Hertel 7000005 Indexable Boring Bar 0.93 in Right Hand

Product Description

The HERTEL 7000005 is a right-hand indexable boring bar designed for precision internal turning and boring operations on CNC lathes and machining centers. Built from steel with a 3/4-inch shank diameter and a 10-inch overall length, it accepts TP-style inserts held by a clamp-style insert holding method. The toolholder uses an A-CTFP style and features a positive rake geometry at 5 degrees, which reduces cutting forces and supports clean chip evacuation. Through-coolant delivery via a 1/8-27 NPT coolant hole directs fluid directly to the cutting zone, extending insert life and improving surface finish in deep bore applications.

This boring bar is suited for machining shops, tool rooms, and production environments where precise internal diameter work is required. It is used in both roughing and finishing passes on ferrous and non-ferrous materials. The 0.93-inch minimum bore diameter makes it appropriate for mid-range bore sizes where rigidity and insert stability are critical. Machinists, CNC operators, and tooling technicians install and set this bar in standard lathe or machining center turrets using standard toolholder pockets sized for a 3/4-inch shank.

Key Features

• Right-hand A-CTFP toolholder style for standard lathe and turning center use
• Through-coolant capable with 1/8-27 NPT coolant hole for directed cutting fluid delivery
• Positive rake angle of 5 degrees reduces cutting forces and supports chip control
• Clamp-style insert holding for secure, repeatable insert indexing
• 3/8-inch insert inscribed circle with 1/8-inch insert thickness for TP-style inserts
• Steel construction provides rigidity and durability in production boring applications

Compatibility

Designed for use with TP-style indexable inserts with a 3/8-inch inscribed circle and 1/8-inch thickness. Also referenced under manufacturer number A12CTFPR/L3.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before installing or indexing inserts. Secure the shank fully within the toolholder pocket to the recommended engagement depth before operation. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when connecting coolant lines to the 1/8-27 NPT port.
