Kennametal 1097128 Indexable Profiling Toolholder External

Product Description

The KENNAMETAL 1097128 is an external indexable profiling toolholder designed for precision turning and profiling operations on CNC lathes and manual turning centers. Built to Top Notch series standards, this neutral-hand, neutral-rake holder uses a clamp-style insert holding method and accepts VP.. 332 series inserts with a 3/8 inch inscribed circle. The steel shank measures 1 inch by 1 inch in cross-section with a 6 inch overall length, providing a rigid platform for consistent depth-of-cut control during external profiling passes. Licensed machinists and toolroom technicians specify this holder when consistent chip clearance and repeatable insert indexing are required.

This toolholder is suited for external turning applications where a 17.5 degree lead angle geometry is needed to manage cutting forces and surface finish on shoulders, tapers, and contoured profiles. It fits standard tool post and turret positions accepting 1 inch square shank holders. The clamp-style retention keeps VP.. 332 inserts locked securely under interrupted cuts and varying feed rates. No coolant-through capability is provided, so flood or mist coolant delivery must be directed externally at the cutting zone.

Key Features

• 17.5 degree lead angle geometry for controlled cutting force direction on external profiles
• Accepts VP.. 332 series inserts with a 3/8 inch (0.375 inch) inscribed circle
• Neutral hand and neutral rake — compatible with straight or programmed profiling passes
• Clamp-style insert holding for secure retention under interrupted or heavy cuts
• Steel construction shank for rigidity and vibration damping in turning applications
• 6 inch overall length with 1 inch by 1 inch shank for standard lathe tool post fitment

Compatibility

Designed to accept VP.. 332 series inserts as specified by the KENNAMETAL Top Notch series system. Compatible insert inscribed circle is 3/8 inch (0.375 inch). Consult the KENNAMETAL Top Notch tooling catalog to confirm insert geometry and grade selection for your specific workpiece material and cutting conditions.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the toolholder from the turret or tool post. Ensure the shank seating surfaces and tool post bore are clean and free of chips before tightening. Follow the machine tool builder's torque guidelines for tool post or turret clamping hardware — do not use values from this listing as machine-specific requirements vary.
