Sharpening & dressing
A bench grinder is bought for sharpening and ends up doing everything: dressing welds, deburring, shaping. We compare runout, tool rest rigidity and speed — and we say plainly which machines ship with wheels worth keeping, because most do not.
200 mm (7.87 in) wheels · 400 W peak · swivelling LED · €93
The step up to 200 mm (7.87 in) wheels, which grind flatter and stay cool longer than 150 mm (5.91 in) ones.
Best for: Sharpening and shaping where a flat, cool grind matters more than portability
≈ $300
250 W · 2,980 rpm · 36 and 60 grit wheels · €40
Forty dollars, and the two wheels it arrives with are the first thing you should plan to replace.
Best for: Deburring, dressing bolt ends and rough shaping — not sharpening chisels
350 W (S6) · brush wheel included · €66
A wire brush wheel on one side, which turns the machine into the fastest way to take rust off small parts.
Best for: Restoration and repair work where everything arrives rusty
≈ $200
150 mm (5.91 in) wheels · deburring, derusting, resharpening · €46
The plain version of a machine sold in three sizes — buy it knowing what the extra €20 adds.
Best for: An occasional bench grinder where the price is the deciding factor
≈ $160
400 W · cast iron base · LED work lights · €72
A grey cast iron base and lights over both wheels — mass and visibility, which is most of what a bench grinder needs.
Best for: A permanent bench installation, bolted down and used for both shaping and sharpening
≈ $190
Wet 200 mm (7.87 in) + dry 150 mm (5.91 in) · stainless tank · 250 W · €122
A wet wheel running through water, which is the only way to sharpen a thin edge without risking the temper.
Best for: Sharpening chisels, plane irons, turning tools and knives without blueing them
600 W induction motor · 200 mm (7.87 in) · 3,600 rpm · €208
An induction motor and sealed bearings in a die-cast housing — the machine built to run rather than to be bought.
Best for: Daily workshop use, where the machine runs every day and nobody wants to think about it
Power decides the ability to hold speed when you press. A grinder that slows heats the work without machining it.
For sharpening tools, finesse and control count more than brute force. A moderate machine is amply enough.
An unbolted grinder shifts at the first push and brings the tool back towards the hand. Drilled feet and a wide base are what let you bolt it down once and for all.
It has overheated and lost its temper: the edge will no longer hold. Quench often in water and do not press.
Imperatively, a few millimeters from the wheel at most. A larger gap lets the workpiece jam between the rest and the wheel.
With a diamond or a dressing wheel, as soon as the surface becomes irregular or glazed. A dressed wheel cuts like a new one.
Not with an ordinary wheel, which slides over it. A specific diamond wheel is needed.
They stop spatter directed at the face. They do not replace goggles or a face shield.
Always, bolted to the bench. A grinder that shifts under load is uncontrollable.
By suspending it and tapping it lightly: a sound wheel rings clear, a cracked one gives a dull note. A cracked wheel shatters in use.
A coarse grit for rough work, a fine grit for sharpening. Many grinders come with two wheels for that reason.
A tool that turns blue has lost its temper: quench often and never press. Set the tool rest a few millimeters from the wheel, bolt the grinder to the bench, and ring-test a wheel before fitting it — a cracked wheel shatters.
Four sets in five must state the figure before a column appears. A half-empty column manufactures false gaps.
