EXTOL INDUSTRIAL Step drill bit with chip breaker, 4-32mm/by 2mm, HSS-Co 8701194
EXTOL INDUSTRIAL Step drill bit with chip breaker, 4-32mm/by 2mm, HSS-Co 8701194
The EXTOL INDUSTRIAL step drill bit is designed for drilling holes with a continuously increasing diameter from 4mm to 32mm. It is suitable for working with metals, plastics, and steel sheets up to 4mm thick. The drill bit is made from HSS-Co high-speed steel with 5% cobalt, which gives it high hardness and wear resistance. The TiAlN surface coating increases its thermal resistance and service life, even during demanding use.

Durable design for smooth drilling
The drill bit is based on high-speed steel (HSS) with a 5% cobalt alloy, which ensures high hardness and wear resistance. In addition, the surface features a TiAlN coating that increases thermal resistance and enables drilling at higher speeds. The design with a chip breaker helps to ensure smooth drilling without deforming thin materials such as sheet metal. The three-sided shank prevents the drill bit from slipping in the chuck and contributes to precise power transfer.
