M42 Co8 Cobalt Drill Bit – Individual Sizes
Need to replace one drill bit or need an uncommon metric diameter?
ABRASIVESTOCKS M42 Co8 cobalt drill bits are available individually in 91 different sizes from 1.0mm to 10.0mm, increasing in precise 0.1mm increments.
This makes it easy to select the exact drill diameter required for precision metalworking, fabrication, engineering, maintenance and workshop applications.
M42 HSS with 8% Cobalt
Manufactured from M42 high-speed steel containing approximately 8% cobalt, these drill bits are designed for applications requiring good heat resistance, hardness and wear resistance.
They are particularly suitable for drilling tougher materials where standard general-purpose HSS drill bits may wear quickly.
