Sandvik Coromant 5782031 Laydown Threading Insert 8-16 Tpi

Product Description

The SANDVIK COROMANT 5782031 is a solid carbide laydown threading insert designed for internal right-hand 60-degree V thread cutting. It carries catalog number 266RL-16VM01A002M 1135 and belongs to the CoroThread 266 series. The insert features a TiCrAlN/TiN PVD coating for wear resistance and heat stability during threading operations. With a 3/8-inch inscribed circle and a thread range of 8-16 TPI (1.50-3.00 mm pitch), it is suited for precision internal threading on CNC lathes and turning centers. Licensed machinists and toolroom operators working in production or maintenance environments install this insert.

This insert is used in internal threading applications requiring a standard 60-degree V thread form. It is intended for use in turning centers and CNC lathes where right-hand internal threads are cut in metal workpieces. The CoroThread 266 series holder system is the intended tooling platform. Typical applications include threading bores in ferrous and non-ferrous materials across precision manufacturing, job shop, and maintenance repair operations environments. The A chipbreaker designation suits a range of threading passes on standard thread pitches within the 8-16 TPI range.

Key Features

• Solid carbide substrate provides rigidity and dimensional stability under cutting loads
• TiCrAlN/TiN PVD coating improves wear resistance and extends tool life in threading applications
• Right-hand internal thread orientation for standard bore threading operations
• 60-degree V thread standard covers UN, UNC, UNF, and metric 60-degree thread forms within the pitch range
• 8-16 TPI range (1.50-3.00 mm pitch) accommodates a broad selection of common thread sizes
• A chipbreaker geometry supports controlled chip evacuation during internal threading passes

Compatibility

Designed for use in SANDVIK COROMANT CoroThread 266 series internal threading toolholders and boring bar systems that accept the 16 insert size code. Verify holder compatibility with insert style 266 and right-hand orientation before installation.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine in a fully stopped and locked-out state per applicable machine safety procedures. Use the correct torx or hex key specified by the toolholder manufacturer to seat the insert at the proper clamping torque range indicated in the holder documentation. Do not exceed the recommended depth of cut or feed rate for the insert grade and pitch being cut. Inspect the insert seating pocket for chips or debris before securing the insert to ensure accurate thread form geometry.
