PCD 45 Degree Angle Chamfer Drill Bit

A popular method for removing sharp corners to achieve a professional finish. Diamond tip, two grooves with ball bearing guides.

The specific process characteristics are as follows:

1. The knife body is made of stable SAE4140 steel rods processed by CNC. It is stronger than other straight knife bodies without losing flexibility. It is heat treated to a Rockwell hardness of 45RC; the grinding adopts "centerless grinding" processing and balance. Check that the true roundness makes the tool holder balanced when running at high speed.

2. Ultra-fine-grain carbide blades ensure a long service life.

3. High-frequency welding is used to ensure that the blade does not break, has no internal damage, is not easy to chip, and has excellent safety.

4. Teflon coating enhances surface wear resistance and high temperature resistance, reduces friction and facilitates chip removal.

Cutting depth: 18MM (other sizes can be customized)

Tool diameter: 48.9MM (other sizes can be customized)

Shank diameter: 12.7mm (other sizes can be customized)

Number of blades: 2 blades

NOTE: These miniature bearings have a limited service life and require periodic replacement.
