Makita Schleifböcke 250W 2850 U/min

Product Information

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. 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. 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.

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

You could set up a lamp in your work area of course. But having a light attached to your grinder means never having to reposition it when you need to move it out of the way or when you need better illumination.

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. On the more negative side, although most of the motor housing on the Clarke bench grinder is made of metal, the base of the machine is made out of plastic which, although tough, would have been better if it too was made out of metal so as to increase long-term robustness. One other point to note with the Clarke machine is that the bench grinder is only designed to continuously operate for five minutes at a time before needing to cool off for five minutes. This can sometimes make using the bench grinder inconvenient especially with prolonged grinding jobs.

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. Cheap and cheerful is the Silverline Silverstorm 263511 bench grinder. Don't expect too much from this machine for such a low price. This is a light grinder only as it only has a small 150W motor, ideally designed for sharpening knives, chisels, and the like. Build quality is on the low side, and you cannot apply too much pressure to the grinding wheel otherwise it slows down or even stops. This bench grinder can not be used as a polisher, so if you are thinking of attaching other wheels to it, like a wire wheel, then forget it, it will not do a very good job of polishing. 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.

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. Ceramic wheels are usually blue or pink, or a combination of these two colors. How to set up your bench grinder 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. Buffing wheels come in 6” and 8” diameters, so you should have no trouble finding a wheel that will fit your grinder. Remember if a bench grinder is a brush-type motor you could use a rheostat or a dimmer circuit to control the speed on a pro-brand tool. Should you get a 6 or 8-inch table 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. 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! You can generally avoid this by using a rough grit wheel and slow rotation speeds, although this isn’t always practical. But at that speed it can be a bit too fast for sharpening tools, ideally, a speed of about 1700 RPM is better. 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.

Most pros use 8” grinders. They are better suited for heavy-duty work and are more appropriate for use with a buffing wheel or a wire brush. You can use your bench grinder as an effective buffer or polisher simply by attaching a buffing wheel in place of the grinder. 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. Pressing too hard could remove too much material and increase the possibility of overheating. Single-speed bench grinder comparison 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.
