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. 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. The Best way to stand a bench grinder is to simply bolt it down to a steel workbench, this is preferable over a timber bench, although a timber bench will work.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. 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.

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.In general, you will want to apply light and even pressure when pressing your tool or workpiece against the grinding wheel. Although they have smaller wheels than their 8” counterparts, many grinders with 6” wheels are surprisingly heavy. The best bench grinder for the workshop or garage runs at a consistent operational speed and delivers with minimal vibration. One notably nice feature about the Makita bench grinder is that the housing over each wheel contains an integrated light that lights up the grinding area. However, it should be noted that these lights only come on when the machine is in operation whereas ideally we would have liked to see them have a separate control switch so that they could remain permanently on if desired. This slow-speed bench grinder spins at 2850 RMP and is the best pro-choice for sharpening chisels if you don’t want a DIY variable-speed bench grinder.

Know the maximum speed of the grinding wheel and the bench grinder - When purchasing new grinding wheels, make sure that the maximum speed of the wheel is not lower than the rotational speed of the bench grinder it is to run on otherwise spinning the wheel at too high a speed can cause it to disintegrate during use and presents a safety hazard. 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.Speed control or speed. Essential for reducing or increasing the speed of the wheel according to the requirements of the job. 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. Apart from the bench grinder itself, there are some other tools and accessories you will need to have to perform a variety of tasks.

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. You do have to choose the right wheels for this grinder, as it can wobble a bit with cheaper wheels. But get some good quality wheels on it, and the performance is stable and reliable. Pressing too hard could remove too much material and increase the possibility of overheating. Single-speed bench grinder comparison Apart from the magnifying lens in the guard, this is a great grinder. My personal feeling is the magnifier is not useful and is distracting so it will be replaced with a standard one. The grinder is very quiet and well balanced. The built in lights are a great feature, more so if you have a dark shed. 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?You can generally avoid this by using a rough grit wheel and slow rotation speeds, although this isn’t always practical. 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.
