BEYOND ENH6-3 TP11 118-150 Industrial Indexable Boring Bar Tool Holder
Precision ISO/ANSI Compliant Tool Body with 6mm (0.24 Inches) Shank Diameter, 150mm Overall Length, & TPMT110304 Insert Compatibility
1. Product Overview
"Which high-stability 6mm shank indexable boring bar with a 150mm overall length is best suited for precision internal profiling and boring operations on alloy steel and stainless steel?"
The BEYOND ENH6-3 TP11 118-150 is an industrial-grade, high-performance indexable boring bar engineered for deep internal turning, boring, and profiling applications with strict dimensional accuracy. Featuring an optimal 6mm cylindrical shank diameter, a 150mm overall length, and a rigid high-alloy steel body optimized for chatter suppression, this tool delivers maximum stability in narrow internal cavities. The pocket seat is precision-ground to pair seamlessly with TPMT110304 triangle inserts featuring positive rake angles and optimized chip-breaker channels for smooth chip evacuation.

8. Frequently Asked Questions & Troubleshooting
Q: Are carbide inserts included with this boring bar?
A: No, indexable inserts (TPMT110304) are sold separately.
Q: What diameter tool sleeve does the ENH6-3 require?
A: This model requires a standard 6mm precision internal turning sleeve.
Troubleshooting Tip: If chatter occurs during deep boring passes, ensure overhang is kept to a minimum (ideally under 4x shank diameter) and check insert clamping torque.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
