Seco 00041947 Differential Screw Torx Plus Indexables

Product Description

The SECO 00041947 is a differential screw designed for indexable turning toolholders and clamping systems. Differential screws use a dual-thread design to produce fine clamping movement, holding inserts and clamps securely during interrupted cuts and high-feed turning operations. This screw features a Torx Plus drive, which provides greater torque transfer and reduced risk of cam-out compared to standard hex drives. It is used by machinists and toolroom technicians working with SECO-compatible indexable turning setups requiring precise, repeatable insert clamping. At 0.02 pounds, it is a lightweight but critical hardware component in maintaining insert position and tool integrity.

This differential screw is intended for indexable turning applications. It is compatible with cartridge, clamp, insert, and toolholder assemblies. Clamp compatibility includes CLM-12, CLM-17, CLM-27, CLM-5, and CLM-6. Supported insert inscribed circle sizes range from 0.25 inches to 0.50 inches. This part is sold individually and is appropriate for benchtop toolroom use, CNC lathe setup, and field replacement of worn or damaged clamping hardware.

Compatibility

Compatible with CLM-12, CLM-17, CLM-27, CLM-5, and CLM-6 clamp systems. Supports cartridge, clamp, insert, and toolholder hardware in indexable turning configurations with insert inscribed circle sizes of 0.25, 0.375, and 0.50 inches.

Installation Notes

Installation is performed by machinists or toolroom technicians during insert changes or clamp servicing on indexable turning tools. Ensure the toolholder is clear of the machine spindle and all power is off before replacing clamping hardware. Use a calibrated Torx Plus driver of the appropriate size to avoid stripping the drive recess. Do not reuse visibly damaged or deformed differential screws, as compromised threads can cause insert movement during cutting.
