Seco 00015731 CCGT32.51F-ALKX Carbide Turning Insert

Product Description

The SECO 00015731 is a solid carbide, uncoated turning insert designed for precision finishing and light machining of aluminum and non-ferrous metals. It carries the ANSI insert code CCGT32.51 and ISO code CCGT09T304, with an 80-degree diamond (rhombic) shape and a positive rake geometry that promotes clean, low-force cutting. The corner radius measures 0.0157 inches (1/64 inch), and the inscribed circle diameter is 0.375 inches (3/8 inch). The KX grade designation indicates high wear resistance suited to non-ferrous workpiece materials. This insert is installed by CNC machinists and tool-and-die professionals on turning centers and boring applications.

This insert is engineered for use on non-ferrous workpiece materials, primarily aluminum, in finishing and light machining operations. Its chip breaker designation AL is optimized to produce controlled chips at higher surface speeds typical of aluminum turning. Suitable for multi-use applications including boring, facing, and turning, it fits screw-held toolholders designed for CCGT-style inserts. The positive side clearance and sharp cutting edge style reduce built-up edge on gummy non-ferrous alloys. Material grades N15, N20, and N25 indicate the applicable ISO material classification range for this insert.

Key Features

• Corner radius of 0.0157 inches for fine finishing and tight-tolerance work
• AL chip breaker geometry optimized for finishing and light machining operations
• Sharp cutting edge style reduces cutting forces and minimizes built-up edge
• Neutral hand insert with 2 usable cutting edges; screw-held mounting method

Compatibility

Designed for screw-held CCGT-style toolholders accepting a 3/8-inch inscribed circle insert. Compatible with multi-use applications including boring, facing, and turning on machines running non-ferrous workpiece materials classified under ISO material grades N15, N20, and N25. Conforms to ANSI and ISO standards as listed under ANSI code CCGT32.51 and ISO code CCGT09T304.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten, as carbide inserts are brittle and will crack under excessive clamping force. Inspect the insert pocket and seating surfaces for chips or debris before securing the insert to ensure accurate seating and consistent tool life.
