MORSE 139014 is a hex shank hole saw arbor with an integral high speed steel pilot drill, designed to drive bi-metal and carbide hole saws in standard drill chucks. The 3\/8-inch hex shank fits any chuck with a 10 mm or larger opening, and the threaded shank attachment uses a 1\/2-20 thread to secure compatible hole saws firmly during use. The arbor body is steel construction for durability under repeated use. This is a direct-drive accessory for electricians, plumbers, HVAC technicians, and general contractors who need reliable hole saw performance in wood, metal, and composite materials.\u003c\/p\u003e\n\u003cp\u003eThe 139014 is suited for residential and light commercial applications where hole saws in the 9\/16-inch to 1-3\/16-inch range are required. Typical install scenarios include drilling knockout holes for conduit, pipe penetrations, and box openings. The hex shank prevents slipping in standard drill and driver chucks, making it a practical replacement or spare arbor for field toolkits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHex shank cross-section prevents rotation and slipping in drill chuck\u003c\/li\u003e\n  \u003cli\u003eIntegral high speed steel pilot drill centers the hole saw before cutting begins\u003c\/li\u003e\n  \u003cli\u003eThreaded shank attachment with 1\/2-20 thread secures hole saws without tools\u003c\/li\u003e\n  \u003cli\u003eCompatible with hole saws ranging from 9\/16 inches to 1-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003eSteel arbor body rated for repeated field use\u003c\/li\u003e\n  \u003cli\u003eMinimum chuck size of 10 mm keeps it compatible with most standard drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 9\/16 inch to 1-3\/16 inch hole saws using a 1\/2-20 threaded attachment.
