Product Description

HSS Cobalt Jobber Drill Bit

Size: 11.5 x 142/94mm

Range of application

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