Micro Stop Countersink - Carbide - 2-3-4 Flute (request) - Pilot Range (request) - 90 Deg - 3/8 X .0938-.1285 X 1/4-28

3/8" body 90° micro stop countersink, 1/4-28 thread.

A micro stop countersink screws into a micro stop cage, which sets the depth mechanically so every seat comes out the same — the standard way of countersinking for flush fasteners in aerospace work. The cutting body is 3/8" at a 90° included angle, on a 1/4-28 mounting thread.

It takes pilot pins from .0938 to .1285", so one cutter covers a range of hole sizes: change the pilot, not the tool.

Available in 2, 3 or 4 flutes and other pilot ranges on request.
