What is a Bench Grinder Wheel?

Bench Grinder lies in the classification of benchtop grinding devices which are used for driving abrasive wheels. Bench Grinder consists of bed fitted to hold the work piece and is used for hand grinding of cutting tools as well as rough grinding. It depends on the grade and bond of grinding wheel.

How Does a Bench Grinder Wheel Work?

The grinder works by removing material through abrasion from work piece in progress of cutting which may generate a lot of heat. A coolant is incorporated for cooling the work piece when temperatures go higher.

Work Piece Material

Most of the bench grinders’ wheels are the vitreous-bond type of wheels. These wheels work best achieving the task they are intended for although they still inhibit cracking risk. Softer grinding metals such as aluminum are not grinded using wheels which are designed for hard metals such as steel. These soft metals are lodged in wheel’s pores which later on expand due to the grinding heat produced. Such an occurrence may dislodge grinding wheel pieces leading to an injury.

Wheel Speed

The paper blotter of the wheels come printed with the maximum ratings of RPM. Then the RPM of the grinder should either be lower or equal to the maximum speed of operation which is indicated as maximum on the tag on the grinder’s wheel as not to be exceeded. If the grinder wheel is over sped, it may explode which is dangerous as it can either kill or injure the operator similarly to a gunshot.

Spark Arrestor Replacement and Tool Rest

Tool rest should be very tight and also fitted within 3 to 2 millimeters of the grinder wheel. The reason behind this is to prevent any slipping of work piece down between tool rest and wheel. Spark arrestors are used for catching stray sparks.

Grinding occurs as work piece is on tool rest for prevention of sudden slips whereby the wheel momentarily grabs work then yanks the wheels out of the hand of the operator or else pull to the wheel side the hand.

Wheel Sides and Periphery

Bench grinder whose wheels are designed for periphery grinding are highly prohibited to be used on a bench grinder for side grinding. The biggest threat with using the peripheral for side is a wheel explosion. Some cutter and tool grinders have wheels which are cup-shaped which can do side grinding.


When you are grinding metal on grinding wheel which is driven by power the work piece is heat up quickly. Many bench grinders have no coolant as they are the dry kind but then it requires often dipping of the work piece in pan of water so that it cools in order for it to maintain its temper or burn the hand of the operator. The pans of water for easy reach and safety are mounted under the grinder. Frequent dipping in water is needed for high or medium carbon work pieces as they are already tempered and hardened to avoid high heating which is followed by quenching substantially hence destruction of heat treatment already in existence.

Grinders used for sharpening knives are the wet kind whereby its wheel bottom has a coolant. You can also incorporate a tube on the wheel’s top for delivering the coolant in a stream. Such grinders are classified in benchtop grinders’ class.

Wheel Guards

Wheel guards are used for intercepting fragments of a wheel which has exploded for them not to damage the surroundings or kill people. This explains why grinders with no guards are not allowed.

Why Should You Choose Your Bench Grinder Wheels Carefully

Bench Grinder Wheels Types:

Straight wheel

These are the most common wheel style. This style is only used for periphery and hence produce a surface which is slightly concave. Straight wheels generally are used on centerless, surface and cylindrical operations. These type of wheels are varied in terms of width, diameter and size of face depending on work class it is used on and the machine’s power.

Diamond wheel

These are the grinding wheels fitted with industrial diamonds which are bonded on the periphery. Used to grind very hard materials like concrete, gemstones or carbide tips.

Saucer wheel

Used for grind twist drills and milling cutters. Common in areas with no machines as such areas make use of saucer wheels to maintain blades of the saws.

Tapered wheel

This is the straight wheel which tapers the outward directing it to the wheel’s center. Unlike straight wheels, there arrangement is stronger to accept loads which are highly lateral. Used for primarily grinding gear teeth, thread.

Dish cup wheel

This are the most shallow cup designed grinding wheels. The wheel’s thinness allows crevices and slots grinding. Used for jig and cutter grinding.

Cut off wheels

Also called parting wheels. These are wheels which are self-sharpening, with thin width and fitted with radial fibers for reinforcement. Used often in construction industry to cut reinforcement bars.

On What to Pay Attention When Choosing Wheels


The wheels are usually 5 inches by 18 inches.


Grit form part of abrasives on grinding wheels which ae grains and grits. Grains are the ones which cut the metal while the grits are responsible for holding together the grains as they are cut. Wheels structure is determined by the spacing of grit and grain. The choice of a wheel is dependent on the way in which the wheel will interact with work piece. Ideal choices should be able to remain sharp with less dulling as it creates other cutting points when it becomes dull.

TIP: Easy Grinding Wheel Dressing Tool

Material of the wheel bonds which includes;

Vitrified bonds

The vitrified bond of the wheel is based on glass and it’s made through feldspars and clays vitrification.


Bench Grinder rubber wheel bond is made from Synthetic rubber or natural rubber.


The grinding wheels resinoid bonds are based on resin. The resin is made from distillates of petroleum or plants.
