Kennametal 1599057 DNMG432MP1 KC5010 Carbide Turning Insert

Product Description

The KENNAMETAL 1599057 is a solid carbide turning insert carrying the industry standard designation DNMG432MP1 in the KC5010 grade. The insert features a physical vapor deposition (PVD) TiAlN coating engineered for high wear resistance across a range of workpiece materials, including steel, stainless steel, cast iron, and superalloys. It carries a 55-degree diamond (rhombic) shape, a 0.5-inch inscribed circle, a 0.03125-inch corner radius, and a neutral hand orientation. The MP1 chip breaker geometry supports consistent chip control during turning, facing, boring, back turning, and back boring operations. This insert is sold individually with a minimum order quantity of 5 units.

The 1599057 is suited for general and precision turning applications in CNC lathes and turning centers operating on steel and stainless steel components as its primary target materials, with additional capability on cast iron, aluminum, and titanium alloys. The KENLOC series designation indicates compatibility with KENNAMETAL KENLOC-style toolholders that accept DNMG-style inserts secured by clamp and pin holding methods. It is installed by machinists and CNC lathe operators in job shop, production, and aerospace supply-chain environments where consistent surface finish and tool life are required.

Key Features

• KC5010 PVD TiAlN coating delivers high wear resistance for steel, stainless steel, and cast iron applications
• 55-degree diamond (rhombic) insert shape with a 0.03125-inch corner radius for versatile profiling and finishing cuts
• MP1 chip breaker geometry supports turning, facing, boring, back turning, and back boring in a single insert
• Negative rake angle and negative side clearance (clearance code N) for maximum edge strength
• Four cutting edges per insert maximize cost per edge on the shop floor
• Honed cutting edge style reduces micro-chipping at entry and during interrupted cuts

Compatibility

Designed for use in KENNAMETAL KENLOC-series toolholders that accept DNMG432 (ISO: DNMG150408) inserts secured by clamp and pin holding. Verify toolholder pocket geometry, seat, and clamp compatibility before installation. The insert meets both ANSI and ISO dimensional standards for DNMG-style inserts.

Installation Notes

Installation is performed by a qualified machinist or CNC lathe operator. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten the clamp or the seating pin. Inspect the insert pocket and seat for chips or debris before seating the new insert, as contamination in the pocket affects edge height and finish quality.
