Tiangong spiral high speed steel center drill

1. Material:

Using high-quality high-speed steel, some high-end models use cobalt alloy, etc., with a hardness of up to HRC63-67, strong wear resistance, and more durable than ordinary drill bits.

Some products are treated with coatings such as titanium nitride (TiN) to reduce the friction coefficient and further improve wear resistance and service life.

2. Precision manufacturing:

The drill tip is reasonably designed, such as the use of a 135° standard blade angle, and some models are optimized to a self-centering design, which can reduce drilling deviation, improve positioning accuracy, and make drilling more accurate.

The spiral groove is scientifically designed and the chip removal is smooth, which can effectively reduce cutting heat, avoid the drill bit from getting stuck or broken due to poor chip removal, and ensure smooth processing.

3. Superior performance:

The blade is sharp and the drilling speed is fast, which can improve processing efficiency.

High precision, small drilling deviation, small hole expansion, few burrs at the hole exit, and good processing quality.
