Cobalt Drill Bit 3/32"
Makes 3/32" hole for a flopper (barb) pin
For use with the Speardiver drill jig. Easily cuts through hardened spring stainless steel shafts.
* The cobalt drill bit will not work on coated South African carbon steel shafts like Rob Allen. These shafts require a %100 carbide bit. Carbide bits are very brittle and not practical for use with stainless steel shafts, that don't require carbide drill bits anyways.
