Kennametal KTN96677E Threading Toolholder 1x1 in Shank

Product Description

The KENNAMETAL KTN96677E is a right-hand indexable threading toolholder from the Top Notch series, designed for precision threading and chamfering operations on CNC lathes and turning centers. The toolholder features a 1 x 1 inch square shank and accepts N.3R insert geometry, held in place by a clamp-style insert holding method. At 6 inches overall length with a 1.25-inch head length, this toolholder provides rigid support during cut. Weighing 0.392 pounds, it is suitable for a broad range of workpiece materials including hardened steels, cast iron, stainless, non-ferrous, carbon steels, and high-temperature alloys. This is a multi-use tool and ships with 10 inserts included.

The KTN96677E is intended for threading and chamfering applications in production and job-shop turning environments. The NSR163D toolholder style fits standard lathe tool blocks and turret stations that accept 1-inch square-shank tooling. Compatible workpiece material codes cover H, K, M, N, P, and S classifications, making it broadly applicable across ferrous, non-ferrous, and exotic alloy turning work. The maximum depth of cut is 0.21 inches, with a center-to-cutting-edge distance of 0.50 inches and a back-of-bar to cutting edge dimension of 1.25 inches. No coolant-through capability is included; coolant entry style is coded as without coolant.

Installation Notes

Installation of indexable turning toolholders should be performed by a qualified machinist or CNC setup technician with the machine powered down and the spindle fully locked. Confirm the turret or tool block bore is clean and free of debris before seating the shank. Torque clamp screws per the machine tool manufacturer's specifications — do not use impact tools on insert clamp hardware. Verify tool offset and cutting edge height at centerline before initiating a test pass.
