Hertel H59875070 Boring Insert TD6P1 HT410B Solid Carbide

Product Description

The HERTEL H59875070 is a solid carbide uncoated boring insert designed for precision metal cutting operations on CNC and manual boring bars. Manufactured to the TD6P1 insert style in grade HT410B, this triangular insert features a 60-degree included angle, a 3/8-inch inscribed circle, and a 1/64-inch corner radius. The 11-degree relief angle reduces cutting forces and helps maintain tight tolerances during boring passes. At 1/8 inch thick and weighing approximately 0.03 pounds, this insert is built for rigid, screw-held toolholders used in production and job-shop environments. It is installed and replaced by machinists and CNC operators working in metalworking and machining applications.

This insert is suited for boring operations in ferrous and non-ferrous metals where an uncoated carbide grade performs reliably at moderate cutting speeds. The C2 carbide material grade makes it a practical choice for cast iron, non-ferrous alloys, and general-purpose turning or boring where coating is not required. It is a screw-held insert compatible with toolholders designed for the TD6P insert style and is sold individually with a minimum order quantity of 10 units, making it appropriate for shops that stock consumable cutting tools in quantity.

Key Features

• Solid carbide construction in material grade C2 for consistent edge strength and wear resistance
• Uncoated HT410B grade suited for general-purpose boring in cast iron and non-ferrous materials
• 60-degree triangular shape (TD6P1 insert style) with 11-degree relief angle to reduce cutting forces
• 1/64-inch corner radius (0.0150 inches decimal) for controlled surface finish in finish boring passes
• Screw-held insert mounting method for secure clamping and repeatable indexing
• 3/8-inch inscribed circle with 0.1300-inch hole diameter for standard screw-lock toolholders

Compatibility

Designed for use in screw-held boring bar toolholders that accept the TD6P1 triangular insert style with a 3/8-inch inscribed circle. Verify toolholder insert pocket specifications before ordering.

Installation Notes

Insert replacement and indexing should be performed with the machine powered down and the spindle locked. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to seat the insert properly - overtightening the clamping screw can fracture solid carbide inserts. Inspect the insert pocket seat for chips or debris before seating a new insert. Follow applicable shop safety procedures and machine tool manufacturer guidelines during all tooling changes.
