Makita Schleifböcke 250W 2850 U/min

Product Information

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.

As with all power tools, getting the most out of your bench grinder involves knowing what you will use it for and what the best features and accessories are for the job. I have found the Makita bench grinder both easy to use and attain a good quality hollow grind finish on chisels and wood plane irons. 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. Buffing is pretty easy once you know how, although you will first have to become familiar with how different surfaces react to the buffing wheel.You can then securely bolt down the grinder to hold it firm in operation. You can also bolt down replaceable bits of plywood onto a steel workbench to have a soft working area. It’s a good idea to also bolt down a good bench vise. But at that speed it can be a bit too fast for sharpening tools, ideally, a speed of about 1700 RPM is better. 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.

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.
