Makita D-47282 12-Piece Electrician’s Bi-metal Hole Saw Set

The Makita D-47282 Electrician's 12-Piece Bi-Metal Hole Saw Kit is designed for cutting clean, round openings during electrical installations and general drilling tasks. This 12-piece bi-metal hole saw set provides tradespeople with the essential components needed to mount junction boxes and conduits. Built with durable bi-metal construction, the attachments handle a wide variety of common job-site materials. These saws are rated for consistent use on metal, aluminium, non-ferrous metals, wood, PVC, and plastic. By supplying the most frequent cutting diameters required for installation work, the kit removes the need to source individual tools separately.

Connecting the cutting attachments to a power tool requires reliable hardware, which is handled by the included drill-driven arbors. The shank design prevents the attachments from slipping within the chuck during heavy drilling tasks. Proper hole clearing is supported by the included hardware, helping users maintain a steady workflow without constant manual unplugging. For transport and organisation between locations, all components arrive in a dedicated carrying case. This rigid storage unit keeps the inventory protected while ensuring quick access across various work sites.

• Nine specific hole saw sizes (19, 22, 29, 35, 38, 51, 54, 57, and 68 mm) accommodate standard conduit and electrical fixture dimensions.
• 38 mm maximum cutting depth allows the tools to penetrate structural timber and thick plastic panels in a single pass.
• Two included adapter arbors enable immediate mounting to standard power drills without requiring additional hardware.
• Hex shank geometry provides a secure grip in the drill chuck to eliminate slippage under heavy torque loads.
• Included eject spring assists in rapidly clearing cut material plugs from the saw interior to maintain operational efficiency.
