Walter 6424620 Indexable Cutoff Blade Double End Neutral

Product Description

The WALTER 6424620 is a double end neutral indexable cutoff blade designed for grooving and parting operations on CNC lathes and turning centers. Built to the G2042 N blade style, it measures 32mm in height and 150mm in overall length, with a 4mm insert width and a maximum depth of cut of 50mm. The blade uses a self-grip insert holding method compatible with SX-series inserts, delivering secure insert clamping without additional fasteners. It is intended for use by machinists and tooling specialists working across a universal range of workpiece materials, including cast iron, steel, non-ferrous metals, heat-resistant alloys, and stainless steel.

This blade is suited for both production and job-shop turning environments where consistent parting and grooving performance is required across multiple material types. The neutral cutting direction makes it adaptable to standard right-hand turning setups. With a cutting height of 24.5mm and an ISO-standard profile, it fits into common toolblock systems used on medium to large turning machines. Machinists working on diameter ranges that require deep parting passes will benefit from the 50mm maximum depth of cut this blade supports.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Before changing or seating inserts, power down the machine and engage the spindle lock per the machine tool manufacturer's procedures. Ensure the blade is fully seated in the toolblock before running at any cutting speed. Verify insert engagement with the self-grip mechanism visually before initiating a cut.
