- Application
- Item Features
For drilling mounting holes for socket head cap screws
- Drills 45 deg chamfered holes to be tapped to produce approximate 70% thread
- The dual cutting diameters produce holes properly sized for each size screw
- The through hole style produces holes with a body diameter slightly larger than the major diameter of the screw
- The tapped hole type drills holes with the diameter needed for tapping the holes to approximately 70% thread
- Both types also produce a counterbored area correctly sized for the screw head
- Suitable for a range of ferrous and non-ferrous metals and alloys and non-metallic materials
- The cutting lengths are sufficient to permit repeated sharpenings
- Cuts both body and counterbore diameters in a single pass
- Straight shanks that corresponds to the drill diameter
- Ground from the solid
- Cylindrically ground
- Permits repeated sharpenings
