M35 Cobalt Steel Drill Bit 5/16"

The M35 Cobalt Steel drill bits are made of M35 grade steel alloy with cobalt. The cobalt increases the strength of the steel and makes it more heat-resistant.  Perfect to have in your toolbox when drilling horseshoes to add corks or plugs for traction. If you are using 3/8" threaded studs, use these 5/16" bits to drill holes in your shoes, then tap with a 3/8" tap.

• 135 Degree self-centering split point to help remove steel
• High flow spiral design bit body for fastest removal rate
• Straight shank for a standard drill chuck, end of the shank is chamfered to allow easy and firm holding
• Special bronze SST heat and surface treatment
