Hertel 1002818 Mcrn Turning Toolholder CN..432 Insert

Product Description

The HERTEL 1002818 is a right-hand MCRN-style negative rake indexable turning toolholder designed for use on CNC and manual lathes in production and job-shop turning operations. It accepts CN..432 series inserts and features a 1 inch by 1 inch square shank with an overall length of 6 inches. The negative rake geometry suits hard and interrupted cutting applications where edge strength and insert stability are priorities. Machinists and toolroom technicians working in steel, cast iron, and similar ferrous materials will find this holder fits standard tool blocks and turrets that accommodate 1 inch square shanks. The part ships as a single unit with no minimum beyond one piece.

This toolholder is intended for external turning, facing, and profiling operations on horizontal turning centers and engine lathes. The MCRN holder style positions the insert at a negative axial and radial rake angle, which provides maximum insert support during heavy roughing passes and interrupted cuts. Its right-hand designation means cutting action proceeds toward the headstock in conventional lathe orientation. The 6-inch overall length suits most standard tool post and turret setups in light industrial and production environments.

Key Features

• Right-hand cut orientation for standard lathe turning toward the headstock
• Negative rake geometry increases insert edge strength for roughing and interrupted cuts
• Accepts CN..432 indexable inserts for flexible insert sourcing
• 1 inch x 1 inch square shank fits common tool blocks and quick-change turrets
• 6 inch overall length suits standard production lathe tool stations
• HERTEL Multi-Option Series design for broad insert family compatibility

Compatibility

Designed for use with CN..432 series indexable inserts. The 1 inch x 1 inch square shank fits tool posts, quick-change tool holders, and turret stations sized for 1 inch square tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the lathe is fully powered down and the spindle is locked before seating or replacing the toolholder. Clamp the shank securely in the tool block using the manufacturer-recommended torque procedure for the block style in use. Verify insert seating and screw torque before resuming cutting operations, and confirm tool height alignment to centerline before taking the first pass.
