The arbor accepts shell reamers ranging from 21\/32 inches to 25\/32 inches in diameter and features a 1\/2-inch diameter straight shank for secure chuck or collet mounting. With an overall length of 9 inches, this arbor provides the reach and rigidity needed for accurate reaming in a variety of bore finishing applications. It is installed by machinists and toolroom technicians working on precision bore sizing in metal fabrication and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis shell reamer arbor is suited for use in drill presses, milling machines, and manual or CNC lathes where controlled bore finishing is required. The No. 4 arbor designation corresponds to standard shell reamer sizing conventions, making it a practical fit for shops that work within the 21\/32-inch to 25\/32-inch bore range.
