★ What Is a Hex Shank Drill Bit?

A hex shank drill bit replaces the standard round shank with a six-sided one that locks directly into quick-change chucks — the kind found on cordless screwdrivers and impact drivers, not just standard three-jaw drill chucks. The flat faces of the hex give the chuck a positive mechanical grip instead of relying on clamping friction alone, so the bit resists spinning in place even under the sudden torque spikes an impact driver produces. In practice, this means one tool can switch between driving screws and drilling pilot holes in seconds, without swapping chucks or reaching for a key — a real time saver on job sites and production lines where the same operator handles both tasks repeatedly through a shift.

★ Why Titanium Nitride (TiN) Coating?

Titanium nitride is a thin and hard layer applied to the surface of the HSS bit after grinding. It does two things at once. Functionally, it raises the surface hardness of the cutting edge and lowers the coefficient of friction between the bit and the material being cut, so the edge runs cooler and chips slide off the flutes more easily during the cut. This translates into less edge wear per hole and more consistent cutting action over a longer service life compared to an uncoated bit of the same base steel. Cosmetically, the coating gives the bit its distinctive gold finish, which also makes it easy to visually distinguish from uncoated stock in a mixed toolbox or bin — useful for shops running multiple bit types side by side.

★ Primary Applications
The combination of hex shank convenience and titanium-coated cutting performance makes this bit suited to environments where speed of changeover matters as much as drilling performance itself:

• Construction and job-site work — framing, fixture installation, and general fabrication where operators switch constantly between driving and drilling
• MRO and maintenance — quick pilot holes and repair work using the same impact driver already on hand
• Field service and installation — electrical, HVAC, and equipment installation where portability and tool-count reduction matter
• General metal fabrication — mixed-material shops needing a reliable, general-purpose bit for steel, aluminum, and other common alloys
• Automotive and light industrial assembly — repetitive drilling tasks where cordless tool compatibility speeds up the workflow

★ Material, Shank & Packaging Options

Material — Available in HSS-M2 for general-purpose drilling in mild steel, aluminum, wood, and plastic, or HSS-M35 (cobalt) where the workpiece includes stainless steel or other tough, heat-generating materials and the cobalt content is needed to hold edge hardness under sustained heat.
Shank Type — Hex shank across the full diameter range, so the entire size set shares the same quick-change compatibility regardless of cutting diameter.
Coating — Titanium nitride (gold finish) standard; black oxide or bright finish available on request for buyers who prefer a different surface treatment.
Packaging — Single size, full metric sets, or OEM/private label packaging available — contact us with your volume and specification requirements.
