Horn RS2740050011 Grooving Insert S274 TH35

Product Description

The HORN RS2740050011 is a solid carbide grooving insert in the S274 series, designed for precision grooving operations on CNC lathes and turning centers. Manufactured to the TH35 grade, this insert offers a balance of wear resistance and toughness suited for a wide range of workpiece materials. The right-hand orientation and screw-holding method provide secure, repeatable seating in compatible S274 toolholders. With a corner radius of 0.002 inches (0.05 mm) and a maximum depth of cut of 1.50 mm, this insert is built for tight-tolerance grooving work where dimensional consistency is critical.

This insert is intended for use in metal-cutting applications across a broad spectrum of materials, including cast iron, steel, stainless steel, aluminum and non-ferrous alloys, superalloys, and titanium, as reflected by its universal primary workpiece material designation. It fits into typical CNC turning and grooving setups where the S274 series toolholding system is in use. Machinists and toolroom technicians working in production or job-shop environments will find this insert appropriate for external and internal grooving tasks requiring fine corner geometry.

Key Features

• Right-hand cutting orientation for standard S274 series toolholders
• Corner radius of 0.002 inches (0.05 mm) for precise, tight-tolerance grooving
• Maximum depth of cut of 1.50 mm suits fine grooving and profiling passes
• Screw-holding method ensures secure insert clamping and repeatable indexing
• Compatible with primary workpiece material codes K, M, N, P, and S covering cast iron, steel, stainless, non-ferrous, and superalloys

Compatibility

Designed for use with S274 series toolholding systems. Compatible with primary workpiece material codes K, M, N, P, and S as specified by the manufacturer.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before indexing or replacing the insert, disengage the machine spindle and confirm the machine is in a safe, locked-out state per applicable shop safety procedures. Use the appropriate torx or hex key to seat the screw clamp to the toolholder manufacturer specification. Inspect the insert pocket for chips or debris before seating the insert to ensure proper contact and dimensional accuracy.
