DVAS

Setting New Standards for 2-flute Carbide Drills
Hole quality comparable to 3-flute drills

TRISTAR Drill Series

High Precision - Process Saving - Long Tool Life

TRISTAR, a new generation drill series from Mitsubishi Materials provides 3 strong advantages.

The second of the Tristar series is a medium diameter drill with 5 technological features for High Precision, Process Saving and Long Tool Life drilling.

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.

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.

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.

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.

S50C : Comparison Tool Life

The combination of a hard grade substrate, optimum edge geometry and high precision, tool life has been extended by 150%.
