Kennametal 1198162 Turning Insert VBMT33111 KT325

Product Description

The KENNAMETAL 1198162 is a VBMT33111 KT325 cermet turning insert designed for precision metal cutting on CNC lathes and turning centers. It features a 35-degree diamond insert shape with a neutral hand orientation and a positive rake angle of 5 degrees. The inscribed circle measures 0.375 inches, the insert length is approximately 1.308 inches (16.61 mm), and the corner radius is 0.0156 inches (1/64 inch). The cutting edge is honed and uncoated, making this a bright cermet grade suited for finishing and semi-finishing operations. Screw-on holding method secures the insert firmly in compatible toolholders. Qualified machinists and CNC operators install and index this insert during production turning work.

This insert is suited for turning, facing, boring, back turning, and back boring operations on steel and cast iron workpieces. The KT325 cermet grade performs well in finishing cuts where surface finish consistency and edge sharpness are priorities. The uncoated cermet substrate provides low friction against the workpiece and resists built-up edge at moderate cutting speeds. It carries material grade designations C3, C4, C7, and C8, and meets both ANSI and ISO standards. The ISO code for this insert is VBMT160404 11, and the industry standard number is VBMT33111. This insert is packaged individually but carries a minimum order quantity of 5 units.

Key Features

• 35-degree diamond insert shape (Shape Code V) with 2 cutting edges for index efficiency
• Uncoated KT325 cermet grade optimized for finishing and semi-finishing on steel and cast iron
• Positive rake angle (5 degrees) and honed cutting edge reduce cutting forces and improve surface finish
• Screw-on insert holding method for rigid, repeatable seating in the toolholder pocket
• Neutral hand orientation allows use in a wide range of turning setups
• Compliant with ANSI and ISO insert standards for broad toolholder compatibility

Compatibility

Designed as a screw-on style replacement insert for VBMT-style toolholders accepting a 3/8-inch inscribed circle, 35-degree diamond insert. Compatible with toolholders conforming to ANSI and ISO VBMT insert pocket specifications. Verify toolholder pocket geometry, screw bore diameter (0.1732 inches), and insert thickness (0.1875 inches) before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque; do not overtighten, as cermet inserts are brittle and can fracture under excessive clamping force. Inspect the toolholder pocket and seating surface for debris or wear before seating the new insert.
