Radius Master Small Wheels

Contact wheels are the heart of the Radius Master system. Each diameter produces a distinctly different grinding profile — from the sharp, tight inside radius of the 19mm wheel through to the broad, gentle sweep of the 50mm. Having the right wheel for the job means the difference between a grinding pass that takes seconds and one that requires multiple compromises with the wrong profile.

These small wheels are 50mm wide, matching the 50 x 1220mm (2″ x 48″) belt used by the Radius Master and Blade Master machines. All wheels feature a smooth rubber surface for consistent belt contact and clean, controlled grinding across the full belt width.

What’s included varies by size:

19mm, 22mm, 25mm, 32mm, and 38mm wheels — supplied complete with bearings and mounting screws, ready to install directly onto the machine’s contact wheel spindle.
44mm wheel — contact NIROC to confirm inclusions.
50mm wheel — supplied with the shaft included, as this size mounts differently to the smaller wheels.

Each size opens up specific grinding capabilities:

19mm — extreme tight radius work; finger choils, deep narrow grooves, fine detail on jewellery and instrument work. Variable speed grinders only at medium-low speed; monitor bearing temperatures.
22mm — tight radius choils and inside curves with slightly more belt surface contact than the 19mm.
25mm — the smallest wheel in the standard RM-48 kit; a versatile tight-radius option for knife choils, fuller entry points, and precision notch work.
32mm — mid-small radius; useful for moderate inside curves, guard fit-up, and handle shaping.
38mm — approaching mid-range; good for fuller grinding, sweep blending, and larger choil work.
44mm — larger small wheel; smooth sweep grinding on blades and curved stock.
50mm — a full 2″ diameter contact wheel; popular in the Three-Wheel Cluster assembly and as a standalone grinding station for medium-radius hollow grinds and profiling.

These wheels are fully compatible with the Three-Wheel Cluster Upgrade Kit — if you own a cluster, individual small wheels are available as replacements when a wheel in your cluster is worn.

Further Information

Choosing the Right Size

If you are replacing a worn wheel, match the diameter of your existing wheel. If you are adding a new size to your setup, consider where the gaps are in your current contact wheel range. The standard RM-48 kit includes 25mm, 38mm, 44mm, 50mm, and 88mm wheels — meaning 19mm and 22mm are the sizes most commonly added by knifemakers seeking tighter radius capability for choil and detail work.

Variable Speed Note for Very Small Wheels

The 19mm and 22mm wheels spin at significantly higher RPM than larger wheels for any given belt speed, which increases bearing load and heat generation. These very small wheels are best used with a variable speed machine (RM48AE-VS) at medium to low belt speeds. Monitor bearing temperatures when first using these wheels in your workflow, particularly during extended grinding sessions.

Compatibility with Three-Wheel Cluster

If you own the Radius Master Three-Wheel Cluster Upgrade Kit, individual wheels from this range can be used as cluster replacement wheels when one of the cluster wheels becomes worn or damaged — extending the service life of your cluster assembly.

Radius Master 8″ Drive Wheel – New Style

The 8″ / 203mm drive wheel sits at the base of the Radius Master belt head and serves a dual role: it is both the primary drive wheel that propels the abrasive belt and a large-diameter contact wheel that provides one of the machine’s seven grinding stations. Work supported against this wheel produces a subtle hollow grind profile ideal for blade bevels, large-radius inside curves, and fast stock removal on flat bar.

The “New Style” designation refers to the current-production design used on Series 2 machines — an updated geometry and rubber compound that improves belt grip, tracking stability, and durability over extended use. If your machine is a current Series 2 model (RM-48 or RM48AE-VS), this is the correct wheel. For older-style machines, see the Old Style Drive Wheel listing.

Over time, drive wheels can develop:

Surface glazing — hardened rubber that loses grip on the belt backing, causing slippage
Flat spots — from sitting under tension when the machine is stored for extended periods
Uneven wear — particularly on one side if belt tracking has been running consistently off-centre
Rubber cracking or separation — from age, solvent exposure, or heat buildup in heavy use

Any of these conditions reduces belt drive efficiency, affects surface finish quality, and can cause unpredictable belt tracking. Replacing a worn drive wheel is one of the most impactful maintenance steps you can take on a Radius Master machine.

This replacement wheel is manufactured by NIROC to the same specification as the factory-fitted wheel, ensuring the correct rubber durometer, diameter tolerance, and shaft bore for a drop-in fit on the Series 2 belt head. No machining or modification is required.

Signs your drive wheel needs replacing:

Belt slipping or surging under load
Difficulty maintaining consistent belt tracking
Vibration or wobble at belt speeds
Visible flat spots, surface cracking, or rubber separation
Uneven contact across the belt width when grinding

Note: If you own an older-style Radius Master (pre-Series 2 or earlier production), check the Old Style Drive Wheel (203mm) listing instead. If unsure which wheel your machine requires, contact NIROC with your machine serial number before ordering.

Further Information

New Style vs. Old Style — Which Do I Need?

NIROC supplies two variants of the 203mm drive wheel to support the full Radius Master install base — New Style for current Series 2 production machines, and Old Style for earlier models. The external dimensions are similar but the bore, keyway, or hub geometry may differ between generations. Always confirm your machine’s production date or serial number with NIROC if you are unsure.

The Drive Wheel as a Grinding Surface

Beyond its drive function, the 8″ contact wheel is one of the most versatile grinding stations on the Radius Master. Its 203mm diameter produces a gentle hollow grind profile on flat stock — preferred by many knifemakers for primary bevel grinding on blade blanks, and by engineers for de-burring and radius blending on larger components. A fresh, true drive wheel also supports precise use of the Drive Wheel Tool Rest (RM-DWTR) and Hollow Grinding Jig (RM-HGJ) accessories.

Proactive Replacement

Even if your current drive wheel hasn’t failed, replacing it as part of a scheduled overhaul every few years is good practice on a heavily used machine. A fresh rubber surface improves belt grip, reduces motor load, and gives you more consistent tracking right out of the gate.

Radius Master Fixture Table & Multi Application Work-rest.

Most belt grinder accessories are purpose-built for a single task. The Radius Master Multi Table is different — it’s a multi-application platform designed to support workpieces, mount fixtures, and provide stable grinding references across several stations on the RM-48. The result is a single accessory that earns its place in the workshop by solving multiple problems at once.

The Multi Table mounts to the Radius Master frame and provides a flat, rigid work surface that can be positioned and locked at the angle and height required for your task. Its broad surface area supports longer workpieces — full-length knife blanks, bar stock, and plate — that would otherwise be unsupported during grinding. It also serves as a mounting platform for jigs and fixtures, making it valuable for production knife makers, toolmakers, and anyone who needs to repeat the same grinding operation accurately across multiple parts.

As a workrest, the Multi Table keeps your workpiece at a consistent height and angle relative to the belt, reducing the hand fatigue and technique variation that comes from freehand grinding over extended sessions. For users who find themselves spending time compensating for workpiece drift or re-establishing grinding angles pass after pass, a solid mechanical reference surface like the Multi Table is a significant upgrade in consistency and efficiency.

Key uses include:

Supporting full-length knife blanks during primary bevel grinding
Providing a flat reference surface for flat-grind geometry
Mounting custom jigs and fixtures for repeatable production work
Supporting bar stock and plate during surface finishing and de-burring
Workrest for extended grinding sessions to reduce fatigue and improve consistency
Multi-position setup for sequential operations without repositioning the workpiece

Why a Fixture Table Changes Your Workflow

There’s a clear difference between grinding freehand and grinding with mechanical support. Freehand technique is flexible and valuable, but for operations that need to be repeated consistently — same bevel angle, same grind height, same finish quality on every blade — mechanical support is what makes the difference between a good craftsperson and a consistent production operation.

The Multi Table gives you that mechanical support without locking you into a single application. By adapting to different positions and configurations, it supports the variety of work that a typical RM-48 owner actually does: sometimes flat grinding, sometimes supporting long blades at the contact wheel, sometimes running a jig for a specific profile.

For Production Knifemakers

If you’re making more than a handful of knives at a time, consistency between pieces is critical — for quality, for reputation, and for your own efficiency. A fixture table that holds your blade at a set height and angle means the 20th bevel of the day looks like the first, regardless of fatigue. The Multi Table is the practical answer to this problem on the Radius Master platform.

Combining with Other Accessories

The Multi Table works independently but pairs particularly well with the Hollow Grinding Jig (RM-HGJ) for blade support during hollow grinding, and with the Platen Table (PT-48) for flat grinding workflows. If you’re building out a complete production setup on the RM-48, the Multi Table is a foundational piece of that system.
