3/16" Cobalt Jobber Drill Bit
This 3/16 inch cobalt jobber drill bit handles tough metal drilling tasks. The split point design with a 135 degree angle reduces walking and starts holes cleanly. TiN coating adds wear resistance for extended tool life. It suits mechanics and fabricators working with stainless steel or hardened alloys.
Split Point & TiN Coating Benefits
The 135 degree split point centres the bit instantly without a centre punch. Cobalt construction withstands high heat generated in hard materials. TiN coating lowers friction and resists edge breakdown during repetitive drilling. The fractional size matches common fastener clearance charts.
Highlights

Questions about this item
Will the cobalt material or TiN coating wear off and require replacement of the 3/16" drill bit?
Cobalt is alloyed through the full body of the bit, so the heat-resistant properties remain after resharpening; the TiN surface coating will gradually wear with use but does not affect the core material.
What limit appears first when drilling continuously with the 135° split-point geometry?
Heat buildup in the workpiece and bit is the primary limit; the 135° split point reduces thrust and wandering, yet sustained high-speed drilling without coolant will still generate enough heat to dull the edge.
