Hertel 1000134 Msdn Neutral Turning Toolholder 0.5in Shank

Product Description

The HERTEL 1000134 is a neutral-hand MSDN-style indexable turning toolholder designed for negative rake metal cutting operations. It accepts SN..32. series inserts secured by a combination clamp and screw holding method, providing rigid, repeatable insert location during turning passes. The shank measures 0.5 x 0.5 inches with an overall length of 4.5 inches, fitting standard toolpost setups on CNC and manual lathes. With a rake angle of -7 degrees and steel construction, this holder is built for consistent performance in high-feed roughing and finishing applications across a range of workpiece materials.

This toolholder is suited for external turning operations on CNC turning centers and manual engine lathes where a neutral-hand approach is required. The MSDN configuration positions the insert for straight-line cuts and facing operations. It is installed by machinists and CNC setup technicians working in production shops, job shops, and toolrooms. The back of bar to cutting edge dimension of 0.25 inches keeps the cutting edge close to centerline for precise depth-of-cut control.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the lathe spindle before changing inserts or mounting the toolholder in the turret or toolpost. Ensure the shank seating surfaces are clean and free of chips before tightening. Follow the machine manufacturer torque and clamping specifications for toolpost or turret pocket fasteners.
