Rocky Mountain Twist Cobalt Jobber Drill

Rocky Mountain Twist jobber drills are industrial-grade bits engineered for high-performance drilling in the toughest materials.  Manufactured in the USA from M42 Cobalt High-Speed Steel (HSCO).

Key Features

  • Premium Cobalt Substrate:  Manufactured from M42 HSS-Co8%, which offers excellent red-hardness for drilling into alloyed steels, stainless steels, and cast iron.
  •  135° Split Point:  Self-centering prevents "walking" at entry and reduces required thrust, making it ideal for both automated CNC and manual drilling.
  • Features a heavy web design for increased durability and reduced drill breakage under load - ideal for deep hole drilling
  • Made in the USA to exacting NAS (National Aerospace Standard) specs for industrial reliability

Applications

  • Steel
  • Stainless Steel
  • Hardened Steel
  • Titanium
  • High Strength Alloys
