Left Hand Carbide Tool Bit

Carbide tools have a small piece of tough carbide brazed to the tip of a softer steel shank. These tools are recommended for cutting hard or abrasive materials. Carbide tools can retain their hardness at temperatures up to approximately 1700°. This permits a higher cutting speed and faster feed rates.

They are typically harder to sharpen than their HSS counterparts. A silicon carbide or diamond grinding wheel must be used. The shape of carbide tools is also more critical than the shape of high-speed steel cutters, but their cutting ability on tough or abrasive materials makes them very popular. If you are cutting a material that quickly dulls your HSS cutters, you will find carbide tools might be just what you need.

NOTE: A tool is named by the direction from which the chip leaves the tool; so a left-hand tool has its cutting edge on the right and the chip peels off to the left.

About Grinding Your Own Tools

As with any machining operation, grinding requires the utmost attention to “Eye Protection.” Be sure to use it when attempting the following instructions. When working around grinders it is an absolute necessity to wear EYE PROTECTION. Grinding debris is thrown out at high velocities and can damage not only eyes, but also expensive glasses. Wear safety glasses or a full face shield.

For safety, a bench grinder should be mounted to something heavy enough so it will not move while being used. The tool support must be used and should be set at approximately 7°. Few people have the skill to make tools without a tool support and in essence it’s wasted effort. Tool supports are usually made up of two pieces that allow you to set your tool rest above or below center.
