Makita Schleifböcke 250W 2850 U/min

Product Information

For most other applications, however, you will likely need to adjust the speed depending on the material you are grinding. In particular, you will want to set your grinder to slower speeds when sharpening chisels, to avoid overheating the metal. The BG150CX bench grinder from Sealey is the first member of a range of bench grinders from the company. The BG150CX represents their most basic model, which means it has the minimum of features but also the lowest of prices. Like many other budget machines, it belongs to a family of ‘generic’ machines that are often sourced from the same manufacturer, coloured and then badged with the insignia of the retail distributor, in this case, Sealey. 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. 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.

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

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.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. As for build quality on the Titan machine, this can be variable from component to component. For example, the tool-rests on the Titan bench grinder are not of the best quality and can be deformed if enough pressure is applied. In addition, although they are adjustable in the horizontal ‘closer / further away’ dimension, they cannot be angled upwards making the consistent sharpening of tools, such as chisels and plane irons, more challenging. In other places, the build quality appears better, for example, when switching off the machine, the wheels take quite some time to come to a rest suggesting the use of decent spindle bearings.

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. Do not use a bench grinder to grind aluminium - Bench grinders are designed for grinding down steel and similar metals. However, never use a bench grinder to grind down aluminium as the filings generated from this metal can accumulate in the wheel, which then can ignite when the wheel becomes hot during a later grinding session. This can cause the wheel to disintegrate as it is being used, with the resulting danger to the user. Lower bench grinding speeds help keep heat build-up under control - If available, use a lower bench grinding speed to keep the heat build-up, on both the object being ground and the grinding wheel itself, under better control. Like most other bench grinders, other types of discs, such as wire wheels and polishing mops, can be swapped into the place of the bog-standard grinding stones. However, similar to other low-powered machines, this is not recommended as the limited torque means that the machine easily grinds to a halt if too much pressure is applied. 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.

If you do need the more acute curvature provided by a smaller wheel, you can simply swap out the standard 8” wheel for others that are better suited for the job you need to do.
