Kennametal 1095575 Threading Toolholder Left Hand 0.5in

Product Description

The KENNAMETAL 1095575 is an indexable threading toolholder in the Top Notch series, designed for both internal and external threading and grooving operations on CNC lathes and turning centers. Configured for left-hand cutting, it accepts N.3L inserts held in place by a clamp-style insert holding method. The shank measures 0.5 x 0.5 inches with a NAS-style toolholder profile, and the overall length is 6.0 inches. The maximum depth of cut is 0.21 inches. This holder is installed by machinists and CNC lathe operators in production and job-shop environments requiring precise thread-form cutting with indexable insert tooling.

This toolholder is suited for threading and grooving operations on turned components in both production and prototype settings. The left-hand orientation makes it appropriate for applications requiring cutting toward the tailstock or on reverse-rotation setups. It is a multi-use tool capable of handling both threading and grooving in a single holder platform, reducing tool change time and inventory. Shops running the Top Notch insert system can integrate this holder directly into existing tooling setups without additional adapters.

Key Features

• Supports both internal and external threading and grooving from a single holder
• Left-hand cutting orientation for reverse-rotation or tailstock-direction applications
• NAS-style shank profile for standard tool post and turret compatibility
• Clamp-style insert retention for secure, repeatable N.3L insert indexing
• 6.0-inch overall length with a 1.25-inch head length for reach and rigidity balance
• No coolant-through design — external coolant application required

Compatibility

Designed for use with N.3L indexable inserts in the KENNAMETAL Top Notch series tooling system. Fits standard NAS-style tool posts and turret stations accepting a 0.5 x 0.5 inch shank.

Installation Notes

Installation is performed by a machinist or CNC setup technician. The machine spindle must be brought to a full stop and all motion locked out before mounting or indexing tooling. Secure the shank fully in the tool post or turret station per the machine manufacturer torque guidance for that station type. Verify insert seating and clamp engagement before returning the machine to operation.
