Description
- Coolant outlets in each flute
- Polished flutes; flute long carbide on .2841" tool diameter and larger
- Tool geometry and carbide grade appropriate for material being machined
- 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
- 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
- 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
Use
- Flute coolant outlets for reaming thru holes as chips are flushed forward through the hole being reamed
- Improves hole finish and permits higher feeds & speeds with longer tool life
