- Item Features
- Standards
- Application
- Parabolic flute configuration with proprietary Convoflute flute design offers wider flute space, dispersing chips away from the cutting edges more rapidly and increasing coolant flow
- Engineered for deep hole drilling up to 8XD to 12XD, depending on drill diameter
- 135 deg K-notch split point is self-centering and uses reduced thrust for easier penetration
- Titanium nitride (TiN) coating adds lubricity and hardness, enhancing chip flow, finished hole quality and drill life
- -0.0007 in drill diameter tolerance
- +/-0.125 in overall length tolerance
- +/-0.125 in flute length tolerance
- +/-5 deg point angle tolerance
ASME/USCTI Standard
