Hertel 7000442 Indexable Boring Bar 1 in Shank A16SCLPR3

Product Description

The HERTEL 7000442 is a steel indexable boring bar designed for internal turning and boring operations on CNC lathes and turning centers. Built to the A16SCLPR3 toolholder style, it features a 1 inch shank diameter and a 12 inch overall length, making it suited for reaching into deep bores with consistent rigidity. The minimum bore diameter is 1.2 inches (30.48 mm), and the maximum bore depth is 3 inches (76.20 mm). The insert is secured by screw clamp, and the bar is compatible with CP.. 32.52 series inserts. Coolant-through capability is built in, with a 1/4-27 NPT coolant hole for directed high-pressure coolant delivery to the cutting zone.

This boring bar is intended for right-hand cut operations and is a standard choice for machinists and toolroom operators performing finish or semi-finish boring on steel, cast iron, and similar workpiece materials. The A16SCLPR3 designation identifies the shank size, insert style, and cutting geometry, making cross-referencing to insert catalogs straightforward. It fits conventional CNC lathe turrets that accept 1 inch round shank tooling and is well-suited to production environments where repeatability and fast insert indexing are priorities.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the control is in a safe state before changing or indexing inserts. Torque the clamp screw to the insert manufacturer specification using the appropriate Torx or hex key. Verify shank seating depth and overhang against the maximum bore depth rating before commencing a cut to prevent tool deflection or chatter.
