One Bit, Any Surface — Blaze Through Jobs with Tungsten Power
Bore through steel at dawn, then glide through porcelain by noon—the same tungsten-steel bit crushes stone, concrete, metal, wood & glass in record time.
Quad-Edge Saw-Tooth Point
A solid tungsten-steel core capped by four scalpel-sharp faces self-centers in an instant, biting clean to curb walk and burrs on brutal materials.
Violet Titanium Shield
The bold hue isn’t paint—Ti-Al-N armour fuses to tungsten steel, shrugging off heat to deliver up to 3× the life of bare HSS.
Rapid Chip Clearance
Oversized twin-helix flutes carve wide airways, flinging debris clear so the tungsten edge stays cool and razor-keen.
¼″ Hex Quick-Lock Shank
Clicks into impact drivers, cordless drills or presses for slip-free, full-torque delivery.

FAQ
Do I need coolant when drilling glass or ceramic?
Yes—steady water flow preserves tungsten steel edges and prevents cracks.
Can these bits handle hammer action?
They’re engineered for rotary work; light tapping on masonry is acceptable.
Are the tips resharpenable?
The tungsten-steel edge can be touched up with a diamond wheel, though replacing is often faster and cost-effective.
