Iscar 3601970 Indexable Boring Bar 0.622 in Min Bore

Product Description

The ISCAR 3601970 is an indexable boring bar in the S-SCLCR 8-2 toolholder style, designed for internal boring and turning operations on CNC lathes and manual turning centers. Built around the Isoturn series, this right-hand holder accepts CC.T 2 diamond-shaped inserts secured by screw clamping. The bar has a 1/2-inch shank diameter and a 6-inch overall length, with a minimum bore diameter of 0.622 inches and a maximum bore depth of 1.0 inch. The negative rake geometry at -7 degrees supports stable cutting in a wide range of workpiece materials. Machinists and tool-room technicians working in production or job-shop environments are the typical end users.

This boring bar is suited for finish and semi-finish internal diameter work in both ferrous and non-ferrous materials. It is sized for smaller bore applications where controlled depth and accurate diameter are critical. The 0.350-inch center-to-cutting-edge measurement supports predictable tool positioning during setup. Typical applications include ID finishing passes on chucked parts, back-boring, and step-boring operations where a compact shank profile is required. The screw-clamp insert holding method provides repeatable insert indexing without disturbing setup.

Key Features

• S-SCLCR toolholder style accepts CC.T 2 diamond-shaped inserts
• Screw clamping for secure, repeatable insert indexing
• Minimum bore diameter of 0.622 inches for small-bore ID work
• Negative rake angle of -7 degrees for stable cutting performance
• Right-hand cut orientation for standard lathe configurations
• Conforms to ISO 13399 tooling data standards for CAM and presetter compatibility

Compatibility

Designed to accept CC.T 2 diamond-shaped indexable inserts. Insert size code 2 and the S-SCLC toolholder style are standard Isoturn series designations. Confirm insert geometry and chipbreaker selection against the workpiece material before ordering inserts.

Installation Notes

Installation and tool changes should be performed with the machine in a locked-out, de-energized state per applicable lockout/tagout procedures. Secure the 1/2-inch shank in a compatible boring bar holder or turret block and verify runout before taking a cut. Use the correct Torx or hex key for the insert clamping screw as specified in the toolholder documentation — do not overtighten. Confirm bore depth does not exceed the 1.0-inch maximum bore depth rating of this holder.
