Product Information

As for other types of activities that can be undertaken on the bench grinder, the Clarke CBG6RP machine is not powerful enough for regular polishing work but, at a stretch and if not too much pressure is applied on the wheel, can be used for some very light buffing when used with an appropriate polishing wheel. The Clarke CBG6RP 6-inch bench grinder is relatively heavy considering its motor size coming in at around 8kg which bodes well for greater stability on the bench top, but not so for moving it around a lot. In fact as with most bench grinders, the Clarke machine should be bolted down to the bench top for maximum safety and in this regard there are four screw holes moulded into the base of the machine designed to permanently fix it into place.

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.

Larger bench grinders are useful for basic sharpening of chisel blades and the like and metal-polishing tasks, and you will save money in the long run because you won’t have to keep changing the wheels. As with most other consumer bench grinders, the Titan comes with coarse and fine grinding discs, namely 30-grit and 60-grit wheels, but as an added bonus, a useful brush wheel is also included in the box. Unfortunately, however, not a lot of thought has gone into the use of wire wheels on the Titan grinder as the included one can sometimes partially brush against the wheel guard securing bolts which protrude a fair amount. Continuous striking of these bolts with the wire wheel will eventually damage them making removal of the wheel guard more problematic. One option is not to use the wheel guard at all when using a wire wheel but this poses an increased safety risk to the operator and is not recommended. 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! 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.

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.

Bench Grinder

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. 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. 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. You will definitely get more use out of an 8” grinder and a variety of wheels than you would with a 6” grinder and the same set of wheels. Choosing the best bench grinders
