Solid Cobalt 6-Step Drill Bit 3/16-1/2" Quick-Change Hex Shank
Product Description
Solid Cobalt 6-Step Drill Bit 3/16-1/2" Quick-Change Hex Shank
- Heavy-duty cutting power for the toughest metals like hardened steel, stainless steel & titanium
- Solid Cobalt steel alloy - not coated like others - dissipates heat faster, stays sharp longer
- Lasts up to 4-times life of HSS or titanium coated bits; can be resharpened for even longer life
- Like 6-bits-in-1, drills holes from 3/16" to 1/2" in 1/16" steps with faster penetration
- Unique hex shank won't slip in chuck, quick-change style fits impact drivers, bit holders/extensions
Step drill bits are a wise investment for professional & do-it-yourself handymen and this Cobalt version is an excellent value. Drilling is more efficient - especially in hard steel - because the hole is cut in increments, with less stress on the bit, drill/impact driver and operator. Unlike regular, round shanks the hex quick-change shank works in quick-change bit holders and popular small form-factor drills & impact drivers that have bit sleeve instead of chuck. 3" length overall, weight 1.5 oz. PLEASE NOTE: the brass-colored coating on this bit is for identification purposes and wears off with use. Since the composition is solid Cobalt steel alloy, loss of the coating does not impact cutting efficiency or durability.
