Hertel 7000041 Indexable Boring Bar 0.48 in Left Hand

Product Description

The HERTEL 7000041 is a left-hand A-SCLP indexable boring bar designed for internal turning and precision bore finishing operations on metalworking lathes and boring machines. Built from steel with a 3/8-inch shank diameter and a 6-inch overall length, this tool accepts CP-style inserts secured by a screw-clamp holding method. The minimum bore diameter is 0.48 inches, making it suitable for tight-bore work where clearance is limited. A through-coolant design with a 1/16-27 NPT coolant inlet keeps the cutting zone clear and helps extend insert life during continuous cuts.

This boring bar is intended for use in production and job-shop turning environments where left-hand tool orientation is required. The A-SCLP toolholder style positions the insert with a neutral rake angle and a -5-degree lead angle, supporting controlled chip flow in a range of ferrous and non-ferrous bore finishing applications. It is sold individually and is well-suited for machinists, toolroom technicians, and CNC lathe operators working with small-diameter internal features.

Key Features

• Left-hand A-SCLP toolholder style for specific bore orientation requirements

• Neutral rake angle with -5-degree lead angle for controlled chip formation
• Steel construction with 3/8-inch shank diameter and 6-inch overall length

Compatibility

Designed to accept CP-style indexable inserts with a 1/4-inch inscribed circle and 3/32-inch insert thickness, following A-SCLP toolholder geometry standards.

Installation Notes

This tool should be installed and set up by a qualified machinist or CNC toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or changing inserts. Confirm shank clamping torque meets the machine tool manufacturer specifications for 3/8-inch boring bar holders. Verify coolant line connections are secure at the 1/16-27 NPT port before resuming coolant flow.
