How Does Pencil Grinder Work?

If you have wondered how a pencil grinder works, you are not alone. There are a variety of models and features available on the market. These include the size, RPM, power, and protective goggles. Here are some of the things to consider when buying a grinder.

Pencil Grinder Work


A robust pencil grinder, like those sold at, is a multipurpose hand tool that can grind pencils, erasers, and other objects. A 4.2-amp motor drives the 25,000 rpm collet grinder with the DWE4887. You can adjust its speed of it thanks to its design. It can also handle accessories up to 1/4 inch in diameter. It weighs 3.65 pounds and has a 14-inch total length.

While air grinders are powerful, determining their power can be a challenge. Because the units are not usually rated by horsepower, it can be challenging to determine how much power they have. The best power indicator is often given in cubic feet per minute (CFM) or air consumption, ranging from 1.5 CFM for a pencil-grip precision air grinder to 6 CFM for a heavy-duty model. CFM and horsepower are different, so check the manual to ensure you’re purchasing the right one.


Size is an important consideration when choosing a pencil grinder. You need to choose a size that will accommodate the size of the point. The largest size comes with a 1/4″ collet, while a smaller size may be better for finer grinding applications. A 1/4″ shank is also more durable and can handle more pressure. Many of these tools also come with an adjustable roll throttle for varying speed settings.

A 1/8″ pencil die grinder from Astro is the perfect size for heavy-duty grinding applications. This machine is easy to handle at 5.2 x 14.5 x 19.7 inches and features a powerful motor that can grind dies, rotors, and brake pads. The grinder has a built-in air hose, brass coupler, two wrenches, and a custom carrying case.


Choosing a pencil grinder with an appropriate RPM depends on the task you intend to perform. A lower RPM is suitable for general grinding, deburring, and polishing work. The SLP-83150 is one option with a compact design and lower RPM. It is manufactured in the United States in Fenton, Missouri. As it is drop-shipped from the manufacturer, delivery time may be longer than usual. However, it is an excellent choice for small spaces and confined spaces.

Protective goggles

Protective goggles are an essential part of a safety equipment kit. They help keep you safe from a variety of hazards. Even simple actions like snipping a copper wire can cause small debris to fly into the air. Protective goggles are designed to keep your eyes protected at all times.


A high-performance pencil grinder should be powerful enough to grind large and small objects at high speed. Unlike manual grinders, pneumatic hand tools do not produce noise and are comfortable. They are ideal for deburring confined spaces, cleaning rough castings, and machined parts. They used a shanked carbide burr and mounted points.

Pencil grinders commonly have a collet that accepts burs with a 1/8″ shank diameter. Pencil grinders with this collet generally have a smaller shank but can accommodate various burs.
