Taper reamers for installation of AN385 and AN386 aircraft taper pins. Straight shank, straight flute. High speed steel, material No. These are Browne & Sharpe Style Reamers.
Made in the USA
Bought this item to ream AN386 3-14 taper pin for RV-7A nose gear modification. I experience the same problem that others have reported on the forums. This just doesnt seem to cut at all even though I was careful to use plenty of cutting fluid and not abuse the tool. It never produced a single shaving despite various pressure and hand-turning techniques. Not sure if spruce got a bad batch or just needs to get another supplier. There are other manufacturers for Brown and Sharpe style tapers for half the price. This one gets 1 star.
