Description
- Polished flutes
- Used on thru holes for heat treated steels, hard cast irons and other hard materials
- Finishes are much better as spiral flutes tend to bridge interruptions such as keyways, slots, or intersecting holes
- Left spiral flutes should not be used on blind holes
- Carbide tips brazed to tough hardened alloy steel body, except expansion reamers which are not hardened
- Polished flutes for easy chip flow
- Precision ground cutting edges
Modifications
- Modified tool diameter - priced below
- Closer tool diameter tolerance
- Cutting diameter reduced for step or pilot
- End chamfer other than 45º
- End cutting or corner radius
- Increased / decreased circular margin
- Increased / decreased tool diameter back taper
- Shortened shank or reduced shank diameter
- Flat(s) or tang on shank
Coatings available:
- TITANIUM NITRIDE - TiN
- TITANIUM CARBONITRIDE - TiCN
- ZIRCONIUM NITRIDE - ZrN
- AL TITANIUM NITRIDE - AITiN
