HSS Center Drill
There are two types of center drills:
Type A: Center drill without cone guard
Type B: Center drill with tapered shroud
When machining a center hole with a diameter of d=1~10mm, the center drill does not have a cone shield (type A); for longer workpieces
Process and higher precision requirements, in order to avoid damage to the 60 degree centering cone, center drill with guard
Cone (Type B) for general use

Instructions for use of the center drill:
1. The user must reasonably select the center drill model according to the hole type and straight hole size of the machined parts.
2. The hardness of the workpiece to be processed is between 170-200HB. 3. Before using the tool, it must be coated with anti-rust grease
Clean up to prevent chips from sticking to the cutting edge and affecting cutting performance. 4. Surface
The workpiece to be processed should be straight, without air bubbles or hard spots, so as not to damage the tool.
