Kennametal 1021781 Lock Pin Kenloc Indexable Turning

Product Description

The KENNAMETAL 1021781 is a lock pin designed to secure indexable inserts on Kenloc-series turning toolholders. It features a 3/32 inch hex socket drive and an M6.3x1 thread, allowing a hex key to apply precise clamping torque against the insert seat. The pin is a small but critical component in the insert-retention system: when tightened, it locks the insert firmly in place during turning operations, preventing micro-movement that causes poor surface finish and premature cutting-edge failure. Machinists, tool-crib technicians, and CNC setup personnel typically handle this replacement part during routine insert changes or after pin wear or damage.

This lock pin fits Kennametal Kenloc indexable turning toolholders that use the M6.3x1 thread specification and a 3/32 inch hex socket. It is suited for production turning environments where insert changes are frequent and fast turnaround on pin replacement is necessary to keep toolholders serviceable. A single pin ships per package, with a minimum order quantity of 5 units, making it practical to stock spares at the machine or in the tool crib to avoid downtime during a changeover.

Key Features

• 3/32 inch hex socket drive for standard hex key engagement
• M6.3x1 thread size for direct fit into compatible Kenloc toolholder bodies
• Designed specifically for indexable turning insert retention
• Lightweight at 0.0157 pounds, adding negligible mass to the toolholder assembly
• Sold individually per package; order in multiples of 5 for cost-effective stocking

Compatibility

Designed for use with Kennametal Kenloc-series indexable turning toolholders requiring an M6.3x1 thread lock pin with a 3/32 inch hex socket drive.

Installation Notes

Lock pin replacement is performed by qualified machinists or toolroom technicians. Before servicing, ensure the machine spindle is fully stopped and all stored energy is released per lockout/tagout procedures. Use a calibrated 3/32 inch hex key to install and snug the pin; do not substitute an ill-fitting key, as rounding the socket will render the pin unserviceable. Inspect the mating threads in the toolholder body for damage before installing a new pin.
