The SECO 02823301 is an external right hand indexable grooving toolholder from the X4 Jet series, designed for precision grooving operations on CNC lathes and turning centers. It accepts X4GK25..R inserts held by a clamp-style insert holding method, providing secure, repeatable cutting performance. The toolholder features through-coolant capability, directing fluid directly to the cutting zone to control heat and extend insert life. It handles a maximum depth of cut of 0.256 inches and accommodates groove widths from 0.031 inches to 0.118 inches. The 1 inch by 1 inch shank and 6 inch overall length suit a broad range of turning center setups. Machining of cast iron is identified as the primary application.
This toolholder is suited for external, non-face grooving applications in production and job-shop turning environments. The X4 Jet toolholder style integrates through-coolant delivery, making it well matched to high-volume operations where heat management and chip evacuation are critical. Its right-hand cutting direction and right-hand holder orientation make it appropriate for standard front-turning configurations. Machinists and CNC programmers working on cast iron components will find the toolholder particularly relevant, though its insert and clamping system support a range of grooving tasks.
Designed to accept X4GK25..R inserts with compatible insert size code X42503R. Also referenced under manufacturer number X4FR/L 1002503DJET. Verify machine coolant pressure and connection specifications before installation.
Installation should be performed by a qualified machinist or CNC setup technician. Shut down and lock out the machine spindle before mounting or adjusting the toolholder. Confirm the through-coolant port is properly connected to the machine's coolant supply before operation. Follow the machine tool manufacturer's guidelines and applicable shop safety procedures when setting tool offsets and securing the shank in the turret.
