Description
- Type "C" with short carbide tip
- Straight polished flutes and taper shank
- Tool geometry and carbide grade appropriate for material being machined
- Carbide tips brazed to tough hardened alloy steel body
- Polished flutes for easy chip flow
- Precision ground cutting edges
- “Taper Shank No.” refers to American Standard taper series (formerly Morse taper series) per ASME/ANSI B5.10
- Material specific reamer shanks are ground to next smallest shank diameter listed in NAS 897 if tool diameter is within .005" of shank diameter
Modifications
- Modified tool diameter - priced below
- Metric tool diameter
- 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
- Shank whistle notch for set screw
- Smaller taper shank
Coatings available:
- TITANIUM NITRIDE - TiN
- TITANIUM CARBONITRIDE - TiCN
- ZIRCONIUM NITRIDE - ZrN
- AL TITANIUM NITRIDE - AITiN
