KEYSTONE ADJUSTABLE REAMER 1-3/16" - 1-11/32" USED
Not intended for high production work.
Designed for hand use only.
The blades are held in tapered slots by an adjusting nut on either end. To
adjust, loosen one nut and tighten the other, moving the blades up or down the
slot as needed. Do not overtighten, the slots and threads are easily damaged. To
measure size, adjust to a known size bushing or ring, or measure across two
opposite blades with a micrometer.
Suggestions for Use:
Adjust reamer size as needed. Mount the workpiece securely. Attach a tap
wrench to the reamer's square shank. Align the reamer and begin turning
(clockwise for right hand cut reamers). Apply even pressure while turning. Using
a cutting fluid will improve the surface finish and prolong reamer life.
Do not turn the reamer backward even when removing it from the hole.
Do not attempt to cut too heavily. .002-.005" per pass is typical.
