Seco 00034654 Turning Insert 883 Solid Carbide Mdt

Product Description

The SECO 00034654 is a solid carbide multi-directional turning insert engineered for precision external and internal turning operations. It carries the LCMR1604M0-0400-MP style designation and belongs to the MDT series. Key dimensions include a cutting width of 0.157 inches, a cutting height of 0.177 inches, and a corner radius of 0.079 inches. The insert features a full radius geometry with a neutral hand orientation and a 7-degree relief angle. The MP chipbreaker promotes controlled chip formation across a broad range of workpiece materials. Machinists and CNC lathe operators in production and job shop environments are the primary installers.

This insert is suited for turning applications on hard-to-machine materials including hardened steels, stainless steels, non-ferrous metals, and high-temperature alloys, as indicated by the primary workpiece material codes H, M, N, and S. It is designed for single-end use and arrives uncoated, making it compatible with applications where coating is unnecessary or where re-coating is performed in-house. The MDT series is commonly applied in grooving and turning operations that require consistent dimensional control and smooth surface finish.

Key Features

• Solid carbide construction with Material Grade C2 for wear resistance in demanding cuts
• Full radius insert geometry for smooth profiling and contour turning
• MP chipbreaker design supports chip control across multiple material categories
• Neutral hand orientation allows flexible toolholder pairing
• Uncoated finish suits applications requiring tight dimensional tolerances without coating buildup
• Single-end configuration ensures consistent edge presentation at the cutting zone

Compatibility

Designed as an OEM-style replacement or direct-fit insert for LCMR-style toolholders within the MDT series accepting the LCMR1604M0 insert size code.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to achieve proper clamping force without cracking the carbide substrate. Inspect the insert seat and clamping screw for debris or damage before each installation.
