Iscar 3601071 Svjc Indexable Turning Toolholder

Product Description

The ISCAR 3601071 is a right-hand SVJC-style indexable turning toolholder from the Isoturn series, designed for external turning operations on CNC lathes and turning centers. It accepts VC..33.. style inserts secured by a screw-clamp holding method, delivering consistent insert positioning and rigid clamping under moderate to heavy cutting loads. The toolholder features a neutral rake angle of 0 degrees and a 3-degree lead angle, which helps control chip flow and cutting forces during straight turning passes. With a 1 inch by 1 inch square shank and a 6-inch overall length, it fits standard SVJC-compatible toolblocks used in production and job-shop turning environments. Installation and setup conform to ISO 13399 tooling data standards.

This toolholder is suited for turning operations in both production and job-shop environments where repeatable insert changes and tight dimensional control are required. The SVJC style is commonly used for right-hand longitudinal turning and facing applications. The compatible insert size code VCMT330-SM further narrows the fit to precision finishing and semi-finishing cuts. Licensed machinists, CNC operators, and toolroom technicians are the primary users. It is not a multi-use or coolant-through tool, making it a straightforward fixed-application holder for dry or flood-cooled setups where through-spindle coolant is not needed.

Key Features

• 6-inch overall length with 1.18-inch head length and 1.25-inch back-of-bar to cutting edge
• Steel construction and ISO 13399 compliance for integration with digital tooling libraries

Compatibility

Designed for use with VC..33.. series inserts; compatible insert size code is VCMT330-SM. Fits standard SVJC toolblocks and turret stations accepting a 1 inch by 1 inch square shank. Part of the ISCAR Isoturn series. Manufacturers catalog number SVJCR163.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before mounting or removing the toolholder. Verify shank seating depth and turret clamping torque against the machine tool builder specifications before running. Confirm insert grade and geometry selection against workpiece material and cutting parameters before the first pass.
