Description
- Die drill - negative angle cutting edge
- Drill body diameter smaller than tool diameter to prevent gauling
- Carbide tip high temperature brazed to hardened tool steel body
- Smooth flutes for effective chip flow
- Precision ground to insure concentricity of tip & body
- All dimensional & element tolerances conform to one of:
ASME/ANSI B94.11M
ISO - International Organization for Standardization
NAS 907 - National Aerospace Standards
USCTI - United States Cutting Tool Institute (formerly MCTI)
Modifications
- Modified tool diameter
- Modified metric tool diameter
- Modified point and / or angle
- Shortened shank or reduced shank diameter
- Reduced shank diameter
- Flat(s) on shank
Coatings available:
- TITANIUM NITRIDE - TiN
- TITANIUM CARBONITRIDE - TiCN
- ZIRCONIUM NITRIDE - ZrN
- AL TITANIUM NITRIDE - AITiN
Use
- For drilling hardened steel in the range of 35 to 65 Rockwell C
- Will cut without annealing the workpiece
- Light feed with steady pressure - clear chips frequently
- Flood the cutting point with coolant
