Alpen | Drill Bit HSS Cobalt 3.3mm

Hss
Cobalt
Jobber Drill Bits
Size:
Ø 3.3 x 65/36mm
Range of application:
5% cobalt-alloyed jobber drills with high heat resistance for drilling steels with tensile strength over 800 N/mm², especially suitable for high alloyed steels, bearing steels, hot/cold-rolled steel. Ideal for stainless steel.
Strengths
Self-centering, due to a special point shape
Drilling even with the highest thermal stress up to 600°
Fast, due to special drill grinding fast drilling progress and up to 50% less feed pressure required
Tensile strength over 800 N/mm²
Especially suitable for high alloyed steels, bearing-steels, hot/cold-rolled steel.
Ideal for stainless steel
High heat-resistance
Highly accurate centering
