CENTER REAMERS<br />
(SHORT COUNTERSINKS 3-FLUTE)<br />
Designed for counter sinking holes for centers or for enlarging existing hole<br />
Odd number of flutes eliminates chatter in most applications, while<br />
providing better accuracy than a single flute countersink<br />
Available in 60°, 82° or 90°<br />
Made from high speed steel<br />
Manufacturing specifications:<br />
