Seco 00015848 Turning Insert DCGT32.51F-ALKX Carbide

Product Description

The SECO 00015848 is a solid carbide, uncoated turning insert with ANSI designation DCGT32.51F-ALKX and ISO code DCGT11T304F-AL. It features a 55-degree diamond (rhombic) insert shape, a positive rake geometry, and a sharp cutting edge designed for finishing and light machining operations. The inscribed circle measures 3/8 inches (0.3750 inches decimal), and the corner radius is 1/64 inch (0.0157 inches decimal). With two cutting edges and a positive side clearance, this insert is engineered for high wear resistance when cutting aluminum and non-ferrous metals. It is held by screw and suited to multi-use applications including turning, facing, boring, and back turning.

This insert is designed for machining non-ferrous metals, primarily aluminum alloys, where a sharp, uncoated carbide edge delivers superior surface finish and minimizes built-up edge. The AL chip breaker geometry supports finishing and light machining passes. It is compatible with material grades N15, N20, and N25. Typical users include CNC machinists and toolroom operators running turning centers or lathes set up for aluminum and non-ferrous workpiece materials. The neutral hand orientation gives it broad application across standard toolholder setups.

Key Features

• Solid carbide construction, bright/uncoated finish for aluminum and non-ferrous applications
• 55-degree diamond (D-shape) insert with positive rake and positive side clearance
• Sharp cutting edge with AL chip breaker optimized for finishing and light machining
• Two cutting edges per insert for extended tool life per unit
• Screw-held mounting method with neutral hand orientation
• Conforms to ANSI and ISO standards (ANSI DCGT32.51, ISO DCGT11T304)

Compatibility

Designed for use in screw-clamp turning toolholders that accept DCGT32.51 (ANSI) or DCGT11T304 (ISO) inserts. Suitable for material grades N15, N20, and N25. Compatible with back turning, boring, facing, and turning operations on non-ferrous workpiece materials. Verify toolholder pocket geometry and insert seating before use.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and de-energize the machine spindle completely before changing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer when seating the clamping screw — do not overtighten, as carbide inserts can fracture under excessive clamping force. Inspect the insert pocket and seating surface for chips or debris before installing a fresh insert.
