Rank #6 in Best Bench Grinder 2026: 10 Ranked, Specs That Contradict Themselves
Sealey BG150CX 150 mm Bench Grinder, 150W
Price and rating as shown on Amazon when we collected them. Both change.
The Sealey BG150CX is a 150 mm bench grinder with a 150 W induction motor, priced at £49.93 and placed sixth in this guide. The listing carries 4.5 stars from 141 ratings, and the best sellers rank printed in its own specification block reads 2 in Bench Grinders. It is supplied with coarse and fine aluminous oxide stones, eye shields, spark arrestors and tool rests.
Its specification sheet is where the product gets interesting. The Item Weight field says 5.32 kg, while the specification table printed inside the bullet above it says 6 kg. The dimensions field gives 10L x 10W x 10H millimetres, while that same bullet table lists 205 mm length, 303 mm width and 211 mm height. And the field labelled "Horsepower" reads "150 Watts" — the identical figure shown in the Wattage field, so the horsepower column is not giving you horsepower at all. Every number on this page comes from the Amazon listing, not from testing we carried out ourselves.
How those 141 ratings break down
An average hides its own shape. This is the spread behind the 4.5 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“At the price point, I absolutely cannot fault it. I've had lots of use out of it over the past couple of months. I use it mostly for automotive hobby work with a wire wheel attachment for rust removal. It's not massively powerful, if you really lean into it, it will slow the motors, but that's to be expected. Once you get the hang of how to work with it and not against it, it's brilliant. A great edition to the shed!”
Verified purchase“Quality could be better but value for what it isNot high speed but power ful enough for small thingsNeeds a stronger engine as any pressure slows it up”

Questions people ask
How powerful is the Sealey BG150CX?
The listing gives it a 150 W motor on a 230 V supply with a no load speed of 2950 rpm. Two Amazon reviewers say it slows down when they press hard into the work.
What size wheels does it take?
150 mm. The Sealey listing says it is supplied with coarse and fine aluminous oxide grinding stones for general workshop grinding and sharpening.
How heavy is the Sealey BG150CX?
The listing contradicts itself. The specification table quoted in the bullet says 6 kg, while the Item Weight field says 5.32 kg.
Is the 150 figure the motor or the wheel?
Both are 150, and they mean different things. The motor is 150 W and the wheel diameter is 150 mm, which is why the two numbers are easy to confuse in this listing.
What is included with the grinder?
The listing states eye shields, spark arrestors, tool rests and two grinding stones, one coarse and one fine, plus a specified axle diameter of 13 mm.
What does the Horsepower field say?
It says "150 Watts", the same figure as the Wattage field. The field labelled Horsepower is therefore repeating a wattage number rather than giving a horsepower rating.
