medium volume establishments.

What We'd Tell You In Store

How to Choose a Commercial Espresso Machine

How to choose a commercial espresso machine based on real volume numbers, peak hour output, and drink mix — not vague categories.

How to Choose a Commercial Grinder

Your espresso machine gets all the attention. The grinder does all the work. Every variable that determines shot quality — particle size, extraction evenness, dose consistency — starts at the grinder.

How to Design Your Cafe: Build Your Bar for the Rush

Design your café bar for peak volume, not average traffic. Equipment layout, station design, staffing ratios, and tools that remove steps — what actually matters during the rush.

Setting Up Your Commercial Espresso Machine Right

Water pressure, electrical specs, drain slope, filter flushing — what actually goes into a commercial espresso machine setup, and what gets skipped.

Product FAQ

Is the Macap M42M a stepless grinder, and how precise are the grind adjustments?

Yes, the Macap M42M is a stepless grinder. Instead of fixed ‘clicks,’ it uses a continuous collar adjustment that lets you fine‑tune the grind with high precision, which is ideal for dialing in espresso shots very accurately.

Can the Macap M42M grind for both espresso and filter coffee, or is it espresso‑only?

The Macap M42M is optimized for espresso and excels in that range. It can be adjusted coarser for moka pot and some manual brew methods, but if you frequently switch between espresso and filter, you’ll need to recalibrate your grind setting each time, which can be less convenient than using a dedicated filter grinder.

How often do I need to replace the burrs, and how long do they typically last?

Burr life depends on usage and bean type, but as a general guideline the M42M’s flat burrs can last around 600–800 lbs (270–360 kg) of coffee before you’ll notice a drop in performance. In a typical home setting this can mean many years of use; in a busier environment they may need replacement every 1–3 years. Visual wear and declining shot consistency are good signs it’s time to change them.

What kind of burrs does the Macap M42M use (size, material, and burr type)?

The Macap M42M uses flat, hardened steel burrs. The burrs are designed for espresso‑focused grinding, giving a consistent particle distribution and good clarity in the cup. Exact burr diameter can vary by sub‑model/region, so check the specifications on the product page if you need a precise measurement for comparison.

Is the Macap M42M suitable for home use, or is it better for a small café or restaurant?

The M42M is well‑suited to serious home baristas and low‑volume professional settings like small cafés, coffee carts, or offices. It has the build quality and grind consistency of a commercial‑style grinder, but its size and workflow also make sense on a home countertop for users pulling multiple shots a day.

Will the Macap M42M fit under most kitchen cabinets in the U.S.?

Standard U.S. kitchen cabinets are typically 17–18 inches above the counter. The Macap M42M’s height with hopper is in that general range, but can be tight depending on your cabinet clearance. If space is limited, you may want to use a smaller hopper or measure your counter‑to‑cabinet distance and compare it to the height listed in the product specifications.

Does the Macap M42M offer timed or manual dosing, and can I grind hands‑free?

The Macap M42M is typically available with on‑demand timed dosing, allowing you to program shot times for single and double doses, as well as manual grinding via a dedicated button or switch. It includes a portafilter fork so you can grind directly into the portafilter in a mostly hands‑free manner once it’s locked in place.

How fast does the Macap M42M grind, and can it keep up with multiple drinks in a row?

Grind speed depends on the grind setting and dose size, but for typical espresso doses (around 18–20 g) you can expect it to grind in roughly 8–14 seconds. This is fast enough for regular home use and for light commercial or office service, where it can comfortably keep up with several drinks in a row without overheating.

Do you ship to PO boxes?

No, we don't ship to PO boxes. Due to the size and weight of our equipment, we require delivery to a physical address where our carriers can safely drop off your order.

How does free installation work?

We want to make your purchase as smooth as possible and will pay the installation via rebate on commercial espresso machines. This includes commercial machines with more than 1 group head and 220V.

If the certified installer needed is over 1.5 hours away then we will pay for the installation call (and install up to the value suggested on page minus call fee). Travel will be paid by customer. Inquire if you have any questions about your location.


Please note, any discounts subject to void the paid installation offer.

At Coffeeionado, professional installation is included with qualifying espresso machine purchases. Our goal is to make the process as seamless as possible — from coordinating the technician to getting your machine up and running on day one.

Which Machines Qualify

Free professional installation is included with all espresso machines of 2 groups or more where indicated on the product listing. This policy applies to espresso machines only and does not cover other coffee equipment such as grinders, brewers, or accessories.

If you are unsure whether your machine qualifies, contact us before purchasing and we'll confirm.

What's Included

  • Travel and labor costs for installation within the technician's service area (up to 2 hours of travel)
  • Setup, basic programming, and commissioning of the equipment
  • Scheduling during regular business hours, Monday through Friday
  • Associated taxes and fees related to the installation itself

Installation must be completed within 90 days of delivery of the equipment. The installation benefit lapses after this window and cannot be reinstated.

How Installation Is Arranged

Depending on your purchase, installation is handled one of two ways:

Arranged directly — In many cases, Coffeeionado or the manufacturer will coordinate and pay the technician on your behalf. We will contact you after your order is processed to schedule the visit.

Reimbursement — In some cases, you may be asked to arrange the installation locally using an authorized technician and submit a rebate form for reimbursement. Once approved, the covered amount will be refunded to the original payment method used for your order.

We will confirm which arrangement applies to your purchase at the time of order confirmation. If you have questions before purchasing, contact us and we'll walk you through it.

What's Not Included

The following are outside the scope of the installation policy and remain the customer's responsibility:

  • Travel or callout costs beyond the first 2 hours of the technician's travel time — if your location falls outside the local service area, the overage is the customer's responsibility
  • Water filtration systems and installation materials — including plumbing fittings, tubing, plugs, outlets, and any other ancillary components required to prepare the site
  • Electrical or plumbing work — site preparation must be completed before the technician arrives
  • Training on equipment operation — installation covers commissioning only, not barista or operational training
  • False start or callout fees if the technician arrives and the site is not ready for installation

Important: If a technician arrives and cannot complete the installation because the site is unprepared, you will be responsible for any callout or false start fee charged by the technician. However, your installation benefit remains intact — the visit will be rescheduled at no additional cost to your policy.

Water Filtration Requirement

Water filtration must be installed and operational before or at the time of installation. This is not optional — operating a commercial espresso machine without proper filtration will void the manufacturer's warranty. If filtration is not in place at the time of the technician's visit, installation may need to be rescheduled and the callout fee will be the customer's responsibility.

If you need guidance on water filtration requirements for your machine, contact us before scheduling your installation.

Service Area

Installation coverage is tied to the manufacturer's authorized technician service area, generally within a 1.5-hour radius of the nearest certified technician. If the customer's location falls outside this area, Coffeeionado will make reasonable efforts to arrange a local authorized technician, but travel costs beyond the 2-hour coverage limit remain the customer's responsibility.

Not sure if you're in a service area? Contact us before purchasing and we'll check your location.

What to Expect on Install Day

Getting a commercial espresso machine delivered is one thing. Getting it actually running — plumbed, programmed, and pulling properly — is another. Here's what happens when the technician comes out.

Before the appointment: Site preparation will be confirmed before technicians make it out. Once your machine ships, we'll coordinate scheduling with you and assign a local certified technician. Before they arrive, make sure your space is ready: the machine's permanent location should be determined, your water line and drain access should be in place, and your electrical supply should match the machine's requirements. 

On the day The technician will handle the physical installation of the machine — positioning, water line connection, and drain setup. Once it's plumbed and powered, they'll run through the setup and basic programming: boiler pressure, shot parameters, and confirming that water flows correctly through the group heads and steam wands. Some basic training will be provided, they'll pull test shots to verify the machine is operating within spec.

After Installation

Once your machine is installed, we'll provide referrals for authorized service technicians in your area for ongoing maintenance and repairs. Coffeeionado offers lifetime support on all equipment we sell — we're here long after the install is done.

Governing Terms

This installation policy forms part of your agreement with Coffeeionado and is subject to our Terms of Sale and Terms of Service. In the event of any conflict, the Terms of Service governs.

Can I pick up the machine at your store?

We do not have a showroom or storefront for customer pickups, so orders cannot be picked up directly from us. That said, there is an exception for La Spaziale and La Pavoni products, you can contact us to arrange.

However, if you'd prefer, we can arrange to have your machine shipped to a local freight terminal/location for pickup instead. Let us know your city/state (or ZIP code), and we’d be happy to check the nearest terminal options for you.
