Kennametal 4177656 Milling Insert K115M Solid Carbide Ball Nose

Product Description

The KENNAMETAL 4177656 is a solid carbide ball nose milling insert carrying the ANSI/ISO designation KDMB1000M0ERLD and manufactured to grade K115M. Designed for indexable milling cutters in the KDMB series, this insert delivers a 0.5000-inch corner radius and a maximum depth of cut of 0.5000 inches. The bright/uncoated finish is appropriate for applications where coating is not required or where sharp, honed cutting edges are the priority. Weighing 0.143 pounds, the insert measures 1 inch wide and 1 inch long with a thickness of 0.1575 inches. It features a positive rake angle of 15 degrees and a relief angle of 15 degrees. Installation is performed by licensed machinists and CNC tooling technicians.

This insert is suited for milling cast iron, non-ferrous metals, superalloys, and titanium. The LD chip breaker geometry is optimized for these material groups, making it a practical choice for aerospace, automotive, and general precision machining environments. The right-hand cut orientation and screw-holding method are standard for KDMB-series cutter bodies. The double-sided configuration and single cutting edge per side reflect the ball nose geometry requirements for full-radius profiling and contouring operations in production and job-shop settings.

Key Features

• Ball nose insert geometry with 0.5000-inch corner radius for full-radius profiling and contouring
• Solid carbide K115M grade - uncoated, bright finish with honed cutting edge
• Positive rake angle (15 degrees) and 15-degree relief angle for reduced cutting forces
• LD chip breaker designed for cast iron, non-ferrous metals, superalloys, and titanium
• Right-hand cut, screw-held mounting compatible with KDMB cutter series
• Complies with ANSI and ISO insert standards (ANSI/ISO code: KDMB1000M0ERLD)

Compatibility

Designed for use with KENNAMETAL KDMB-series indexable milling cutter bodies. The ANSI/ISO code KDMB1000M0ERLD and insert size code 1000 define the compatible cutter seat geometry. Verify cutter body pocket specifications before ordering.

Installation Notes

This insert is installed and replaced by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before removing or seating any indexable insert. Use the appropriate Torx or hex key to seat the clamping screw to the cutter body manufacturers specified torque - do not over-tighten or substitute fasteners. Inspect the cutter pocket and screw threads for wear or debris before installing a new insert.
