Kennametal 1505366 Ceramic Milling Insert SPHX1205ZCTR-GP1WK

Product Description

The KENNAMETAL 1505366 is a single-sided, square ceramic milling insert using the ANSI and ISO designation SPHX1205ZCTR-GP1WK in the KY3500 micrograin ceramic grade. It is uncoated and carries a bright finish, suited for high-speed dry or near-dry milling operations. The insert measures 0.394 inches in length and 0.217 inches thick, with a 0.217-inch inscribed circle and a 0.197-inch mounting hole diameter. A positive rake geometry and T-Land cutting edge style help manage cutting forces. The GP chip breaker geometry is optimized for cast iron applications. Licensed CNC machinists and tool crib technicians install and index these inserts as part of scheduled tooling maintenance on milling machines.

This insert is designed for milling cast iron workpieces, classified under primary workpiece material code K. It fits the Fix-Perfect cutter series and is held in place by a screw-clamping method. The positive rake and 11-degree relief angle reduce cutting pressure on brittle cast iron structures. With a maximum depth of cut of 0.259 inches, it is suited for finishing and semi-finishing passes on gray iron, ductile iron, and similar cast iron grades in both job-shop and production environments.

Key Features

• KY3500 micrograin ceramic grade engineered for cast iron milling
• Uncoated bright finish — no thermal coating processes applied
• Positive rake with T-Land cutting edge for controlled chip formation in brittle materials
• GP chip breaker geometry optimized for cast iron application
• Single-sided insert with one cutting edge; right-hand orientation
• Screw-mount retention compatible with Fix-Perfect cutter bodies

Compatibility

Designed for use in Fix-Perfect series milling cutter bodies that accept SPHX1205 insert geometry with screw-mount retention. Conforms to ANSI and ISO standards under the SPHX1205ZCTR-GP1WK designation.

Installation Notes

Insert indexing and replacement should be performed by a qualified CNC machinist or tooling technician with the spindle fully stopped and machine in a locked-out, tagged-out state per applicable safety procedures. Use the correct Torx or hex key driver at the manufacturer-specified torque for the screw-retention system — do not overtighten or use impact tools on insert screws. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Confirm correct orientation for right-hand cutting direction before resuming operation.
