Pencil grinders rotate carbide burs and mounted points to remove light material in grinding, sculpting, deburring, and polishing tasks. Their slim, compact design allows for control and access to tight spaces. Tungsten carbide allows pencil grinder bits to cut, engrave, shape, machine, chamfer, and drill steel effortlessly. They come in popular flute styles like spherical single-cut and ball-shaped double-cut for enlarging holes.
Speed
A high-powered pneumatic pencil grinder can help you finish your work quickly and easily. The faster the speed, the more power it has, and the more effective it will remove material from your workpiece. Also, a higher speed allows you to make more precise adjustments. When choosing a pneumatic pencil grinder, consider its motor power and whether it has a throttle mechanism to control the speed. Electric models are rated by amps (corded) and voltage, while air-powered models are rated by motor power at 90 psi. Choose a grinder with the proper collet size depending on the type of materials you need to grind. Most models accept a 1/8″ shank, but you can also find grinders that accept a larger or smaller diameter. Additionally, look for a model with an adjustable air intake valve to ensure you get the right amount of pressure for your project. You can use the tool for more projects without buying new collets.
Durability
A high-quality pencil grinder has a durable build and is made of sturdy materials. They have a few moving parts and are lightweight, ensuring you can use them without hurting your hands. Look for a model with a slide throttle that allows you to control the speed of your tool. This feature helps you avoid overheating, giving you more control over the tool. A good pencil grinder bit is made of tungsten carbide, which is quite complex and dense. This allows it to perform well on different types of materials. You can cut, grind, shape, mill, drill, chamfer, and engrave metals. It also works effectively on stones like soapstone, sandstone, and alabaster. Pencil grinder bits with long shanks can easily reach hard-to-reach areas. This feature is helpful for industries that need to prepare bones or tissues for refiling procedures. Dentists use some of them to cut, shape and grind bone and tissue for dental implants. They can also be used for making attractive shapes and designs in the bone.
Ease of Use
A high-quality pencil grinder has a pen-shaped design that makes it easy to hold and operate. It also comes with a set of bits, making it versatile and suitable for different tasks. The tool is also lightweight and slim so that it won’t interfere with your talent. It works well with standard power tools, especially die grinder machines. This type of grinder is typically used in industrial settings to process metals like aluminum, soft steel, and zinc. It can also be used on non-metal materials such as stone, book board, wood, and ceramic tiles. Its tungsten carbide material allows the bit to cut through ferrous and non-ferrous metals. It can also carve, shape, mill, drill, chamfer, and engrave. It is also ideal for steel, copper, bronze, and brass materials. It also has a smooth and consistent cutting action. The bits are available in two popular flute styles: aluminum single-cut and double-cut. The sphere single-cut is ideal for making indent drills, while the ball-shaped double-cut is ideal for enlarging holes.
Power
A high-quality pencil grinder is quite powerful. It also requires no lubrication, which saves you time and effort. It can be used for several tasks like resurfacing, deburring, shaping, chamfering, and weld seam removal. It works on ferrous and non-ferrous materials and can quickly adapt to any skill level. It comes in a wide range of shank sizes to suit different applications. Some models are designed with long shanks that allow them to reach areas that ordinary bits cannot. They are often used in preparing bone and tissue and other jobs requiring stability, precision, and accuracy.
Weight
If you use your grinder for long periods, it must be lightweight. A lighter tool will be easier to control and help prevent you from getting tired. An excellent pneumatic pencil grinder will weigh around a pound, making it very easy to handle and move from one task to another. It will also be compact, meaning it won’t take up too much space in your toolbox or workspace. This small and slim tool is perfect for reaching into tight or hard-to-reach spaces that would otherwise be difficult to access with a regular die grinder. It rotates at 56,000 rpm and has a twist throttle that allows you to control its speed. This model is also very quiet, so you won’t have to worry about disturbing any other workers in the area with its noise. It can be used for deburring, contouring, chamfering, fettling, and weld seam removal. Its collet accepts burs and mounted points with a 1/8-inch shank diameter.
