It features a 5MT (No. 5 Morse Taper) shank for secure seating in compatible spindles and a maximum arbor diameter of 2 inches. The overall length is 16 inches, providing reach and rigidity for precision reaming applications. This arbor bridges the machine spindle and the shell reamer, transmitting torque while maintaining concentricity during the cutting pass. It is a standard toolroom and production machining component installed by machinists and tool-room technicians.\u003c\/p\u003e\n\u003cp\u003eThis arbor is suited for use in manual and CNC milling machines, boring mills, and drill presses equipped with a No. 5 Morse Taper spindle. It accepts shell reamers with a compatible bore range of 3-9\/16 to 4 inches, making it appropriate for finishing large-diameter holes to close tolerances in ferrous and non-ferrous workpieces. Typical applications include production shops, job shops, and maintenance departments where precise bore finishing is required on medium to large components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 12 arbor designation for shell reamers in the 3-9\/16 to 4 inch diameter range\u003c\/li\u003e\n  \u003cli\u003e5MT (No. 5 Morse Taper) shank for direct mounting in compatible spindles without an adapter\u003c\/li\u003e\n  \u003cli\u003e2 inch maximum arbor diameter provides a robust drive interface for large shell reamers\u003c\/li\u003e\n  \u003cli\u003e16 inch overall length offers extended reach for deep bore or offset fixture setups\u003c\/li\u003e\n  \u003cli\u003eStandard arbor number sizing ensures broad compatibility with industry-standard shell reamers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with No. 12 shell reamers having a bore compatibility of 3-9\/16 to 4 inches.

Ensure the machine spindle is fully powered down and locked out before seating or removing the arbor. Clean the Morse Taper shank and spindle socket thoroughly before insertion to ensure full taper contact and prevent fretting.
