5% cobalt-alloyed jobber drills with high heat resistance for drilling steels with tensile strength over 800N/mm, especially suitable for high alloyed steels, bearing-steels, and 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 800N/mm
Especially suitable for high alloyed steels, bearing-steels, hot/cold-rolled steel
