PATIKIL 3mm Hex Shank Drill Bit Set – 6-Pack M2 HSS Bits With Titanium Nitride Coating, 135° Split Point For Impact Drivers & Stainless Steel

About This Product

These little 3mm drill bits are absolute troopers when it comes to drilling into tough metals.

They're made from M2 high-speed steel, so they stay sharp and resist wear even when you're pushing through stainless steel, cast iron, or alloy steel.
The titanium nitride (TiN) coating isn't just for show—it cuts down on friction, prevents corrosion, and helps the bits last way longer than uncoated ones.

The hex shank is 1/4 inch, which means they lock securely into any quick-change chuck, impact driver, or standard drill.

No slipping, no wobbling—just a solid grip that keeps your holes straight and accurate.

The 135° split point tip starts drilling immediately without wandering, so you don't have to center-punch every single hole.

Each bit has a 33mm flute length and an 82mm overall length, giving you good reach for most jobs.

This 6-pack gives you plenty of spares, which is nice because 3mm bits tend to disappear or break if you're not careful.

For best results, keep the drill at a 90° angle to the workpiece, use cutting fluid for tough materials, and drill in steps for thicker stock.

These bits are a solid choice for any workshop—reliable, sharp, and they get the job done without fuss.
