Bosch HMD212 Daredevil 2-1/8" Carbide-Tipped Wood Hole Saw
The Bosch HMD212 Daredevil 2-1/8-inch carbide-tipped hole saw bores clean, high-speed holes through 2x dimensional lumber, plywood decking, and engineered wood substrates. Engineered with proprietary Turbo-Teeth technology that delivers up to 5X faster drilling speeds than standard hole cutters, this 2-inch cutting depth core cup features a 2 TPI dual-tooth geometry for rapid material clearance. Outfitted with an all-in-one integrated arbor and pre-installed pilot drill bit on a 1/4-inch hex shank, it equips electricians, plumbers, and residential framing contractors with reliable, clog-free boring performance across hand-held drills and drill presses.
Best Used For:
- Door Lockset and Latch Bore Installation: Drilling standardized 2-1/8-inch cross-bore holes into solid wood entry doors and interior doors without splintering face veneers.
- Electrical Conduit and Pipe Pass-Throughs: Boring wide utility channels through 2x4 and 2x6 framing studs, joists, and structural subflooring in single passes.
- Plumbing Drainage and Vent Rough-Ins: Penetrating thick plywood decking, oriented strand board (OSB), and rough timber quickly without tool binding.
Key Performance & Safety Features
- Turbo-Teeth Carbide Geometry: Dual-tooth carbide-tipped cutting profile slices wood fibers rapidly, yielding up to 5X faster cutting speeds.
- 2-Inch Deep Cup Capacity: Deep-body cup architecture drills completely through standard 2x framing lumber in a single continuous stroke.
- Integrated Arbor and Pilot Assembly: Pre-assembled 1/4-inch hex arbor and pilot bit eliminate the hassle and cost of buying separate mounting hardware.
- Large Side Chip Clearance Slots: Oversized ejection ports facilitate continuous airflow, prevent friction gumming, and allow fast wood plug removal.
- Quick-Change 1/4-Inch Hex Shank: Secures firmly into standard 3-jaw drill chucks and 1/4-inch quick-release adapters without slipping under high torque.
