Iscar 3601349 Indexable Boring Bar S-mwln Right Hand

Product Description

The ISCAR 3601349 is a right-hand indexable boring bar designed for internal turning operations on CNC and manual lathes. Part of the Isoturn series, this S-MWLN-style toolholder accepts trigon-shaped WNM.. 43.. inserts secured by a wedge-clamping method. The bar has a 14-inch overall length and a 1-1/2-inch shank diameter, giving it the rigidity needed for deeper bores. A negative rake angle of -10 degrees and a center-to-cutting-edge distance of 0.89 inches are built into the geometry, optimizing chip control on ferrous and non-ferrous workpiece materials. The steel construction keeps the shank stable under interrupted cuts and typical shop turning loads.

This boring bar is suited for right-hand internal turning applications where a minimum bore diameter of 1.76 inches and a maximum bore depth of 2.16 inches fall within the required range. It is appropriate for production turning shops, job shops, and maintenance machining environments. The toolholder complies with ISO 13399 standards, making it compatible with digital tool-data workflows. It is installed by machinists and toolroom technicians working on lathe turrets or boring heads that accept a 1-1/2-inch round shank.

Key Features

Compatibility

Designed to accept WNM.. 43.. series trigon inserts with a compatible insert size code of 43. Confirm insert geometry and tolerance class with ISCAR insert selection guides before ordering inserts separately.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the lathe spindle before mounting or removing the boring bar from the turret. Ensure the shank bore in the toolholder block is clean and free of chips before seating the 1-1/2-inch shank. Torque the clamping screws to the machine or turret manufacturer specifications — do not use values from this listing, as none are provided by the manufacturer for this item.
