Description
- Special plus .0000", minus .0002" tool diameter tolerance
- Polished straight flutes with steel cutting grade flute long carbide
- Special steel cutting tool geometry:
Positive radial rake (behind center)
Narrow circular lands
Minimum back taper - Longer flutes than Type 450 on .5971" tool diameter and larger for straight deep holes
- 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
- Material specific reamer shanks are ground to next smallest shank diameter listed in NAS 897 if tool diameter is within .005" of shank diameter
Options

- 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
- 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
- These precision ground reamers should be used in pairs, .0005" and .0020" under the dowel pin diameter. The .0020" smaller holes assure a tighter dowel pin fit, so all the pins will remain on the same side upon disassembly. Especially useful in plastic or die cast molds and machines when assembled sections are subject to shearing stress, yet require occasional disassembly.
