Kennametal 1096266 Indexable Turning Toolholder MDQNR164C

Product Description

The KENNAMETAL 1096266 is a right-hand indexable turning toolholder in the Kenloc series, designed for negative-rake external turning operations on CNC and manual lathes. It uses a clamp screw insert-holding method to secure DN-style inserts with a 0.5-inch inscribed circle. The shank measures 1 inch wide by 1 inch tall, with an overall length of 5 inches, making it a compact and rigid platform for finish and semi-finish turning. The toolholder body is constructed from steel and is intended for installation by machinists and CNC lathe operators in precision machining environments.

This toolholder is suited for external turning applications in production and job-shop settings, including general-purpose turning of ferrous and non-ferrous workpieces. The MDQN-style geometry positions the insert at a negative rake angle of -7 degrees, which is well matched to interrupted cuts and harder materials. It does not support coolant-through capability, so it is best applied in dry or flood-coolant setups where through-tool delivery is not required.

Key Features

• MDQN toolholder style with right-hand cutting orientation
• Clamp screw insert retention for secure, repeatable indexing
• Accepts DN-style inserts with 0.5-inch (1/2 inch) inscribed circle
• Negative rake angle of -7 degrees for strength and durability on harder cuts
• 1 inch x 1 inch steel shank with 5-inch overall length
• Kenloc series construction — no coolant-through, single-use application

Compatibility

Compatible with DN-style inserts carrying the complete insert compatibility designation DN.. 432. Verify insert geometry, corner radius, and chip-breaker selection against current tooling catalogs before ordering inserts.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the lathe spindle and all axes are fully powered down and locked out before mounting or removing the toolholder. Secure the shank firmly in the tool post or turret to the machine manufacturer's specified clamping requirements. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert.
