Seco 00015861 Turning Insert TCGT32.51F-ALKX Carbide

Product Description

The SECO 00015861 is a solid carbide, uncoated turning insert designed for precision metal removal in CNC and manual turning operations. Manufactured to ANSI and ISO standards under the TCGT-AL series, this insert features a 60-degree triangular shape with a positive rake angle and a sharp cutting edge geometry. The 3/8 inch inscribed circle and 1/64 inch corner radius make it well suited for light, high-precision cuts on non-ferrous workpieces. With three usable cutting edges and screw-type holding, it delivers consistent performance in applications where surface finish and tool deflection control are priorities. Machinists and tooling specialists working with aluminum, brass, copper, and other non-ferrous materials will find this insert a direct fit for TCGT-compatible toolholders.

This insert is intended for use on non-ferrous metals, with material grades N15, N20, and N25 indicating suitability across a range of aluminum alloys and similar soft, low-abrasion materials. Multi-use application coverage includes back turning, boring, facing, and turning, making it a versatile single-pocket option on the shop floor. The AL chip breaker geometry promotes clean chip evacuation at higher surface speeds typical of aluminum machining. Shops running high-spindle-speed lathes or live-tooling setups on Swiss and CNC turning centers will find this insert a standard fit for those operations.

Key Features

• Solid carbide, bright uncoated finish optimized for non-ferrous and aluminum cutting
• 60-degree triangle insert shape with positive rake for reduced cutting forces
• Sharp cutting edge style with AL chip breaker for clean chip evacuation
• Three cutting edges per insert for extended tooling value
• Screw-type insert holding for secure, repeatable seating in standard TCGT toolholders
• Meets ANSI and ISO dimensional standards; ISO code TCGT16T304F-AL

Compatibility

Designed for use in TCGT-style screw-on toolholders compatible with TCGT32.51 insert seats. Industry standard number TCGT32.51F-AL and ISO code TCGT16T304F-AL confirm cross-reference fitment for toolholders specifying either designation. Suitable for material grades N15, N20, and N25 workpieces.

Installation Notes

Installation is performed by qualified machinists or tooling technicians using the appropriate Torx or hex key for the toolholder screw specified by the toolholder manufacturer. Ensure the toolholder pocket and seating surface are clean and free of chips before seating the insert. Do not exceed the recommended depth of cut for the insert size, and verify spindle direction and toolholder hand match the neutral insert orientation. Follow the machine tool manufacturer's lockout procedure before changing inserts.
