Description
- Cam relieved 120º point
- Carbide tip brazed to tool steel body
- Precision ground to insure concentricity of tip and shank body
- 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
- Metric tool diameter
- Modified point and / or angle
- Shortened shank or reduced shank diameter
- Flat(s) on shank
Coatings available:
- TITANIUM NITRIDE - TiN
- TITANIUM CARBONITRIDE - TiCN
- ZIRCONIUM NITRIDE - ZrN
- AL TITANIUM NITRIDE - AITiN
Use
- For shallow holes, approximately 2 tool diameters deep
- Short heavy construction allows more rigidity for tough applications where longer length drills are not needed
