Kennametal 4168860 Indexable Cutoff Toolholder Left Hand

Product Description

The KENNAMETAL 4168860 is a left-hand indexable cutoff toolholder designed for parting and grooving operations on CNC lathes and turning centers. It accepts A4G0200M02P02B inserts with a 2 mm minimum insert width and delivers a maximum depth of cut of 14.5 mm (0.571 inches). The toolholder features a 1/2 x 1/2 inch shank and an overall length of 4.5 inches (114.3 mm), making it a compact, rigid option for light to medium turning work. Machinists and CNC operators working with workpieces up to 28 mm (1.102 inches) in diameter will find this holder well-suited to precision cutoff applications.

This toolholder is intended for use on lathes and turning centers where left-hand cutoff or grooving work is required. It belongs to the A4 series and uses the A4SC toolholder style, which is suited for bar work and production turning environments. The 1/2 x 1/2 inch shank fits standard lathe tool blocks and quick-change toolpost holders commonly found in both manual and CNC turning setups. No coolant-through capability is included, so external coolant delivery should be planned accordingly.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician.

Seat the shank fully in the tool block and verify clamping torque against the machine tool manufacturer specifications before running. Confirm insert seating and clamp integrity before initiating any cutting cycle.
