Kennametal 3377202 Modular Grooving Head KM16 A4S Insert

Product Description

The KENNAMETAL 3377202 is a modular grooving head designed for precision grooving operations on CNC turning centers and modular tooling systems. Built to KM16 system size, this right-hand cutting head accepts A4S inserts from the Micro A4 series and delivers a maximum depth of cut of 0.6299 inches (16.00 mm). The minimum groove width starts at 0.0787 inches (2.00 mm), making it well-suited for tight, close-tolerance grooving work. Licensed machinists and tooling technicians install this head as part of a modular quick-change setup, reducing changeover time while maintaining repeatable cutting geometry.

This cutting head is intended for use in modular grooving tooling assemblies operating on CNC lathes and turning centers that accept the KM16 interface. It is part of the Kennametal Micro A4 series, which targets small-diameter and fine-pitch grooving applications common in precision machining of aerospace, medical, and general metalworking components. The 0.3937-inch (10.00 mm) center-to-cutting-edge measurement and 1.1811-inch (30.00 mm) head length projection are critical reference dimensions when programming tool paths or selecting a compatible boring bar or toolholder body.

Key Features

• KM16 modular interface for quick, repeatable head changes on compatible toolholders
• Right-hand cutting direction for standard OD and ID grooving operations
• Maximum depth of cut of 0.6299 inches (16.00 mm)
• Minimum groove width of 0.0787 inches (2.00 mm) for fine-pitch grooving
• Accepts A4S insert style from the Micro A4 series
• Head length projection of 1.1811 inches (30.00 mm) for precise tool-path programming reference

Compatibility

Designed for use with KM16 modular tooling bodies that accept Micro A4 series grooving heads and A4S style inserts. Specific compatible toolholder bodies were not provided in available product data.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with modular quick-change tooling systems. Disengage machine power and confirm the spindle is fully stopped before mounting or removing the grooving head. Follow the toolholder manufacturer's clamping and torque procedures for the KM16 interface to ensure secure seating and repeatable tool position. Verify insert style and orientation before resuming cutting operations.
