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" (3.175 mm)
- 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
