High Quality 4-Piece Purple Drill Bit Set

Get the Job Done Faster with Our Tungsten Power Bits

Take your drilling to the next level with our powerful tungsten-steel bits. They make it easy to drill through tough materials like steel, porcelain, stone, concrete, metal, wood, and glass, saving you time and effort. With our bits, you can complete your projects quickly and efficiently.

 

 

Quad-Edge Saw-Tooth Point for Easy Drilling

Our bits feature a solid tungsten-steel core with four sharp edges that self-center instantly, making it easy to drill clean holes in tough materials without burrs or walk. This means you can achieve professional-looking results without the hassle.

 

 

Violet Titanium Shield for Long-Lasting Performance

The unique violet color of our bits is not just for show - it's a result of our Ti-Al-N armor that's fused to the tungsten steel, providing up to 3 times the life of regular HSS bits. This means you can drill more holes without needing to replace the bit, saving you time and money in the long run.

 

 

Rapid Chip Clearance for Smooth Drilling

Our bits feature oversized twin-helix flutes that quickly remove debris, keeping the tungsten edge cool and sharp. This means you can drill faster and more efficiently without worrying about the bit getting clogged or damaged.

 

 

¼″ Hex Quick-Lock Shank for Easy Attachment

The ¼″ hex quick-lock shank makes it easy to attach the bit to your impact driver, cordless drill, or press, providing a secure and slip-free connection. This means you can start drilling right away, without worrying about the bit coming loose.

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, ensuring a longer bit life and better results.

Can these bits handle hammer action?
Our bits are designed for rotary work, but you can use them for light tapping on masonry. However, for heavy hammering, we recommend using a dedicated hammer bit.

Are the tips resharpenable?
You can touch up the tungsten-steel edge with a diamond wheel, but replacing the bit is often faster and more cost-effective. This way, you can get back to work quickly and avoid downtime.
