LEFT SPIRAL FLUTES & STRAIGHT STEEL SHANK

TYPE 2820 – FINISHED FRACTIONAL SIZES

Solid carbide head.
Straight steel shank on .1911" tool diameter and larger (smaller sizes have a straight solid carbide shank).
Tool diameter tolerance thru .2500": plus .0002", minus .0000".
Tool diameter tolerance over .2500": plus .0003", minus .0000".
