Seco 00013014 Mcln Rh Indexable Turning Toolholder

Product Description

The SECO 00013014 is an MCLN-style right-hand indexable turning toolholder designed for external turning operations on CNC and manual lathes. Built on the Multiple Lock series, it uses a clamp-and-pin insert holding method to secure negative-rake CN..64 inserts — specifically CNMG 643 geometry — with consistent repeatability. The shank measures 1.5 inches wide by 1.5 inches tall, with an overall length of 7 inches and a head length of 1.49 inches. A -6-degree rake angle and -5-degree lead angle position the insert for stable, controlled cuts across a broad range of workpiece materials. Licensed machinists and CNC programmers install this toolholder in production and job-shop turning applications.

This toolholder is rated for universal workpiece material compatibility, covering material codes H, K, M, N, P, and S — spanning steels, stainless alloys, cast irons, non-ferrous metals, high-temperature alloys, and more. The right-hand cutting direction makes it suited for standard OD turning toward the chuck. The back-of-bar to cutting-edge dimension is 2 inches, which factors into tool offset setup during presetting. No coolant-through capability is present, so external flood or mist coolant delivery applies where needed.

Key Features

• MCLN toolholder style with Multiple Lock (clamp and pin) insert retention for rigidity and repeatability
• Accepts CN..64 inserts; complete compatibility with CNMG 643 insert geometry
• Negative rake angle of -6 degrees for stable cutting on harder and interrupted materials
• 1.5 inches x 1.5 inches square shank fits standard OD turning tool blocks and turrets
• Universal material code coverage: H, K, M, N, P, S workpiece materials
• Right-hand cutting direction, 7-inch overall length for standard reach applications

Compatibility

Designed to accept CN..64 series inserts, with complete compatibility confirmed for CNMG 643 inserts. Fits standard square-shank turning tool stations with a 1.5-inch by 1.5-inch bore or pocket.

Installation Notes

Installation and tool changes should be performed by qualified machinists or toolroom personnel with the machine in a full stop and energy-isolated state per OSHA lockout-tagout procedures. Confirm insert seating and clamp screw torque per the toolholder manufacturer's specification before resuming cuts. Verify tool offset and back-of-bar-to-cutting-edge dimension on the machine preset station before engaging the workpiece. Do not exceed the insert or toolholder's rated depth of cut or feed rate for the workpiece material being machined.
