There are countless uses for bench grinders. Often used for sharpening tools like blades and drill bits, when a dedicated sharpener is not around , they are also effective for cleaning, buffing, or polishing surfaces. One notably nice feature about the Makita bench grinder is that the housing over each wheel contains an integrated light that lights up the grinding area. However, it should be noted that these lights only come on when the machine is in operation whereas ideally we would have liked to see them have a separate control switch so that they could remain permanently on if desired. Independently adjustable tool rests. compensate for worn wheels and allows for different grinding angles.

With a single-speed high RPM bench grinder, there is more risk of overheating when sharpening tools, and you could ruin a perfectly good edge. The Makita GB602 bench grinder is the Makita Corporation’s contribution to the 6-inch bench grinder tool category and as expected from the Japanese company, the GB602 is a precision tool with grinding wheels that show little vibration and a motor that makes relatively little noise. The motor power in the Makita bench grinder is 250W, powering the grinding wheels to 2850 rpm, and making the GB602 effective at medium level grinding of larger tool blades and power tool bits. It is, however, not the most powerful 6-inch bench grinder on the market, and unsurprisingly, pressing too hard on the grinding wheels can slow or even stop their rotation. Fortunately, the slowing or stopping of the wheel rotation only occurs when excessive pressure is applied and is not really relevant to normal grinding practice. Other than that, for commercial and industrial use, you will get a much better life span with a pro brand under daily use. And therefore you should consider if you want a slow or fast speed bench grinder.So what size to get? After deciding on whether the bench grinder size will fit in the workshop space allocated for it, choosing which size is best is to some extent a matter of personal preference. The size of the wheel does affect some characteristics of the bench grinder, like a larger wheel has a faster angular velocity at the grinding edge affecting the rate of frictional heating, or smaller wheels are more curved at the grinding point which can cause slight differences in bevel formation, however, for the most part, the effect on actual function is minor. Power The Dewalt or a Jet bench grinder are popular choices, depending on if you want the best or the best value. Some people control the speed of their single-speed grinders with a rheostat or a dimmer circuit [ 1]. Although this will work with grinders that have brush-type motors, a grinder with an induction motor will burn up when operated in this manner. Pressing too hard could remove too much material and increase the possibility of overheating. Single-speed bench grinder comparison

Essentially, once you have decided on the grinding wheel diameter to go for, usually either 6" (150mm) or 8" (200mm), it simply then becomes a matter of buying the highest-powered machine that you can afford, while keeping an eye out for the features that each offers. Those features include the ability to change out the wheels for different types of grinding wheels, wire wheels, or polishing mops, endowing the humble bench grinder with a whole range of capabilities.

Like most heavy-duty grinders, the Dewalt DW758 8” only runs at a single speed. Even so, it does a great job of shaping tools, deburring, and removing rust spots. But at that speed it can be a bit too fast for sharpening tools, ideally, a speed of about 1700 RPM is better.

Bench Grinder Reviews in the UK: Which is the Best Bench

An integrated light isn’t essential, but it does come in handy for working in low-light conditions. Even if your workshop is brightly lit, having a light on your bench grinder will let you see the workpiece more easily. Make sure that the wheel has access to a reasonably wide area of your workpiece. You may have to remove the guard that normally provides protection when grinding, but be aware that the guards on some models are part of the main casing and are usually unremovable. Know the maximum speed of the grinding wheel and the bench grinder - When purchasing new grinding wheels, make sure that the maximum speed of the wheel is not lower than the rotational speed of the bench grinder it is to run on otherwise spinning the wheel at too high a speed can cause it to disintegrate during use and presents a safety hazard. White wheels are better for DIYers - White-coloured wheel s (as opposed to grey or light blue ones) are gentler grinding wheels that make it easier to achieve a sharp edge on a tool, however, they tend to wear down faster than their darker brethren. For DIYers who tend to use bench grinders on more of an occasional basis, these types of wheels are therefore usually more appropriate.

Apart from the magnifying lens in the guard, this is a great grinder. My personal feeling is the magnifier is not useful and is distracting so it will be replaced with a standard one. The grinder is very quiet and well balanced. The built in lights are a great feature, more so if you have a dark shed. Finally, one feature on the Titan that we don’t particularly like is the use of a 16 mm spindle bore. Most consumer bench grinders come with a 12.7 mm spindle and the majority of grinding wheels on sale to the consumer tend to cater to this smaller spindle, either by having 12.7mm bore holes or by coming which bushes that adapt them to this smaller shaft size. This makes finding replacement grinding discs and other wheel types for the Titan bench grinder slightly more difficult and seems like an unnecessary complication. On the other hand, all-pro made bench grinders like Dewalt, Makita, and Jet only come as a single-speed unit. Whether you go for a pro or DIY model though, one thing that’s good about DIY brands is the variable speed setting.

The Clarke CBG6RP 6-inch bench grinder is another member of the budget category of bench grinders designed for the at-home DIYer. It is a generic type of machine that has been manufactured in the Far East and then badged with the Clarke logo and branding. It has a 150W motor which is one of the less powerful motors that one gets in the 6-inch bench grinder lineup and as such, like the other 150W bench grinders on the UK market, the Clarke machine is really only designed for light metal grinding of small hand tools such as chisels and the like. Grinding on the Clarke machine is carried out using the 20mm-width coarse and fine grinding wheels that come with it. However, for full sharpening of tools as well as blades, a yet finer grit wheel is recommended or a manual whetstone should be used after the initial dressing on the default Clarke grinding wheels. The Clarke bench grinder uses a standard 12.7mm bore size so replacement wheels should be easy to come by. Grinders intended for DIY home use usually have 6” disks. They typically run at speeds of 3400 to 3600 RPM and are suitable for most basic home improvement jobs.The Sealey BG150XLW/98 is a powerful bench grinder that comes with a grinding wheel and one wire wheel. It has a 370W motor that is strong enough to grind some of the harder metals, and it can be used for longer than budget models before it needs to be given a rest to cool down. The wire wheel is useful for removing old coatings on metal objects such as paint or rust and of course other wheels can be swapped into place of the grinding wheel or the wire wheel as needed. The unit runs smoothly, with little vibration, but it still needs to be bolted down to the workbench to ensure it does not move at all. Niggles with the Sealey bench grinder are common to most bench grinders in this price range, for instance, care still needs to be taken not to put too much pressure on the spinning wheels as this will cause them to slow down, reducing its ability to effectively grind or polish.
