Size: 4.0 x 75/43 mm

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, 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 800 N/mm²
