Horn RS27405100310TH35 Grooving Insert S274 TH35

Product Description

The HORN RS27405100310TH35 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Built to S274 series geometry with a TH35 manufacturer grade, this insert delivers consistent edge performance across a broad range of workpiece materials. The right-hand cutting orientation and screw-clamping holding method ensure secure, repeatable seating in compatible S274 toolholders. A corner radius of 0.0200 inches (0.50 mm) suits fine grooving and profiling work where controlled chip formation and edge geometry are critical to part quality.

This insert is suited for production turning environments where machinists and CNC operators require reliable grooving performance across universal workpiece material classifications. The TH35 carbide grade is rated for use on cast iron, non-ferrous materials, non-metallic materials, steel, and heat-resistant superalloys, covering primary workpiece material codes K, M, N, P, and S. It is appropriate for both job shop and high-volume production settings where consistent depth-of-cut control is required up to a maximum of 3.00 mm.

Key Features

• Solid carbide construction with TH35 manufacturer grade for broad material compatibility
• S274 series insert geometry optimized for grooving and profiling operations
• Right-hand cutting orientation for standard lathe grooving setups
• Screw holding method provides secure insert clamping and precise repeatability
• Corner radius of 0.0200 inches (0.50 mm) for fine groove profiling
• Maximum depth of cut of 3.00 mm supports a range of groove width applications

Compatibility

Designed for use with S274 series compatible toolholders and grooving systems. Primary workpiece material codes K, M, N, P, and S are supported, covering cast iron, non-ferrous, non-metallic, steel, and heat-resistant superalloy workpieces.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key driver to seat the clamping screw to the toolholder manufacturer specification. Inspect the insert pocket and seating surface for chips or contamination before seating the insert to ensure accurate positioning and safe operation.
