A hole saw arbor with a quick-change mechanism that engages and releases threaded hole saws without additional tools. It uses a 135° split-point pilot bit to reduce walking and aid penetration into metal. The pilot bit can be adjusted or replaced without removing the hole saw. The arbor has a no-seize collar to help prevent the hole saw from locking onto the arbor and is made from hardened steel for commercial use.

Creative
Upcycled Can Planter Wall
Create a vertical herb or succulent wall using cleaned metal cans and a pallet backer. Use the quick-change hole saw arbor to cut clean drainage holes and side-mount holes in thin-gauge steel/aluminum cans; the 135° split-point pilot bit prevents skating on curved metal. Quickly swap between hole sizes for drainage, irrigation, and mounting. The no-seize collar helps avoid cans locking to the saw when they heat up, and the adjustable pilot bit lets you fine-tune depth without removing the saw.
Birdhouse Condo With Ventilation
Build a multi-chamber birdhouse from reclaimed lumber. Cut perfect entry holes and ventilation ports through knotty, even nail-embedded wood without destroying bits. The hardened steel arbor handles tough material; the pilot bit’s split point centers cleanly on uneven grain. Rapidly change saw diameters for species-specific entry sizes and removable clean-out caps, speeding up batch production for a neighborhood install or craft fair.
Cable-Grommet Desk Makeover
Turn a thrifted desk into a cable-managed workstation. Use the arbor to cut standard grommet holes in hardwood tops and matching passes through a steel cable tray underneath. The quick-change mechanism lets you switch from wood to metal hole saws in seconds, and the adjustable pilot bit helps avoid punching through too far near delicate veneer. Clean, repeatable cuts make a professional-looking upgrade.
Resin Inlay Charcuterie Boards
Drill precise shallow recesses and through-holes in hardwood boards to create round inlays filled with tinted epoxy. The hole saw plugs become matching coasters or raised feet. The no-seize collar prevents the saw locking onto resin-coated fibers, and the quick-change arbor lets you step through sizes to create concentric rings. The pilot bit can be retracted mid-project to avoid piercing through when you only want a recess.
Portable Speaker Enclosures
Build compact MDF or plywood speaker boxes with accurately sized driver, port, and terminal cup cutouts. The 135° split-point pilot bit minimizes walking on sealed MDF faces, and the quick-change system speeds swapping between driver and port sizes. Use the same arbor to cut accessory holes in metal backplates or grills, keeping tolerances tight and build times short.
