Tungaloy is expanding its insert line for TungSix-Drill, the head-changeable drill, to include grade AH3135. TungSix-Drill is an indexable insert drill that incorporates double-sided, triangular inserts with six effective cutting edges. Unlike traditional double-sided inserts, which would generate unwanted, heavy cutting load during drilling, the TungSix-Drill insert is designed with an optimized rake angle and chipbreakers on both sides of the insert, which provide the same light cutting action as a single-sided, positive insert.

AH3135 is a high fracture-resistant grade consisting of a tough carbide substrate and multiple layers of coatings designed to withstand high vibrations due to unfavorable cutting conditions ensuring long tool life.

Thanks to the insert's increased number of cutting edges and tool life, TungSix-Drill provides the most efficient cost-per-insert economy in Tungaloy's holemaking line.

At a glance:

Drill diameters: 0.812" – 2.000" (20 - 27 mm), 2xD, 3xD, and 4xD

Double-sided inserts with six fully usable cutting edges

Identical inserts used for both the center and the periphery

High hole-diameter accuracy due to the optimal insert positioning

Robust center cutting edge due to the most effective geometry

AH3135 grade for fracture resistance
