Sandvik Coromant 5753754 Threading Insert Carbide Tialn

Product Description

The SANDVIK COROMANT 5753754 is a carbide threading insert designed for both internal and external thread cutting across a pitch range of 1.25 to 5.00 mm (5 to 20 TPI). It carries a TiAlN finish applied via PVD coating process, which improves heat resistance and tool life in demanding threading operations. The insert features a 60-degree V thread form and is classified as a right-hand, Size 3 insert within the Top Lok series. Machinists and CNC operators working in production or job-shop environments install this insert into compatible Top Lok toolholders for threading ferrous and non-ferrous workpiece materials.

This insert is suited for threading applications on CNC lathes and turning centers where consistent thread form and repeatable positioning are required. Its dual-duty internal and external thread capability makes it a practical option for shops running varied threading work without switching insert grades. The 60-degree included angle covers the most common unified and metric thread standards encountered in general machining. The TiAlN PVD coating supports higher cutting speeds and extended tool life compared to uncoated carbide inserts.

Key Features

• Carbide substrate with TiAlN PVD coating for improved wear resistance and heat tolerance
• Cuts both internal and external threads with a single insert grade
• 60-degree V thread form covering metric pitches 1.25 to 5.00 mm and imperial 5 to 20 TPI
• Right-hand cutting geometry, Size 3, Top Lok series for secure, repeatable seating
• Corner radius of 0.17 mm (0.0065 inches) for controlled thread root form
• ISO code TLTP-3R 1125 for direct cross-reference and toolholder matching

Compatibility

Designed for use with Top Lok series threading toolholders that accept a Size 3 TLTP-style insert. Confirm toolholder compatibility using ISO code TLTP-3R before installation.

Installation Notes

Insert installation should be performed by a qualified machinist with the machine powered down and the spindle locked or in a safe state. Use the appropriate torx or clamping key specified for the Top Lok toolholder to seat the insert; do not over-torque the clamping screw. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and thread accuracy. Follow the toolholder manufacturer's setup instructions for insert orientation and clamping torque.
