Boring large-diameter holes in timber requires the Tolsen 38mm Flat Wood Bit 75649. Hardened carbon steel prevents the spade from warping under friction heat. With a 1/4-inch hex shank, the bit secures into quick-change chucks without slipping. Spade geometry clears waste material during deep drilling.
Key Features
- 1/4" Hex Shank: With quick-release geometry, this fits impact drivers and standard chucks. Swap bits fast without using a chuck key.
- Polished Surface: Through a precision ground finish, friction stays low during boring. Cuts cleaner holes with less surface splintering.
- Hardened Carbon Steel: Using heat-treated metal alloy, cutting edges stay sharp longer. Resists surface corrosion in high humidity storage.
- 38mm Spade Width: At a fixed paddle size, it creates wide conduit openings. Clears wood chips efficiently to prevent stalling.
