Kyocera THC89652 Indexable Turning Toolholder Adjc

Product Description

The KYOCERA THC89652 is a right-hand, neutral-rake indexable turning toolholder in the ADJC series, designed for precision lathe work in copying and Swiss-type turning applications. Built from steel with a 0.5 inch by 0.5 inch shank and an overall length of 4.75 inches, this toolholder features a 93-degree lead angle and accepts DC-style 325-size inserts secured by a clamp-style insert holding method. The back-of-bar to cutting edge distance is 0.5 inches, and the insert inscribed circle measures 0.375 inches. It is installed by machinists and CNC lathe operators requiring repeatable, rigid insert positioning on right-hand cutting setups.

The THC89652 is suited for copying operations and Swiss-style turning on CNC and manual lathes where a neutral-rake, right-hand toolholder is required. The ADJC series geometry supports controlled chip flow and stable insert seating in tight radial clearance environments. Compatible insert size codes include DCET325, DCGT325, DCGW325, DCMT325, DCMW325, and DCMX325, making this holder versatile across finishing and light-to-medium material removal passes on a range of workpiece materials.

Key Features

• Right-hand cutting direction with neutral rake geometry for balanced cutting forces
• 93-degree lead angle optimized for copying and Swiss turning applications
• Clamp-style insert holding method for secure, repeatable DC-style insert retention
• Accepts six DC 325-series insert geometries: DCET325, DCGT325, DCGW325, DCMT325, DCMW325, DCMX325
• Steel toolholder body for rigidity and durability in production environments
• Multi-use designation supports a range of insert grades and coatings within the compatible size family

Compatibility

Compatible with DC-style 325-series inserts with a 0.375-inch inscribed circle and 0.1563-inch thickness, including DCET325, DCGT325, DCGW325, DCMT325, DCMW325, and DCMX325 insert designations. Designed for use in copying and Swiss-type turning operations requiring a right-hand, neutral-rake ADJC-series toolholder.

Installation Notes

Installation is performed by a qualified machinist or CNC lathe operator. Before mounting the toolholder, ensure the machine spindle is fully stopped, the control is in E-stop or lockout state, and all turret power is de-energized per OSHA lockout/tagout procedures. Secure the shank in the tool turret or holder block to the machine manufacturer's specified clamping torque using calibrated tooling. Do not exceed the insert size or geometry range listed for this holder, as incorrect inserts can cause insert ejection or holder damage during cutting.
