5.5mm M35 HSS Cobalt High Speed Drill Bit - M35HSS055

5.5mm M35 HSS Cobalt High Speed Drill Bit - M35HSS055

Cobalt increases the strength of the steel and makes it more heat-resistant; this is an important factor in drilling hard materials because the friction of metal against metal can produce high temperatures that damage the material or the drill bit.

- Will perform and outlast normal HSS bits particularly if drilling tough metals
- Fully ground M35 HSS material increases drill life
- 135° Split point cuts faster and reduces wandering
- Precision engineered shank for accurate hole size
- Quick and efficient swarf clearance allows clog-free precision drilling
