Inserts’ Smaller IC Reduces Carbide, Increases Productivity

Ingersoll has added two insert styles to its T-Tank product line: the WNMX and DNUX inserts. T-Tank line inserts offer the same thickness and geometry as their larger parents but with smaller inscribed circle (IC) sizes, which translates to less carbide and greater productivity at reduced cost, the company says.

The WNMX trigon-shaped inserts offer six cutting edges with a 0.187" thickness. Each insert is said to provide improved stability compared to existing WNMG inserts with the same IC, providing longer, more consistent tool life, particularly in applications with interrupted cuts. The combination of increased surface contact area and strong hook lever clamping provide high stability and performance, the company says.

The DNUX inserts feature a high positive rake and inclination angle at the cutting edge said to minimize the radial and axial cutting forces that can cause vibration during machining, particularly in long, slender workpieces and in applications where a tailstock or steady rest is not utilized. The result is a more consistent surface finish and tool life compared to ISO-DNMG style inserts, Ingersoll says. The inserts offer four cutting edges and are compatible with the company’s existing T-Tank holders for DNMG inserts.
