Sandvik Coromant 5750145 Modular Threading Head SL32

Product Description

The SANDVIK COROMANT 5750145 is a right-hand internal modular threading cutting unit head in the CoroThread 266 series. It is designed for internal thread-turning operations on CNC lathes and turning centers where modular tooling systems are in use. The head accepts 266.R-16 inserts secured by a screw-clamping method, providing repeatable insert positioning and rigid holding. The SL32 interface size suits medium-bore threading applications, with a 32mm head length and a 22mm center-to-cutting-edge distance. A minimum hole diameter of 1.5748 inches is required for proper clearance. This unit is installed by machinists and CNC tooling specialists working in precision machining environments.

This cutting unit head is suited for internal threading on ferrous and non-ferrous workpieces in production turning setups. It is part of the CoroThread 266 modular system, which allows quick head changes without removing the shank from the machine, reducing downtime on multi-part runs. Typical applications include threading bores in hydraulic components, fittings, and precision-machined housings. The SL32 size is commonly paired with compatible CoroThread 266 shanks and adaptors within the same modular series. No specific compatible machine models were stated in the product data.

Key Features

• CoroThread 266 series modular interface for fast, repeatable head changes
• Right-hand cutting direction for standard internal threading operations
• Screw-clamp insert holding for secure, accurate insert seating
• Accepts 266.R-16 inserts
• SL32 interface size with 32mm head length and 22mm center-to-cutting-edge distance
• Minimum bore diameter requirement of 1.5748 inches for clearance

Compatibility

Designed for use with 266.R-16 threading inserts within the CoroThread 266 modular tooling system. Compatible shanks and adaptors must use the SL32 interface. No additional specific machine or shank model numbers were provided in the product data.

Installation Notes

Installation and tooling changes should be performed by a qualified machinist or CNC tooling technician with the machine powered down and the spindle locked. Use the appropriate torx or hex key as specified by the tooling system documentation when securing the insert screw. Verify that the selected shank and adaptor share the SL32 modular interface before assembly. Confirm minimum bore clearance of 1.5748 inches before committing to a toolpath.
