Seco 00045736 Laydown Threading Insert CP500 Solid Carbide

Product Description

The SECO 00045736 is a solid carbide laydown threading insert designed for internal threading operations. It carries the CP500 grade with a TiAlN/TiN PVD coating applied through a physical vapor deposition process, delivering wear resistance across a broad range of workpiece materials. The insert features a left-hand, partial-profile 60-degree included angle geometry suited for cutting internal threads from 48 to 16 TPI, covering metric pitches of 0.50 to 1.50 mm. The inscribed circle measures 0.2500 inches and the insert thickness is 0.1181 inches. Licensed machinists and CNC toolroom technicians install this insert into compatible Snap Tap series toolholders.

This insert is intended for internal threading on a wide variety of workpiece materials, classified under universal material grades including ISO material groups K, M, P, and S. That coverage makes it applicable across cast iron, steel, stainless steel, and superalloy turning and boring operations in both production and job-shop environments. The left-hand orientation accommodates specific spindle direction or part geometry requirements. It is sold individually with a minimum order quantity of two units.

• Left-hand internal partial profile geometry for 60-degree thread form
• Covers 48 to 16 TPI range and 0.50 to 1.50 mm pitch range in a single insert
• ISO-standard geometry compatible with Snap Tap series holders
• Corner radius of 0.0030 inches for controlled thread root profile

Compatibility

Designed for use in SECO Snap Tap series toolholders accepting the 11NL insert style. Compatible with ISO-standard holders matching the 11NL insert size code. Verify holder pocket specifications before installation.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque wrench and insert screw driver as specified by the toolholder manufacturer to avoid over-torquing the clamp screw. Inspect the toolholder pocket for chips or damage before inserting a new tip, as debris under the insert seat will affect thread accuracy.
