Kennametal 1222101 Milling Insert Solid Carbide Uncoated

Product Description

The KENNAMETAL 1222101 is a solid carbide milling insert designed for precision metal removal in milling operations. Manufactured to ISO code 4.21103R611, this insert features an irregular shape with a right-hand orientation and a positive rake geometry. It is uncoated (bright finish), making it well suited for applications where coating-induced edge buildup would reduce cutting performance. At 0.158 inches thick with a 0.5906-inch inscribed circle and a length of 0.4134 inches, this insert is a compact, high-rigidity cutting tool intended for use by machinists and tool-and-die technicians in production and job-shop environments.

This insert is rated for use in cast iron and non-ferrous metal workpiece materials, corresponding to ISO material groups K and N. The positive rake geometry reduces cutting forces, which is particularly advantageous when machining softer non-ferrous alloys or when machine spindle rigidity is limited. It is held in the toolholder via a screw-clamping method, common in modern indexable milling systems. This insert is sold individually but requires a minimum order of 5 units.

Key Features

• Solid carbide construction in manufacturer grade K110M for wear resistance in K and N material groups
• Positive rake geometry reduces cutting forces on cast iron and non-ferrous workpieces
• Right-hand, single-sided insert in irregular shape per ISO style 4.21103R611
• Bright/uncoated finish eliminates coating variables for consistent edge performance
• Screw-held mounting method compatible with indexable milling toolholders
• Inscribed circle of 0.5906 inches and thickness of 0.158 inches for compact milling applications

Compatibility

Designed as an OEM-style indexable milling insert for toolholders accepting ISO 4.21103R611 style inserts with a screw-clamp holding method and a right-hand orientation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified torque — do not over-tighten, as this can fracture the carbide. Inspect the insert pocket and seating surface for chips or debris before seating the insert.
