Industrial 1/4" Hex Combination Drill and Tap Bit Set (Titanium, M3-M10)

Why buyers pick this one

3-in-1 Functionality

The self-centering split point drills the hole, the spiral flutes tap the thread, and the tapered shoulder countersinks the edge. This eliminates the need to constantly switch between drill bits and hand taps, saving immense labor time.

Titanium Nitride (TiN) Coating

The striking gold finish isn't just for show. The TiN coating significantly reduces friction and prevents chips from welding to the cutting edge, allowing the tap to run cooler and last longer. (Also available in uncoated bright finish).

1/4" Quick-Change Shank

Perfectly integrated with the modern contractor's workflow. The hex shank snaps instantly into impact drivers and magnetic bit holders, ensuring zero spin-out under load.

Complete Metric Coverage

Includes precision-milled pitches for M3x0.5, M4x0.7, M5x0.8, M6x1.0, M8x1.25, and M10x1.5, covering all standard electrical and structural panel fasteners.

Optimized for Sheet Metal

Engineered specifically for tapping through-holes in soft metals and thin-gauge materials (up to 3mm), preventing tap breakage commonly seen with improper application.
