Hertel 8850563 Ceramic Turning Insert TNG432T00825 HT601CA

Product Description

The HERTEL 8850563 is a ceramic uncoated turning insert in the TNG style, designed for metal cutting and turning operations on CNC lathes and manual turning machines. Manufactured to grade HT601CA, this insert features a 60-degree triangular shape with a neutral hand orientation and a negative rake geometry. The inscribed circle measures 0.5 inches, the insert length is 0.866 inches, and the corner radius is 0.0312 inches (1/32 inch). It is clamp-held and suited for hard-turning and high-speed finishing applications where ceramic tooling outperforms carbide in thermal resistance. Licensed machinists and CNC operators working in production turning environments are the primary installers.

This turning insert is used in external turning operations on ferrous and hardened materials in both production shop and job-shop environments. The TNG style with clearance code N and tolerance code G makes it a standard drop-in for toolholders designed around the TNG insert family. Applications include finish turning and semi-finish turning where ceramic grades deliver consistent tool life at elevated cutting speeds. No chip breaker geometry is present, making this insert appropriate for continuous cuts requiring a clean, flat rake face.

Key Features

• Ceramic uncoated insert material for high-speed, high-temperature turning applications
• 60-degree triangular insert shape with insert size code 432 provides multiple cutting edges per insert
• Neutral hand orientation fits standard TNG-style toolholders without left or right hand restriction
• Negative rake geometry increases edge strength and supports interrupted and continuous cut stability
• Corner radius of 0.0312 inches (1/32 inch) balances surface finish quality with edge durability
• No chip breaker for unobstructed chip flow on continuous turning passes

Compatibility

Designed for use in TNG-style clamp-held toolholders accepting a 0.5 inch inscribed circle triangular insert with clearance code N and tolerance code G. Compatible insert style is TNG432-T00825 as designated by the manufacturer.

Installation Notes

Installation should be performed by qualified machinists following the toolholder manufacturer's clamping torque and seating procedures. Always power down and lock out the machine before changing inserts. Inspect the toolholder pocket and clamp for wear or debris before seating the insert. Ceramic inserts are brittle and should not be used for interrupted cuts or operations subject to heavy vibration unless the grade is rated for such conditions by the manufacturer.
