Hertel 7000480 Indexable Boring Bar 0.48in Min Bore Rh

Product Description

The HERTEL 7000480 is a right-hand indexable boring bar designed for precision internal boring operations on CNC lathes and machining centers. Constructed from solid carbide, this boring bar provides rigidity and vibration resistance in small-bore applications. It features a minimum bore diameter of 0.48 inches (12.19 mm), a maximum bore depth of 2.25 inches (57.15 mm), and an overall length of 6 inches. The through-coolant design channels fluid directly to the cutting zone, extending insert life and improving chip evacuation in deep-bore passes. Insert retention is achieved via a screw-holding method, allowing quick, repeatable indexing on the shop floor.

This boring bar is suited for tight-tolerance internal turning in both production and job-shop environments. The 3/8-inch shank diameter fits standard toolholding systems on smaller CNC lathes and Swiss-style machines. It is compatible with CP.. 21.51 series inserts and carries the E06SCLPR2 toolholder style designation, making it a direct specification match for shops already running that insert family. Machinists working on close-tolerance bores in steel, cast iron, and non-ferrous alloys will find this bar appropriate for finish and semi-finish boring passes.

Key Features

• Solid carbide construction for maximum rigidity in small-diameter boring applications
• Minimum bore diameter of 0.48 inches supports tight internal geometries
• Through-coolant delivery via 0.125-inch coolant hole improves chip control and tool life
• Right-hand cut orientation with screw-lock insert retention for repeatable indexing
• Maximum bore depth of 2.25 inches on a 6-inch OAL bar for reach in deeper bores
• Compatible with CP.. 21.51 inserts in the E series toolholder system

Compatibility

Designed for use with CP.. 21.51 series indexable inserts in the E06SCLPR2 toolholder style. Shank diameter is 3/8 inch, suitable for toolholding blocks and turrets sized for that bore.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and in an e-stop or lockout-tagout state. Secure the shank fully within the toolholder to the manufacturer-specified clamping depth before testing runout. Verify coolant line connections are clear and pressurized before engaging a cut. Always confirm insert seating and screw torque before the first pass.
