Hertel 7000006 Indexable Boring Bar 1.2in Left Hand

Product Description

The HERTEL 7000006 is a left-hand indexable boring bar designed for precision internal turning and boring operations on CNC lathes and machining centers. Built with a steel shank, it accepts A-CTFP style inserts with a TP.. insert compatibility designation, a 3/8-inch inscribed circle, and 1/8-inch insert thickness. The bar features through-coolant capability via a 1/4-18 NPT coolant hole, directing fluid directly to the cutting zone to manage heat and chip evacuation. With a positive rake design and a 5-degree rake angle, it supports efficient cutting action on a wide range of workpiece materials. This tool is handled and installed by machinists and toolroom technicians in production and job-shop environments.

The 7000006 boring bar is suited for internal diameter operations requiring a minimum bore of 1.2 inches. The 1-inch shank diameter and 12-inch overall length make it appropriate for medium-reach boring applications on horizontal and vertical turning centers. The 0-degree lead angle provides a straightforward cutting geometry for standard internal facing and finishing passes. The clamp-style insert holding method provides rigid tool retention during interrupted cuts and continuous roughing passes.

Key Features

• Left-hand holder orientation for specific turret and spindle configurations
• Through-coolant ready with 1/4-18 NPT coolant port for directed flood or high-pressure coolant delivery
• Positive rake geometry at 5 degrees supports reduced cutting forces and cleaner chip formation
• Clamp-style insert retention provides rigid holding for heavy and interrupted cuts
• Steel shank construction for durability in standard boring applications
• 0-degree lead angle for direct radial cutting engagement

Compatibility

Designed for use with A-CTFP style indexable inserts with a TP.. designation, 3/8-inch inscribed circle, and 1/8-inch thickness. Compatible with toolholding systems accepting a 1-inch round shank.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and all stored energy released before tool changes. The shank should be clamped securely in the boring bar holder to the manufacturer-recommended engagement depth to prevent deflection during cutting. Verify coolant line connection to the 1/4-18 NPT port is leak-free before initiating a cycle. Confirm insert seating and clamp torque according to the insert manufacturer specifications before running at full depth of cut.
