Opening Drill®   
The Opening Drill® is an extremely effective tool designed to enlarge existing holes, eliminating the need for multiple boring passes. Adjustable cartridges cover a wide range of diameters reducing inventory cost.
Advantages
  • Opens an existing hole in a single operation allowing for large amounts of material removal while ignoring core shifts up to 1/8" (3.175mm)
  • Ideal on low horsepower machines while maintaining high penetration rates
  • Multi-insert design reduces chip size for easy chip evacuation
  • Can be used in rough boring operations
  • Suitable for use in lathes and mills
  • Diameter adjustment reduces inventory and cost
Features
  • Replaceable and adjustable cartridges
  • Indexable inserts available in AM300® and AM200® coatings as well as high rake and general purpose geometries
  • Coolant through
  • Integral shanks available for increased rigidity
