TRISTAR Drill Series

Feature of DVAS

Setting New Standards for 2-flute Drilling Accuracy

New XR Thinning

The self-centreing function provides excellent centripetal motion and ensures stable and accurate initial penetration when drilling flat surfaces.

New XR Thinning

Contact Pressure Comparison (simulation analysis)

DVAS provides stable contact pressure in a concentric pattern, thereby providing accurate positioning and minimises wandering during initial penetration.

Cylindricity Comparison

Its unique design allows for more precise hole processing than conventional two and three flute drills.

Cylindricity Comparison

Continuously Evolving Coolant Hole Geometry

TRI-Cooling Technology is applied to all sizes.
Chip removal and heat dissipation are improved, enabling stable and long tool life.

Continuously Evolving Coolant Hole Geometry

Straight Cutting Edge Reduces Damage

The straight main cutting edge and point thinning geometry are smoothly connected and therefore reduces the risk of abnormal damage.
