The Ultimate Guide to Drawbores: Types, Uses, and Benefits

Drawbores are a type of drill bit that is specifically designed for drilling holes in metal. They are typically made of high-speed steel (HSS) or tungsten carbide (TC), and are available in a range of sizes and shapes to suit different applications.

Drawbores are characterized by their ability to maintain a consistent cutting edge during the drilling process, which helps to ensure accurate and precise hole cutting. They also have a high level of durability and can withstand the high temperatures generated during drilling operations.

Some common types of drawbores include:

* Straight shank drawbores: These are the most common type of drawbore and have a straight shank that is inserted directly into the drill press or other drilling machine.
* Tapered drawbores: These have a tapered shank that is designed to be used in drill presses with a tapered spindle.
* Cobalt drawbores: These are made of cobalt, a hard and wear-resistant material that is well-suited for drilling very hard materials such as stainless steel and other high-strength alloys.
* Carbide-tipped drawbores: These have a tungsten carbide tip that is brazed onto a steel shank, providing a combination of strength and durability.

Overall, drawbores are an essential tool for anyone who works with metal, and can be used in a wide range of applications from machining to fabrication.
