Iscar 3800029 Threading Toolholder 1x1 Inch Shank Ser

Product Description

The ISCAR 3800029 is an indexable threading toolholder designed for external threading operations on CNC lathes and manual turning centers. Built to the SER series standard, this right-hand toolholder accepts an M 16 insert held in place by a screw-clamp method, providing rigid and repeatable insert positioning. The shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches, making it a compact, direct-mount option for standard tool blocks and quick-change turrets. Coolant-through capability is not included on this model. This toolholder is specified by machinists and CNC operators in production and job-shop environments.

This toolholder suits external threading applications on ferrous and non-ferrous workpieces in both production and repair-shop settings. The 1 x 1 inch shank fits standard OD toolholding stations on most engine lathes and CNC turning centers that accept square-shank toolholders. The SER series designation identifies the insert seat geometry and the type of threading inserts compatible with this holder. The back-of-bar to cutting-edge dimension is 1 inch, which determines offset when setting tool height to centerline.

Key Features

• External threading application with right-hand cutting orientation
• Screw-clamp insert holding method for secure, repeatable insert seating
• Accepts M 16 threading inserts with a 3/8 inch inscribed circle
• 1 x 1 inch square shank fits standard turning-center tool blocks
• 6 inch overall length provides clearance in typical OD turning setups
• No-coolant configuration keeps setup simple where coolant-through is not required

Compatibility

Designed to accept M 16 series threading inserts with a 3/8 inch inscribed circle. Compatible with standard square-shank toolholding stations that accept a 1 x 1 inch shank profile.

Installation Notes

This toolholder is installed by machinists and CNC lathe operators. Before mounting, power down and lock out the machine per OSHA lockout-tagout procedures. Verify shank seating is fully engaged in the tool block before tightening the clamping fasteners. Set tool centerline height carefully before threading — off-center height on a threading pass will affect thread form geometry. Replace or index the insert when chipping or surface-finish degradation is observed.
