Kennametal 3377201 Modular Grooving Head KM16 Left Hand

Product Description

The KENNAMETAL 3377201 is a modular grooving head designed for precision grooving operations in metalcutting applications. Configured for left-hand cutting direction, this component functions as the cutting head in a modular tooling assembly and mounts to the KM16 system interface. It accepts A4S inserts from the Micro A4 series, delivering a maximum depth of cut of 0.6299 inches (16.00 mm) and a minimum groove width of 0.0787 inches (2.00 mm). The head length projection measures 1.1811 inches (30.00 mm), and the center-to-cutting-edge distance is 0.3937 inches (10.00 mm). This tooling component is installed by machining professionals and toolroom technicians on CNC turning or grooving equipment.

The 3377201 is suited for external grooving applications in production and job-shop environments where modular quick-change tooling systems are in use. Its KM16 system interface makes it compatible with corresponding KM16 modular tool bodies. The left-hand cutting configuration is selected when workpiece orientation, spindle rotation, or machine setup requires cutting in that direction. Coolant-through capability is not provided on this head. Typical applications include part-off operations, undercut grooving, and profile grooving on lathes and multi-task machines running the Micro A4 system.

Key Features

• Left-hand cutting direction for dedicated left-hand grooving setups
• KM16 modular system interface for quick, repeatable head changes
• Accepts A4S inserts from the Micro A4 series
• Maximum depth of cut: 0.6299 inches (16.00 mm)
• Minimum groove width: 0.0787 inches (2.00 mm)
• Head length projection of 1.1811 inches (30.00 mm) for reach into tight clearance zones

Compatibility

Designed for use with KM16 modular tool bodies and compatible with A4S inserts in the Kennametal Micro A4 grooving series.

Installation Notes

Installation of modular grooving heads should be performed by qualified machining personnel with the machine powered down and the spindle fully stopped before any tooling changes. The KM16 modular interface requires proper seating and torquing of the clamping mechanism per the tooling system specifications. Verify insert orientation and cutting direction match the programmed tool path before resuming operation. Inspect the insert pocket and seating surfaces for chips or debris before mounting the head.
