Kennametal 1096039 Mssn Indexable Turning Toolholder

Product Description

The KENNAMETAL 1096039 is a right-hand MSSN-style indexable turning toolholder built for negative-rake external turning operations on CNC lathes and manual turning centers. It features a 3/4 inch by 3/4 inch steel shank with an overall length of 4.5 inches, and it accepts SN..43. series inserts secured by a clamp-and-screw insert holding method. Part of the Kennametal Kenloc series, this toolholder is designed for rigid, repeatable insert positioning in high-production turning environments. It weighs approximately 0.78 pounds and is manufactured from steel for durability under interrupted and continuous cutting conditions.

This toolholder is suited for external turning applications in both production and job-shop environments. The 45-degree lead angle geometry distributes cutting forces effectively, making it appropriate for general-purpose turning of ferrous and non-ferrous materials. The right-hand cutting orientation positions the tool for conventional front-facing lathe operations. Licensed machinists and CNC operators working in metalworking, aerospace, automotive, and general manufacturing will find this holder fits standard gang-tooling and turret setups requiring a 3/4 inch square shank.

Key Features

• Right-hand MSSN toolholder style with 45-degree lead angle for balanced radial and axial force distribution
• Accepts SN..43. series inserts (complete compatibility: SN.. 432) using clamp-and-screw retention
• 3/4 inch x 3/4 inch shank — 0.7500 inch width by 0.7500 inch height (19.05 mm)
• 4.5 inch overall length with 1.24 inch head length and 0.662 inch back-of-bar to cutting edge dimension
• Negative rake geometry for increased insert edge strength and longer tool life in heavy-cut applications
• Kenloc series steel construction — no coolant-through provision

Compatibility

Designed to accept SN..43. series indexable inserts; complete insert compatibility is SN.. 432. Manufacturer catalog number MSSNR124B. Verify insert nose radius and chipbreaker designations against the Kennametal Kenloc toolholder system specifications before ordering inserts.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the toolholder in the turret or tool post with the shank fully engaged to the minimum clamping depth recommended by the machine tool manufacturer. Power down and lock out the machine before changing inserts or repositioning the holder. Do not exceed the machine spindle speed or depth-of-cut limits specified for this shank size and insert geometry.
