Kennametal 1096271 Indexable Turning Toolholder MDQNL124B

Product Description

The KENNAMETAL 1096271 is a left-hand indexable turning toolholder in the MDQNL style, designed for use on CNC and manual lathes in metal-cutting operations. It features a 3/4 x 3/4 inch square shank with an overall length of 4.5 inches and accepts DN-style negative-rake inserts held in place by a clamp and screw method. The Kenloc clamping system provides rigid insert retention and repeatable edge positioning, making this toolholder a dependable choice for external turning applications. Steel construction ensures durability under continuous cutting loads. No coolant-through capability is present on this model.

This toolholder is suited for external turning on production and job-shop lathes where left-hand cutting direction is required. The MDQNL style positions DN-style inserts at a negative rake angle of -7 degrees, making it appropriate for general-purpose turning of steel, cast iron, and similar machinable materials. It is compatible with DN.. 432 series inserts with a 1/2-inch inscribed circle. Machine operators, CNC programmers, and toolroom machinists working in manufacturing environments are the primary users of this toolholder.

Clamp the shank securely in the tool post or turret to the full recommended grip length to prevent deflection under cutting loads. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool height and registering cutting edge position.
