Iscar 3601217 Indexable Boring Bar Right Hand Through Coolant

Product Description

The ISCAR 3601217 is a right-hand indexable boring bar designed for internal turning operations on CNC lathes and machining centers. Part of the Isoturn series, it accepts VN.. 2.5 diamond-shaped inserts held by a screw-clamp method, providing secure seating under interrupted and continuous cuts. The bar features a 3/4-inch shank diameter and 7-inch overall length, with a minimum bore diameter of 1.04 inches and a maximum bore depth of 1.2 inches. A negative axial and negative radial rake geometry, combined with a -7-degree lead angle, suits a wide range of ferrous and non-ferrous turning materials. Through-coolant capability delivers cutting fluid directly to the insert tip, extending tool life and improving chip evacuation in deep bores.

This boring bar is suited for production turning environments where consistent bore geometry and insert repeatability are required. The A-SVUNR 12-2.5 toolholder style targets shops running internal diameter finishing and semi-finishing passes on components with bores starting at 1.04 inches. Machinists and CNC programmers in job shops, production facilities, and aerospace or automotive machining cells will find this bar appropriate for right-hand cutting setups where through-coolant capability is an asset.

Key Features

• Through-coolant design delivers coolant directly to the cutting zone for improved chip control and insert life
• Accepts VN.. 2.5 diamond-shaped inserts with screw-clamp holding method for rigid, repeatable positioning
• Negative axial and negative radial rake geometry suitable for a broad range of workpiece materials
• -7-degree lead angle in A-SVUNR 12-2.5 toolholder style for controlled entry and reduced radial forces
• 3/4-inch shank diameter with 7-inch OAL fits standard lathe and machining center tooling blocks
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems

Compatibility

Designed for use with VN.. 2.5 compatible diamond-shaped inserts. Toolholder style is A-SVUNR 12-2.5 per ISO 13399. Verify insert size code 2.5 and VN.. seating geometry when selecting replacement inserts.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or removing the boring bar from the toolholder block. Verify through-coolant port alignment with the machine turret or tool block coolant supply before tightening. Follow the machine tool manufacturer torque guidelines for the toolholder clamping screws and confirm insert seating before taking a cut.
