Hertel 1000091 Lh Ctgp Indexable Turning Toolholder

Product Description

The HERTEL 1000091 is a left-hand CTGP-style indexable turning toolholder designed for precision external turning operations on CNC lathes and manual turning centers. Built from steel with a clamp-type insert retention system, this toolholder accepts TP..32. series inserts and features a 0-degree positive rake angle geometry. The shank measures 0.625 inches wide by 0.625 inches tall with an overall length of 4.5 inches. The positive rake configuration reduces cutting forces and is well suited for finishing passes on softer workpiece materials. Licensed machinists and CNC operators specify this holder for reliable, repeatable insert indexing in production turning environments.

This toolholder is intended for use in turning applications where a left-hand cutting direction is required, such as facing toward a tailstock or turning toward a shoulder from right to left. The CTGP style is a standard clamp-type geometry used in both job shop and production turning on lathes with appropriate tool post or turret mounting. The 3/8-inch insert inscribed circle and 0.875-inch back-of-bar to cutting edge dimension suit it for moderate depth-of-cut operations on a variety of workpiece materials.

Key Features

• Left-hand cutting orientation for right-to-left turning and facing operations
• CTGP toolholder style with clamp-type insert retention for secure, repeatable indexing
• Accepts TP..32. series inserts with a 3/8-inch inscribed circle
• 0-degree positive rake angle reduces cutting forces on lighter cuts and finishing passes
• Steel construction for rigidity and durability in production turning environments
• Compact 4.5-inch overall length suits tight clearance setups

Compatibility

Designed for use with TP..32. series indexable turning inserts. Verify turret or tool post bore and mounting dimensions match a 0.625 x 0.625 inch shank before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or removing any toolholder. Ensure the tool post or turret pocket is clean and free of chips before seating the shank. Torque all clamping fasteners according to the machine tool manufacturer's specifications, not the toolholder manufacturer's specifications unless explicitly provided.
