Drill bit sharpening angles

Drill sharpening angles refer to the angles formed between the cutting edges of a drill bit and the axis of the drill bit. The angles vary depending on the type of material being drilled and the specific purpose of the drill bit. Here are some of the most common drill sharpening angles and the materials they are used for:

  1. 118-degree angle: This is the most common angle for general purpose drilling in materials such as wood, plastic, and soft metals.

  2. 135-degree angle: This angle is used for harder materials such as stainless steel, cast iron, and other metals.

  3. 90-degree angle: This angle is used for drilling in soft materials such as leather and rubber.

  4. 150-degree angle: This angle is used for drilling in plastics and other similar materials that are prone to melting.

  5. 60-degree angle: This angle is used for drilling in harder materials such as hardened steel and other high-strength alloys.

  6. 90/60-degree angle: This is a combination of the 90-degree and 60-degree angles, and is used for drilling in materials such as copper and brass.

It is important to choose the correct sharpening angle based on the material you are drilling to ensure that you achieve the desired results and prolong the life of your drill bit.
