Kennametal 2263186 Grooving Cutoff Toolholder Series A4

Product Description

The KENNAMETAL 2263186 is an indexable grooving and cutoff toolholder designed for external turning operations on CNC lathes and turning centers. Built to Series A4 standards, it accepts A4..08.. insert styles and uses a clamp-style insert holding method for secure, repeatable seating under interrupted cuts and continuous grooving passes. The shank measures 1 inch by 1 inch in cross-section with an overall length of 6 inches, and the toolholder is configured for right-hand operation. Minimum groove width is 0.315 inches (8 mm) and maximum depth of cut reaches 0.94 inches (24 mm), making it suitable for a wide range of grooving and parting applications in production environments.

This toolholder is intended for use in shops performing external grooving, cutoff, and profile turning on ferrous and non-ferrous workpieces. It is typically installed on production lathes and CNC turning centers where precise groove geometry and repeatable insert indexing are required. Machinists and toolroom technicians working in job shops, manufacturing facilities, and production turning cells will find the Series A4 platform a straightforward fit for medium to heavy grooving work. Coolant-through capability is not present on this holder, so external coolant delivery should be used when thermal management is needed.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out per facility lockout-tagout procedures. The shank should be clamped securely in a matching 1-inch toolpost, turret block, or quick-change holder, ensuring adequate shank engagement for rigidity. Verify insert seating and clamp torque according to the insert manufacturer guidelines before running. Do not exceed the maximum depth of cut rating for the toolholder series.
