Total TAC100403 HSS drill bit 4.0mm 10pcs

Convenient 10-Piece Bulk Pack: Offers multiple replacement bits for high-frequency operations like drilling rivet holes, pre-drilling screw pilot holes, and metal fabrication.

135° Split Point Tip: Prevents drill bit wander or “walking” on flat or curved metal surfaces, allowing accurate starts without a center punch.

Precision Ground Flutes: Polished spiral flutes rapidly clear metal chips and shavings to lower friction heat and extend bit life.

Universal Straight Shank: Fits standard 3-jaw keyed or keyless drill chucks on corded drills, cordless driver-drills, and bench drill presses.
