CAT50 Tool Holders

CAT50 Tool Holders — New & Used

CAT50 tool holders are built for heavy-duty milling and high-rigidity machining on large-frame CNC machines. With a steep-taper 7/24 interface and robust flange design, CAT50 delivers superior pull-force retention, runout control, and vibration damping in demanding roughing and high-metal-removal-rate applications. We stock popular holder styles—ER collet chucks, end mill/side-lock, shell/face mill arbors, mill/ream chucks, tapping, and drill chucks—plus pull studs, collets, and accessories to complete your spindle setup.

At Surplus Select, our rotating inventory of new and used OEM CAT50 holders includes trusted brands like Kennametal, Sandvik Coromant, Lyndex-Nikken, Techniks, Parlec, and MariTool. Listings update daily, offering surplus pricing for MRO replacements, new setups, and capacity expansions.
