New Enhanced Insert Clamping Provides TungHeavyGroove with Higher Performance in Deep, Wide, and Heavy Grooving Operations

Iwaki, September 2023— Experience unmatched productivity and reliability in heavy-duty grooving and wide-profile grooving with Tungaloy’s TungHeavyGroove grooving inserts and toolholders. Our latest innovation introduces an enhanced insert clamping design, for maximum tool rigidity.

TungHeavyGroove indexable grooving tool line is developed for efficient heavy-duty grooving and wide profile grooving applications, offering inserts in widths of 10, 15, 20, and 25 millimeters.

New SHER-CHP toolholders incorporate unique durable features that enhance the tool reliability. Having a thick strong structure, the toolholder supports the insert underneath its cutting edge, contrary to the conventional toolholders, which offer no support directly under the cutting edge. This provides the insert with extra security in sustaining heavy cutting loads during machining. Our toolholders feature a reinforced design that may look unconventional but offers multiple contact faces. This design maximizes contact with the machine turret or tool post, resulting in significantly higher stability and rigidity compared to conventional toolholders. Generally in grooving, and particularly in deep grooving, the chip flow prevents the coolant from reaching the cutting edge. The new TungHeavyGroove toolholders utilize a frontal coolant system, delivering high-pressure cutting fluid from the bottom to the flank face of the cutting edge. This innovative design enhances chip evacuation and extends insert tool life significantly. Furthermore, an extremely rigid dovetail insert clamping method sustains heavy cutting loads during aggressive wide grooving and profile grooving, while providing process security.

Ten new inserts are introduced in total, including two geometries. HGM grooving inserts incorporate a pressed-in chip former and are available in versatile AH8015 grade or T9215 grade optimized for high speed machining of steel. HBL inserts are available as blanks so that users can tailor them into customer-specific groove forms of up to 6.6 millimeter (.260″) depth of cut. HBL is made from versatile TH10 uncoated carbide grade.

16 new square shank toolholders are introduced in both metric and imperial sizes with shank heights and widths of 25×25, 32×32, and 40×40 mm for metric sizes and 1″x1″, 1 ¼″x1 ¼″, and 1 ½″x1 ½″ for imperial sizes.
