Wescon 1605 1/4‑28 Threaded Drill Collet - Size 0.0970in
Product details
WES1605 threaded drill collets thread into a 1/4-28 threaded angle drill or pancake drill attachment and let it run standard round shank tools such as drill bits, reamers, countersink cutters and deburring cutters. The 120 degree seat matches the spindle of most aircraft angle drills, so the collet seats square and the tool runs true.
Fourteen stock sizes cover wire gauge, letter, fractional and decimal sizes from #50 (0.070 in) to F (0.257 in), including #40, #30, #20, #10, 3/16 in and 1/4 in. The 1/4 in collet, WES1605-2500, fits the many bits and cutters made with a 1/4 in shank. Pick the collet for the shank you run, thread it into the spindle, insert the shank and tighten the collet nut with a wrench. Custom sizes are available as an option on the product page. Made in USA.
