135-Degree Split-Point Drill Bit
This 23/64 inch jobber-length drill bit features a 135-degree split point for self-centering starts on hard materials. The high-speed steel body is coated with TiN to reduce friction and extend cutting life. It is designed for general-purpose drilling in metal, wood and plastic.
Best for single-hole precision work
Mechanics and fabricators who need accurate hole placement without centre-punching will benefit from the split-point geometry. Buyers who require coolant-through capability or multiple coolant holes for deep-hole production should look at other tooling.
TiN coating reduces wear and heat
The titanium nitride surface treatment lowers cutting temperatures and resists built-up edge on ferrous alloys. No additional accessories or software are bundled with this individual drill bit.

Questions about this item
What size drill chuck do I need to hold the 23/64 inch shank of this jobber length drill?
A chuck with a minimum capacity of 23/64 inch (0.3594 decimal) is required to secure the drill bit shank.
Will the 135-degree split point cut cleanly in the mild steel I usually drill with general-purpose bits?
The 135-degree split point is designed for heavy-duty drilling in harder materials and reduces walking on mild steel surfaces.
How can I confirm the TiN coating is intact and the split point is centered before I start drilling?
Inspect the gold-coloured TiN coating for uniform coverage and verify the split point appears symmetrical at the tip.
