Iscar 3600015 Bbn Indexable Boring Bar 0.846 in Bore

Product Description

The ISCAR 3600015 is a BBN-style indexable boring bar engineered for internal turning operations on CNC lathes and machining centers. It accepts TP.. 32.. series triangular inserts secured by a screw-clamp holding method, providing repeatable positioning and fast insert changes at the machine. The bar features a 0.846-inch minimum bore diameter and a 3/4-inch shank diameter, with a 10-inch overall length that suits moderate reach boring applications. Rake angle is neutral (0 degrees), and the lead angle is set at 95 degrees, geometry consistent with general-purpose finish and semi-finish boring in steel, cast iron, and similar materials. The tool is part of ISCAR's Isoturn series and is compliant with ISO 13399 cutting tool data standards.

This boring bar is intended for shops and machinists performing internal diameter turning where a minimum bore of 0.846 inches is required. The 3/4-inch straight shank fits standard boring bar holders and quick-change tooling systems commonly found in production turning cells and job shop lathes. It is suited for single-point internal turning — not milling, threading, or grooving — and is classified as a single-use tool configuration. Coolant-through capability is not included, so external coolant delivery should be planned accordingly when machining heat-sensitive materials or working at higher cutting speeds.

Key Features

• Accepts TP.. 32.. series triangular inserts with compatible insert size code 32
• 0.846-inch minimum bore diameter for tight internal turning applications
• Neutral rake (0 degrees) and 95-degree lead angle for general-purpose boring geometry
• Part of the Isoturn series, compliant with ISO 13399 cutting tool data standards
• 3/4-inch shank diameter fits standard boring bar holders without adapters in most setups

Compatibility

Designed for use with TP.. 32.. series triangular indexable inserts. Insert size code is 32. Fits standard 3/4-inch boring bar holders. No specific machine model compatibility is stated by the manufacturer for this tool.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the lathe or machining center is fully powered down and the spindle is locked before mounting or changing the boring bar or its insert. Torque the insert clamping screw according to the insert manufacturer's specification printed on the insert packaging — do not estimate. Verify shank clamping length meets the toolholder manufacturer's minimum engagement requirement to prevent deflection or pullout during cutting.
