Record Power RSBG8 review

A 200 mm (7.87 in) bench grinder for sharpening tools — at 2,850 rpm, which is the specification you have to work around.

The end of it A capable grinder for reshaping steel. Treat the speed as a constraint on technique, not a feature.

Every figure is a manufacturer specification, read off the listing itself, and the judgments are ours — drawn from how the specification behaves in this class of machine and from what long-term owners consistently report. Where a figure is missing, we say so rather than fill it in.

What the specification says

A bench grinder with two Ø 200 mm (7.87 in) wheels for sharpening metal tools: a 40 mm (1.57 in) wide fine stone and a 25 mm (0.98 in) wide coarse one, on a 16 mm (0.63 in) shaft, turning at 2,850 min⁻¹. The motor is given as 0.55 kW / 0.39 kW. Part number 71551.

Speed is the whole discussion

Grinding is a heat problem. The steel at the very edge of a chisel is thin enough to reach a straw color in a second or two against a fast dry wheel, and once the temper is gone the tool will not hold an edge again until that section is ground away.

2,850 min⁻¹ on a 200 mm (7.87 in) wheel is a conventional speed for a general workshop grinder, and it is faster than a woodworker sharpening chisels and plane irons would choose. The practical answer is to grind the primary bevel only, in light passes, moving the tool across the wheel, keeping the wheel dressed, and to do the finishing on stones. The large 40 mm (1.57 in) fine wheel helps here: it lets the full width of a chisel sit on the stone at once.

What the wheel diameter changes

A 200 mm (7.87 in) wheel cuts a shallower hollow into the bevel than the 150 mm (5.91 in) wheels common at this price, which leaves more steel behind the edge and makes the subsequent honing quicker.

The prices, and a missing market

€175 in Germany, €177 in France, €195 in Italy. Neither the Spanish nor the American listing carried a price when we checked, and the product does not resolve on amazon.co.uk at all — which is worth remarking on, because Record Power is a British brand.

The good side, and the catch

Strengths

  • A 40 mm (1.57 in) fine wheel, which is wide enough to grind a chisel edge in one pass
  • Two grades supplied, coarse and fine, so reshaping and refining are both covered
  • 200 mm (7.87 in) wheels give a shallower hollow grind than the common 150 mm (5.91 in) ones

Compromises

  • 2,850 min⁻¹ is fast for sharpening edge tools, and heat is what ruins them
  • Not sold on amazon.co.uk, which is odd for a British brand
  • No price on the Spanish or American listings
  • Two motor ratings published without an explanation of either

What comes up most often

Is this a lathe?

No. The search asked for a Record Power lathe and the listing at this reference is the RSBG8 bench grinder, part number 71551, described as a grinding machine with two wheels for sharpening metal tools. Entirely different machine; we review the one that exists.

Will 2,850 rpm burn my chisels?

It can. Heat is what destroys the temper of a tool edge, the thin steel at the very tip heats first, and a fast dry wheel gets there quickly. The answer is technique rather than a different machine: light passes, constant movement across the wheel, a dressed wheel that is not glazed, and a pause to let the steel cool. Slow-speed grinders exist precisely because this is easier to get wrong than right.

Why two motor figures?

The listing gives 0.55 kW and 0.39 kW without saying which is which. Twin ratings on an induction motor usually distinguish intermittent from continuous duty, but the page does not say so, and we are not going to decide it for you. Ask the seller.
