Kennametal 1732928 Cutoff Insert KC5025 Carbide 3mm

Product Description

The KENNAMETAL 1732928 is a carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Built to the A2 insert style with a KC5025 manufacturer grade, this insert features a TiAlN coating applied via PVD process, which provides thermal resistance and edge durability in demanding interrupted and continuous cuts. The 3 mm cutting width (0.1181 inches) and 0-degree neutral lead angle make it well-suited for straight, square-shoulder cutoff work. A CM chipbreaker geometry controls chip flow and reduces cutting forces. Machinists and toolroom technicians select this insert for reliable performance in production environments.

The 1732928 insert is intended for cutoff and parting applications on ferrous and non-ferrous metals in both production and job-shop turning setups. The A2 series insert seat size 3 configuration fits compatible KENNAMETAL toolholders and blade systems designed for A2-style inserts. It is appropriate for applications requiring precise groove widths, facing cuts, and part-off operations on bar stock, tubing, and turned components.

Key Features

• Carbide substrate with KC5025 grade for wear resistance in turning and parting operations
• TiAlN PVD coating for elevated heat resistance and extended tool life
• 3 mm (0.1181 inch) cutting width for accurate groove and cutoff dimensions
• CM chipbreaker geometry for controlled chip evacuation
• Neutral (0-degree) lead angle for square, burr-minimized cutoff profiles
• 2-degree relief angle reduces rubbing and flank wear

Compatibility

Designed as an OEM-style replacement insert for A2 series insert toolholders and blade systems accepting an insert seat size 3 with a 3 mm cutting width.

Installation Notes

Cutoff inserts of this type are installed and replaced by machinists or toolroom technicians following machine-specific lockout and spindle-stop procedures before any toolholder access. Ensure the insert pocket and clamping surfaces are clean and free of chips before seating the insert. Clamp retention must be confirmed secure before resuming cutting operations. Consult the toolholder manufacturer torque and clamping guidelines for proper insert seating.
