FAQs

150mm wheels run faster surface speeds, are more responsive to small movements, and suit precision tool sharpening (chisels, plane irons, drill bits). 200mm and 250mm wheels have longer arc-length for grinding, better for general fabrication work — dressing welds, removing material, deburring large workpieces. Many trade workshops have both: a 150mm grinder dedicated to tool sharpening with high-quality fine wheels, and a 200mm grinder for general fabrication.

Aluminium-oxide (the most common grinding wheel material — usually grey or pinkish) is the standard for steel, alloy steel, and ferrous metals. White-aluminium-oxide is a finer-grade variant for high-speed steel and tool sharpening. Silicon-carbide (typically green) is used for non-ferrous metals (aluminium, copper, brass) and tungsten-carbide tooling — aluminium-oxide loads quickly when grinding non-ferrous, while silicon-carbide cuts cleanly. Match the wheel to the material — using the wrong wheel reduces tool life and grinds poorly.

Wheel-dressing keeps the wheel face true (round) and unloaded (clean of embedded swarf and rounded grit). Use a star-wheel dresser or a single-point diamond dresser, pressed against the rotating wheel for several seconds with light pressure — the dresser exposes fresh grit and trues the wheel face. Dress the wheel whenever cuts feel slow or the face becomes glazed or out of round. Star-wheel dressers are inexpensive and last for many sessions; diamond dressers are more precise and longer-lasting.

Yes. Replacement wheels (aluminium-oxide, white-aluminium-oxide, silicon-carbide, wire wheels, buffing wheels) across the standard diameters and bores are available for the majority of Draper, SIP, and Sealey bench grinders. Replacement tool rests, eye-shield assemblies, motor brushes, and switches are also available for common machine models. Match by machine model code and wheel diameter.

Metal Bench Grinder

FilterFilters
View as Grid List

Within Metal Working, Metal Bench Grinder covers the bench-mounted twin-wheel grinders used for sharpening tools, dressing welds, deburring metal edges, shaping small components, and general fabrication finishing work. A bench grinder mounts a motor with a grinding wheel on each end of the spindle — typically one coarse (for fast material removal) and one fine (for finishing and sharpening). Both wheels run continuously when the unit is powered.

Parts For Machines supplies bench grinders across the trade and professional ranges — typical wheel diameters from 150mm (compact bench-mounted) up to 200mm and 250mm (heavier industrial), with motor power scaling accordingly. Parts For Machines is an Authorised Distributor and Seller of Draper, SIP, and Sealey across the bench grinder range. For pneumatic-powered grinding — air-driven die grinders and angle grinders used in fabrication and tyre-bay applications — Parts For Machines offers Chicago Pneumatic (separate sub-category within Power Tools).

Product pages list wheel diameter, wheel width, motor power (typically 0.25-0.6 kW for trade-grade bench grinders), spindle speed (typical 2800-3000 RPM for AC-mains grinders), bore size (the centre hole of the wheels, usually 12.7mm or 16mm), and the type of wheels supplied (a coarse-and-fine pair is standard; some grinders ship with one wheel and one buffing wheel). For tool sharpening, look for grinders with adjustable tool rests and clear wheel guards.

Bench grinder wheels are consumable — replacement aluminium-oxide wheels for general steel work, white-aluminium-oxide for high-speed steel and tool sharpening, silicon-carbide wheels for non-ferrous metals and carbide tools, and wire wheels for cleaning and rust removal are available across the standard wheel diameters. Bench grinders are professional kit. Trade pricing on multi-tool orders is available; contact the team via WhatsApp 07754288583.
