PRODUCT DETAILS

WES1605 threaded drill collets screw onto a 1/4-28 threaded angle drill motor and let it run standard straight shank drill bits. The 120 degree seat matches the spindle of most aircraft angle drills, so the collet seats square and the drill runs true.

Fourteen sizes cover wire gauge, letter and fractional drills from #50 (0.070 in) to F (0.257 in), including #40, #30, #21, #10 and 1/8 in. Pick the collet for the drill diameter you run, thread it onto the motor, insert the bit and tighten. Custom bore sizes are made to order for drills outside the stock range. Made in USA.
