Product Information

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. 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. 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. Dress the bench grinder periodically - Grindstone surfaces slowly wear down and often become clogged with metal filings during use. To rejuvenate the grinding surface, use a diamond-studded dressing tool to eliminate the metal filings and to expose fresh grit on the grindstone wheel surface. One way to be sure that you have dressed the wheel sufficiently is to draw a pencil line on the wheel and continue the dressing process until the pencil line disappears. Note, however, that the dust created from grindstone dressing is hazardous to your health so make sure to wear a dust mask! 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.

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

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. The Draper 29620 is a middle-of-the-range bench grinder with a 370W motor allowing it to handle some heavy duty grinding. In general, it is solidly built, the wheels are well-balanced, running smoothly with little vibration. The machine comes with 36 grit and 60 grit grinding wheels, which are a little too corase for delicate blades, but as with most other bench grinders the grinding wheels can be swapped out for other types of discs if need be. The unit weighs a hefty 12 kg so it is unlikely to move much but it can be bolted down to the workbench using only two holes in the base of the unit. Overall it is a good medium-level bench grinder, however, it is let down by the inclusion of less-than-adequate tool rests which can deform when grinding something substantial, and the fixings of the tool rests and various other components on the machine, are woefully below the standard of what is otherwise a good machine. In general, you will want to apply light and even pressure when pressing your tool or workpiece against the grinding wheel.

Bench Grinder

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. Fast speeds aren’t usually an issue for heavy-duty jobs for which you will probably want your grinder going at full bore the entire time. 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. 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.

Assuming the reception of a relatively flawless machine, the Titan TTB521GRB is, for the most part, a relatively smooth running bench grinder. However, a common issue with the Titan bench grinder is the often heavier than expected vibration as the wheels gain speed at start up. Fortunately, the vibration usually subsides when the machine reaches its normal running speed. To help with the vibration, the machine has been endowed with rubber feet as well as well-positioned screw holes in its base for securing it to the workbench. 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.

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.
