Seco 00005686 Pcd Turning Insert 3/8 Inch Ic Ccmw

Product Description

The SECO 00005686 is a single-tipped polycrystalline diamond (PCD) turning insert designed for high-speed machining of non-ferrous metals and other difficult-to-cut materials. Built to the CCMW series flat-top geometry, it features an 80-degree diamond insert shape with a positive rake angle and sharp cutting edge for clean, efficient material removal. The insert carries a 3/8 inch inscribed circle, a 1/64 inch corner radius (0.0157 inches decimal), and an insert thickness of 5/32 inch (0.1563 inches). It is uncoated bright PCD, making it well suited for applications where a coated carbide insert would wear prematurely. Machinists and CNC tooling technicians install this insert using a screw-holding method on compatible toolholders.

This insert is intended for turning, facing, and boring operations on non-ferrous metals including aluminum alloys, copper, and similar materials in both production and job-shop environments. The flat-top chip breaker geometry and sharp edge minimize built-up edge on gummy materials. It conforms to both ANSI and ISO standards, with an ISO code of CCMW09T304F-L1 and an industry standard number of CCMW32.51F-L1, allowing direct cross-reference to compatible toolholders. Material grade designations N10, N15, and N20 indicate suitability across a range of non-ferrous workpiece hardness levels.

Key Features

• Polycrystalline diamond (PCD20 grade) cutting material — uncoated bright finish
• 80-degree diamond insert shape (CCMW series, flat-top chip breaker)
• 3/8 inch inscribed circle (0.3748 inches decimal) with 1/64 inch corner radius
• Positive rake, sharp cutting edge style for reduced cutting forces on non-ferrous materials
• Single cutting edge; screw-held; neutral hand orientation
• Rated for turning, facing, and boring operations; maximum depth of cut 0.0669 inches

Compatibility

Designed as an OEM-style replacement or direct-fit insert for CCMW-series screw-clamp toolholders conforming to ANSI and ISO standards. Cross-references to ISO designation CCMW09T304F-L1 and industry standard number CCMW32.51F-L1 for toolholder matching. Intended for use with non-ferrous workpiece materials in material grade classifications N10, N15, and N20.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle before seating or removing the insert. Secure the insert using the manufacturer-specified clamping screw for the toolholder; do not over-torque or substitute fasteners. Inspect the pocket seating surface for chips or debris before installing a new insert, as poor seating will accelerate edge wear and reduce dimensional accuracy.
