Carbide Drills

AquaREVO Drills Burrless
Burrless series Reducing the burr at the exit of holes, and conical chips Thinning shape to reduce the hole expansion and corner shape to cut without leaving burrs. Excellent burrless performance on the cross hole which is difficult to deburring

AquaREVO Drills Micro
New lineup of small diameter sizes has been added while keeping the features of the “Long tool life”, “High efficiency”, and “Multipurpose” of the AquaREVO Drill series Achieves “long tool life that is hard to break” and “stable cutting with little dispersion” required for small-diameter drills. Newly developed carbide material has improved both hardness and toughness by original component design for micro drill. Achieves a drill that is hard to break with a flute shape that emphasizes rigidity and chip evacuation.

AquaREVO Drills Oil-Hole
Longer tool life by Overwhelming coolant amount New development Carbide Oil-Hole material As the second of AquaREVO series, developed "AquaREVO Drill Oil Hole". Optimized Oil-Hole geometry "REVO Power Cooler" adoption. Excellent function of Cooling, Lubrication and Chip evacuation by Fluid analysis. Apply for wide range material, such as Stainless steel to High hardened material.

AquaREVO Drills Stub / Regular / Semi-long
