Get the Job Done with Our Ultimate Tungsten Power Bit
Looking for a drill bit that can handle any surface? Our tungsten power bit is the answer. It effortlessly bores through steel, stone, concrete, metal, wood, and glass in record time, making it the perfect tool for any job.
Quad-Edge Saw-Tooth Point for Easy Drilling
Our bit features a solid tungsten-steel core with four scalpel-sharp faces that self-center instantly, biting clean and reducing walk and burrs on tough materials. This means you can drill with confidence and precision.
Violet Titanium Shield for Extended Life
The bold violet color isn't just for show - it's a sign of the Ti-Al-N armor that's fused to the tungsten steel, providing up to 3 times the life of bare HSS bits. This means you can drill more and replace less, saving you time and money.
Rapid Chip Clearance for Smooth Drilling
Our oversized twin-helix flutes carve wide airways, flinging debris clear and keeping the tungsten edge cool and razor-keen. This means you can drill faster and more efficiently, without worrying about overheating or clogging.
¼″ Hex Quick-Lock Shank for Secure Drilling
Our bit features a ¼″ hex quick-lock shank that clicks into impact drivers, cordless drills, or presses for slip-free, full-torque delivery. This means you can drill with confidence, knowing your bit is securely in place.
Five Core Diameters for Versatility
We offer five core diameters (6, 8, 10, 10L, and 12 mm) to cover pilot holes through heavy-duty anchors. Check out our full size chart below to find the perfect bit for your job.

Frequently Asked Questions
Do I need coolant when drilling glass or ceramic?
Yes, using coolant will help preserve the tungsten steel edges and prevent cracks.
Can these bits handle hammer action?
Our bits are engineered for rotary work, but they can handle light tapping on masonry.
Are the tips resharpenable?
Yes, the tungsten-steel edge can be touched up with a diamond wheel, although replacing the bit is often faster and more cost-effective.
