EXPANSION CHUCKING REAMERS — CARBIDE TIPPED

STRAIGHT FLUTE LONG CARBIDE & STRAIGHT SHANK

TYPE 2465 — STRAIGHT FLUTE LONG CARBIDE & STRAIGHT SHANK — FRACTIONAL SIZES

Expansion adjusting screw permits expansion of cutting diameter for regrinding after wear without reinserting carbide.
Straight shank and straight polished flutes.
Flute long carbide tips brazed to one piece hardened tool steel bodies.
Cutting diameter tolerance plus .0003" minus .000".

USE:

Expansion reamers are recommended for reaming abrasive materials and as the diameter wears down, the reamers can be expanded many times by tightening the end adjusting screw and regrinding to its original size. Because this procedure can be repeated several times, the expansion reamer is a very economical tool. Expansion reamers should not be expanded to use at diameters larger than listed diameters nor be considered as adjustable for use in producing holes of several sizes. The expansion screw should never be loosened.
