Kennametal 2244983 Turning Insert Vnmg K313 Carbide

Product Description

The KENNAMETAL 2244983 is a solid carbide, uncoated turning insert in the VNMG geometry designed for precision metal cutting operations. Carrying the ANSI designation VNMG3305MS and ISO designation VNMG160402, this insert features a 35-degree diamond (rhombic) shape with a negative rake angle and neutral hand orientation. The MS chip breaker geometry is engineered for roughing and medium machining applications. With a 0.3750-inch inscribed circle, a 0.0079-inch corner radius, and an insert length of 16.61 mm (0.6539 inches), it is suited for stable, high-wear-resistance cutting in a range of workpiece materials. Licensed HVAC techs and machinists working with CNC lathes and turning centers are the primary installers.

This insert is used in turning, facing, boring, back turning, and back boring operations on CNC and manual lathes. The K313 grade is characterized by high wear resistance to moderate wear resistance and toughness, making it appropriate for stainless steel (M), cast iron (K), and aluminum and non-ferrous (N) workpiece materials. The primary workpiece material codes are P, M, K, N, and S, which includes non-ferrous metals and superalloys and titanium. The KENLOC series insert seats into compatible toolholders using clamp and pin holding methods.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Always power down and lock out the machine before seating or indexing inserts. Use the appropriate torx or hex key to secure the clamping pin to the manufacturer-specified procedure; do not overtighten or use impact tools on insert screws. Inspect the insert pocket and seating surface for chips or damage before installing a new cutting edge.
