Iscar 3690703 Indexable Boring Bar 25mm Right Hand

Product Description

The ISCAR 3690703 is a right-hand S-SVJC indexable boring bar engineered for internal turning operations on CNC lathes and turning centers. Built from steel with a 20mm shank diameter and a 200mm overall length, this toolholder accepts VC.T 1103.. inserts secured by a screw clamping method. The negative rake angle of -3 degrees and diamond insert shape make it well suited for finishing and semi-finishing passes in bores starting at 25mm. Installation requires no coolant-through capability. Part of the ISCAR Isoturn series, it conforms to ISO 13399 tooling data standards for seamless integration with CAM and tooling management systems.

This boring bar is intended for internal diameter turning in a shop or production environment where consistent bore geometry and repeatable insert indexing are required. It handles a maximum bore depth of 37mm, making it appropriate for shallow-to-mid-depth bore profiles in steel and similar materials. The toolholder is designed for use by machinists and CNC setup technicians running production or job-shop turning work.

Installation Notes

This toolholder is installed and set up by qualified machinists or CNC toolroom technicians. Power down and lock out the machine before inserting or indexing cutting inserts. Verify shank clamping torque per your machine tool manufacturer specifications before running. Confirm bore clearance against the 25mm minimum bore diameter before use to avoid tool or workpiece damage.
