FRACTIONAL TYPE 3467 - TAPER SHANK - STRAIGHT FLUTE LONG CARBIDE
TYPE
Flute long carbide tips brazed to one piece hardened alloy steel bodies. Straight polished flutes.
Designed and manufactured for maximum tool life. 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. Expansion reamers should not be considered as adjustable for use in producing holes of several sizes.
