CHUCKING REAMERS — CARBIDE TIPPED

FOR REAMING STEELS, TOUGH STEEL ALLOYS & CAST IRON

TYPE 2480 — STEEL CUTTING — STRAIGHT FLUTES & STRAIGHT SHANK — FRACTIONAL SIZES

Steel cutting grade flute long carbide brazed to hardened tool steel bodies.
Special steel cutting tool geometry:
Positive radial rake (behind center).
Narrow circular lands.
Minimum back taper.
Longer flutes for straighter holes.
Straight shanks to ANSI specifications.

USE:

This carbide tipped reamer's design is based on our extensive development and design experience in manufacturing special reamers for reaming steel in the automotive industry. This design is proven in an industry where performance is carefully evaluated.
Traditional steel reaming problems have been reduced by the following:

1. Holds size longer because steel cutting grade carbide is utilized — but not just any steel cutting grade carbide as we discovered only a few domestic manufacturers' carbide have the field proven wear characteristics necessary when reaming tough abrasive materials.
2. Contrary to the machinery data handbook our design utilizes a smaller positive radial rake — for better performance when reaming steel.
3. Improved hole surface finish as this reamer's reduced circular land minimizes possible material buildup that will reduce surface quality.
4. Straighter holes because of longer full flute length carbide and reduced back taper. Many more regrinds before reinserting.
5. Controlled deep (- 300ºF) cryogenic treatment after the carbide is brazed on the tool — also several other subtle features that only our tools have.

OPTIONS

Intermediate decimal & metric sizes (priced as indicated in extended table below).

Radius end or end chamfer other than 45º.
End cutting.
Rose grind (twice normal back taper).
Semi-finished type reamers in stock.
Closer tolerance.
For +.0002" add $1.00 per tool.
For +.0001" add $3.00 per tool.
