Iscar 3601191 Indexable Boring Bar 25mm Left Hand A-pwln

Product Description

The ISCAR 3601191 is a left-hand indexable boring bar designed for internal turning operations on CNC lathes and turning centers. Built to the A-PWLN toolholder style within ISCAR's Isoturn series, it accepts WNM 06T3 trigon inserts held by a lever clamping mechanism. The bar features a 20mm shank diameter and a 180mm overall length, providing the rigidity needed to reach a maximum bore depth of 36mm. A through-coolant channel delivers cutting fluid directly to the insert tip, improving chip evacuation and extending tool life in demanding bore finishing and roughing applications. Machining professionals and CNC setup technicians are the primary users.

This boring bar is suited for left-hand internal turning where the spindle rotation and tool orientation require a left-cutting-direction setup. It opens bores to a minimum diameter of 25mm, making it appropriate for mid-range bore diameters common in production turning of steel and similar materials. The negative rake geometry at -14 degrees and trigon insert shape support aggressive material removal while maintaining a secure insert seating. Applications span job shops, production machining facilities, and tool rooms requiring consistent bore geometry.

Key Features

• A-PWLN toolholder style from the Isoturn series for consistent insert positioning
• Accepts WNM 06T3 trigon inserts with lever clamping for secure, repeatable seating
• Through-coolant channel directs fluid to the cutting zone for chip control and heat management
• Left-hand cutting direction with negative rake angle of -14 degrees
• Steel construction provides rigidity across the 180mm overall length
• Conforms to ISO 13399 tooling data standards for compatibility with digital tool management systems

Compatibility

Designed for use with WNM 06T3 series trigon inserts. Compatible insert size code is 06T3. Verify insert designation and coolant supply connection before installation.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down the machine and lock out the spindle before mounting or removing the boring bar. Secure the shank fully within the toolholder to the machine manufacturer's specified clamping depth to prevent deflection during cutting. Confirm coolant supply line connection to the through-coolant port before initiating a cutting cycle.
