ALPEN 1,7mm COBALT DIN 338 Drill Bit

Description

Range of application:

5% cobalt-alloyed jobber drills with high heat-resistance for drilling steels with tensile strength over 800 N/mm², specially 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
• Specially suitable for high alloyed steels, bearing-steels, hot/cold-rolled steel.
• Ideal for stainless steel
• High heat-resistance
• Highly accurate centering
