Without a variable speed control, you will have to constantly turn the motor on and off to slow the wheel down. In addition to placing undue stress on the starter mechanism, this can get very annoying after a while. The covers features built-in task lights for precise work, while the motor is a split capacitor type for higher efficiency with reduced noise and vibration. 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. 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! 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.

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. 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.Whether you go for a pro or DIY model though, one thing that’s good about DIY brands is the variable speed setting. 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. 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. Although they have smaller wheels than their 8” counterparts, many grinders with 6” wheels are surprisingly heavy.

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. 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 An integrated light isn’t essential, but it does come in handy for working in low-light conditions. Even if your workshop is brightly lit, having a light on your bench grinder will let you see the workpiece more easily.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. Some people control the speed of their single-speed grinders with a rheostat or a dimmer circuit [ 1]. Although this will work with grinders that have brush-type motors, a grinder with an induction motor will burn up when operated in this manner. Work light. An onboard light will help you see what you are doing and spare you the hassle of setting up a lamp near your work area. 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. Bench grinders are power tools equipped with abrasive grinding wheels. Their primary function is to grind down various types of materials, typically wood or metal.

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. 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.Ceramic wheels are usually blue or pink, or a combination of these two colors. How to set up your bench grinder My name is Aaron, and thank you for reading my article. As a qualified carpenter, I share some tips here at Bangingtoolbox to help provide better DIY information on the internet. 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. You can use your bench grinder as an effective buffer or polisher simply by attaching a buffing wheel in place of the grinder.
