Centre drills
60° Angle with chamfer
form B
HSS + TiN = hardness 63 HRC, to machine steels up to 800 N/mm², copper, brass, bronze, aluminium up to 6% Si. The TiN coating  hardness 2300 HV increases the tool life by increasing wear resistance.

Centre drills with protective chamfer quarantee the centre obtained from any risk of blows and deformation.
The play resulting from the protective chamfer makes it easier to load parts between points on machine with automatic feed.
