Hertel 1000104 Mcln Indexable Turning Toolholder 1x1 Shank

Product Description

The HERTEL 1000104 is a right-hand MCLN-style negative rake indexable turning toolholder designed for use on CNC lathes and manual turning centers. It features a 1 inch by 1 inch square shank and an overall length of 6 inches, making it a standard size for tool turrets and square-shank toolposts. The holder uses a clamp and screw holding method to secure CN-type inserts with a 0.375 inch inscribed circle, providing secure seating and consistent cutting edge presentation. Built from steel, it is suited for production turning operations where dimensional stability and insert repeatability matter. Licensed machinists and CNC operators install this holder as part of a turning tool station setup.

This toolholder is applicable in metalworking environments where negative rake CN-style inserts are the specified cutting geometry. The 5-degree lead angle and 1.25 inch back-of-bar to cutting edge dimension suit general-purpose external turning and facing operations. It is commonly used in job shops and production facilities running steel, stainless, and cast iron workpieces on engine lathes, turret lathes, and CNC turning centers. The MCLN style accommodates a range of depths of cut typical of roughing and semi-finishing passes.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the lathe spindle before mounting or removing the toolholder from the turret or toolpost. Ensure the shank seating surfaces are clean and free of chips before tightening. Follow the machine tool manufacturer's recommended clamping torque and toolholder projection guidelines to avoid chatter or insert breakage.
