Kennametal 4045206 CCMT3252FW KCU10 Turning Insert

Product Description

The KENNAMETAL 4045206 is a solid carbide turning insert designated CCMT3252FW in the ANSI system and CCMT09T308FW under ISO. It carries the KCU10 manufacturer grade with a PVD-applied TiAlN coating engineered for high wear resistance across a range of workpiece materials. The insert features an 80-degree diamond (rhombic) shape, a neutral hand orientation, and a wiper finishing chip breaker geometry (FW) that promotes superior surface finish at higher feed rates. With a 0.3750-inch inscribed circle and a 1/32-inch (0.0313-inch) corner radius, it is suited to light-to-moderate finishing passes. Installation is by screw-on (screw holding method). Two cutting edges are available per insert.

This insert is intended for turning, facing, and boring operations on CNC lathes and turning centers in production or job-shop environments. Primary workpiece materials include steel (P), stainless steel (M), superalloys and titanium (S), and cast iron (K), with secondary applicability to non-ferrous (N) and hardened materials (H). The wiper edge design makes it a practical choice when finish-turning requirements are tight and repositioning for a second finishing pass is not desirable. Licensed machinists and CNC turning specialists are the primary installers of this tooling.

Key Features

• KCU10 grade with PVD TiAlN coating for high wear resistance on steel, stainless steel, and superalloys
• 80-degree diamond insert shape (Code C) with positive rake and positive side clearance for reduced cutting forces
• Wiper finishing chip breaker (FW) delivers improved surface finish at standard finishing feed rates
• Screw-on holding method for secure, repeatable seating in compatible toolholders
• Two usable cutting edges per insert
• Honed cutting edge style reduces micro-chipping on interrupted and continuous cuts
• Complies with ANSI and ISO insert standards for broad toolholder compatibility

Compatibility

Designed to seat in CCMT-style screw-on toolholders accepting an ANSI size code 3252 (ISO 09T308) insert. Compatible toolholder bores require a 0.1732-inch hole diameter. Multi-use application covers turning, facing, and boring operations. Material grade classifications C3 and C4 apply.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Before changing inserts, confirm the machine spindle is fully stopped, the program is paused, and all axis motion is locked out per the machine tool manufacturer lockout/tagout procedure. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer specification — do not overtighten, as this can fracture the insert or damage the seat. Inspect the toolholder pocket and locating surfaces for chips or debris before seating a new insert.
