Hertel 1000088 Ctgp Indexable Turning Toolholder

Product Description

The HERTEL 1000088 is a right-hand CTGP-style indexable turning toolholder designed for use on CNC and manual lathes in metal-cutting operations. It features a 0-degree positive rake angle and accepts TP.. 322 series inserts with a 0.375-inch inscribed circle. The shank measures 0.625 inches wide by 0.625 inches tall, with an overall length of 4.5 inches. Constructed from steel, this toolholder suits production turning environments where consistent insert clamping and repeatable tool positioning are required. It is installed by machinists and toolroom technicians on turning centers and engine lathes.

This toolholder is suited for external turning operations on both manual and CNC lathes. The CTGP style uses a clamp-type clamping system to secure trigon-profile inserts. The positive rake geometry reduces cutting forces, making it appropriate for finishing passes and work on lower-rigidity setups or tougher-to-hold workpieces. The back-of-bar to cutting edge dimension is 0.875 inches, and head length is 0.75 inches, allowing clearance planning during setup. No coolant-through capability is present, so external coolant delivery should be accounted for in process planning.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the lathe is fully powered down and the spindle is locked before mounting or removing the toolholder. Torque the tool block clamping screws according to the machine tool manufacturer specifications. Verify insert seating and clamping before initiating any cutting operation.
