Hertel 1000163 Left Hand Mtfn Indexable Turning Toolholder

Product Description

The HERTEL 1000163 is a left-hand MTFN-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built from steel with a 3/4 inch by 3/4 inch square shank and an overall length of 4.5 inches, it accepts TN..33. series triangular inserts secured by a clamp and screw holding method. The negative rake angle of -5 degrees promotes edge strength and is well suited for interrupted cuts and harder workpiece materials. Installation and indexing are straightforward, making this a reliable choice for production turning environments. Machinists and CNC lathe operators working in job shops or manufacturing facilities are the primary installers.

This toolholder fits standard MTFN left-hand turning applications where the tool approaches the workpiece from the right side of the turret. The 3/8 inch insert inscribed circle and the back-of-bar to cutting edge distance of 1 inch provide predictable tool offset geometry for programming. It is suited for both roughing and finishing passes depending on insert grade and geometry selection. No coolant-through capability is present, so external flood or mist coolant delivery should be planned at the machine level.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine before mounting or changing toolholders in the turret. Torque the insert clamp screw to the insert manufacturer's specification using the appropriate torx or hex key. Verify tool offset and edge height to centerline before resuming cutting operations.
