Hertel 1000136 Msdn Neutral Indexable Turning Toolholder

Product Description

The HERTEL 1000136 is a neutral-hand MSDN-style indexable turning toolholder designed for negative rake lathe operations in metal cutting environments. Built from steel, it accepts SN..32. series inserts held in place by a clamp and screw system. The shank measures 0.75 inches wide by 0.75 inches tall with an overall length of 4.5 inches, making it a compact, rigid platform for external turning on manual and CNC lathes. Machinists and tool and die professionals working in production or job-shop settings will find this holder a direct fit for standard square-shank toolpost systems.

This toolholder is suited for external turning applications where a neutral hand orientation is required — meaning the cutting edge is centered and the holder can be used without a left- or right-hand preference. The negative rake angle of -7 degrees promotes edge strength and is well matched to harder workpiece materials and interrupted cuts. It fits into standard square or rectangular toolpost setups on engine lathes and turning centers. The insert inscribed circle measures 0.375 inches, consistent with the SN..32. insert family.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians.

Power down and lock out the machine before changing inserts or repositioning the holder. Follow the lathe or turning center manufacturer guidelines for toolpost clamping procedure.
