Widia 6788453 Indexable Grooving Blade 35.5 Mm Neutral

Product Description

The WIDIA 6788453 is a modular indexable grooving blade designed for grooving and cut-off operations on CNC lathes and turning centers. Built from steel with a wedge-style insert holding method, this single-end blade stands 35.5 mm tall and accepts a 3.00 mm wide insert. It is compatible with WC, WG, and WR style inserts in size code 3, making it a versatile tooling component for shops running tight-tolerance grooving work. The neutral cutting direction suits straight radial grooving applications. Machinists and tooling specialists in production and job shop environments rely on blades like this for consistent, repeatable groove geometry.

This blade belongs to the WGCMSU-B series and is suited for grooving and cut-off applications on workpieces with a minimum and maximum workpiece diameter of 3.0 inches. The maximum depth of cut is 1.5 inches, making it appropriate for moderate-depth grooving on steel, stainless, and similar materials. It is commonly installed in modular blade holder systems on CNC turning equipment in both production machining and precision job shop environments.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CNC turning center setup. The machine spindle must be stopped and the turret fully indexed to a safe position before blade changeout. Confirm insert style and size code compatibility before seating any insert, and verify clamping torque per the toolholder manufacturer guidelines. Follow all applicable shop safety procedures when handling sharp cutting tool components.
