Sandvik Coromant 5750159 Threading Cutting Unit Head SL40

Product Description

The SANDVIK COROMANT 5750159 is a right-hand internal modular threading cutting unit head from the CoroThread 266 series. Designed for internal threading operations, this cutting unit head features an SL40 interface size with a 32mm head length and a 26.9mm center-to-cutting-edge distance. It uses a screw-based insert holding method and accepts 266.R-22 inserts. With a minimum hole diameter of 1.9685 inches, it is suited for precision threading in medium to larger bore applications. This tool is installed by machinists and CNC tooling specialists working on turning centers or boring applications requiring repeatable, accurate thread profiles.

The 5750159 is used in internal threading applications on CNC lathes and turning centers where modular tooling systems are employed. The SL40 modular connection provides a secure, repeatable interface for consistent performance across production runs. The right-hand cutting direction makes it compatible with standard forward-feed threading cycles. It is a fit for shops running precision threading on components requiring controlled thread geometry in medium to large diameter bores.

Compatibility

Designed for use with 266.R-22 inserts as part of the CoroThread 266 modular threading system. Compatible with SL40 modular tooling interfaces on CNC turning centers and lathes configured for internal threading operations.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician familiar with modular turning tool systems. Ensure the machine spindle and turret are fully stopped and locked out before mounting or changing the cutting unit head. Follow the tool manufacturer torque guidelines for the SL40 interface clamping screws as specified in the tooling system documentation. Confirm insert seating and screw torque before resuming cutting operations.
