Kennametal KTN97712M Threading Toolholder 1x1 Inch Shank

Product Description

The KENNAMETAL KTN97712M 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 with an overall length of 6 inches and accepts N.3R style inserts secured by a clamp holding method. With a maximum depth of cut of 0.210 inches and a center-to-cutting-edge distance of 0.500 inches, this holder delivers consistent positioning for threading passes. It is intended for installation and use by machinists and tooling technicians working in production or job-shop environments.

The KTN97712M is suited for threading and chamfering across a broad range of workpiece materials, including cast iron, non-ferrous metals, stainless steel, carbon and alloy steels, and heat-resistant super alloys, corresponding to material codes H, K, M, N, P, and S. The NSR163D toolholder style positions the insert for external threading operations. This holder is commonly used in horizontal and vertical turning setups where consistent insert indexing and rigid clamping are required. Each order includes 10 inserts along with the toolholder body.

Key Features

Compatibility

Designed for use with N.3R style indexable inserts in the Top Notch series. Compatible with workpiece material codes H (hardened steel), K (cast iron), M (stainless steel), N (non-ferrous), P (carbon and alloy steel), and S (heat-resistant super alloys). No specific machine model compatibility was stated in the product data.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the turret is de-energized before mounting or removing the toolholder. Secure the shank in the tool post or turret block to the required clamping torque per machine manufacturer specifications. Verify insert seating and clamp engagement before resuming cutting operations.
