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.

Five Core Diameters
6 / 8 / 10 / 10L / 12 mm cover pilot holes through heavy-duty anchors—see the full size chart below.


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.
