Morse 139069 Hole Saw Arbor 6 in Hex Shank","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe M.K. MORSE 139069 is a hole saw arbor designed to drive hole saws ranging from 1-1\/4 to 6 inches in diameter. It features a 7\/16-inch hex shank and a quick-change attachment method that allows fast tool swaps without additional hardware. An integrated high speed steel pilot drill centers the saw before cutting begins, reducing walking and improving cut accuracy. The arbor threads at 5\/8-18 and requires a minimum chuck size of 11 mm. It is built from steel for durability under repeated use. Licensed tradespeople and experienced contractors use this arbor with compatible bi-metal or carbide hole saws in drilling applications across multiple trades.\u003c\/p\u003e\u003cp\u003eThis arbor is suited for use in residential and light commercial installation work where large-diameter holes are required. Typical applications include drilling through wood framing, drywall, and similar substrate materials for HVAC ducting penetrations, plumbing rough-in, and electrical conduit runs. The quick-change design is particularly useful when alternating between multiple saw diameters on a single job. The hex shank seats securely in standard drill chucks and impact-rated drivers that meet the 11 mm minimum chuck requirement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAccepts hole saws from 1-1\/4 to 6 inches in diameter\u003c\/li\u003e\n\u003cli\u003e7\/16-inch hex shank with quick-change attachment for fast bit swaps\u003c\/li\u003e\n\u003cli\u003eIntegrated high speed steel pilot drill for accurate centering\u003c\/li\u003e\n\u003cli\u003e5\/8-18 thread size for standard hole saw compatibility\u003c\/li\u003e\n\u003cli\u003eSteel arbor body for durability under repeated load cycles\u003c\/li\u003e\n\u003cli\u003eRequires minimum 11 mm chuck — compatible with most full-size drills\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with hole saws from 1-1\/4 to 6 inches in saw diameter.
