Hertel 1000168 Mtgn Indexable Turning Toolholder

Product Description

The HERTEL 1000168 is a right-hand MTGN-style indexable turning toolholder designed for external turning operations on CNC and manual lathes. It features a negative rake geometry at -5 degrees, which promotes strong cutting edge support and longer insert life when machining tough materials. The 3/4 inch by 3/4 inch square steel shank provides a rigid, stable platform for consistent tool positioning. The toolholder accepts TN..43. series inserts and is engineered for machinists and toolroom professionals who require reliable, repeatable performance in production turning environments.

This toolholder is suited for use in standard turning center and engine lathe setups where a right-hand cutting direction is required. The 3-degree lead angle and 4.5-inch overall length make it compatible with common tool post and turret configurations. It is appropriate for both light-duty production runs and general-purpose external turning on a range of workpiece materials. The insert seat accommodates inserts with a 0.5 inch inscribed circle diameter, keeping insert selection straightforward for shops already stocked with TN..43. geometry tooling.

Key Features

• Negative rake angle of -5 degrees for strong cutting edge support and improved tool life
• Right-hand holder orientation for standard external turning setups
• 3/4 inch by 3/4 inch square shank for rigid clamping in tool posts and turrets

Compatibility

Designed to accept TN..43. series inserts, specifically compatible with TN.. 432 insert geometry. Verify turret or tool post bore dimensions against the 3/4 inch shank size before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the lathe or turning center is powered down and in a safe lockout/tagout state before mounting or removing the toolholder. Seat the shank fully in the tool post or turret block and torque all clamping screws evenly to manufacturer specifications using appropriate hex keys. Confirm insert is properly seated and clamped before resuming cutting operations.
