Hex Shank Auger Drill Bit for Woodworking

Technical Data

1. Material & Processing: The main body is mostly made of heat-treated high-carbon steel, and high-speed steel is an option for high-end models. It undergoes full-length heat treatment and precision grinding processes.
2. Key Dimensions: The common diameter ranges from 6mm to 40mm, and the overall length has multiple specifications such as 230mm, 460mm, 500mm, and 600mm. For example, there are models like 25mm×460mm and 8mm×165mm. The hex shank often adopts a 6.35mm or 1/4-inch quick-change specification, which fits most power tool chucks.
3. Structural Traits: It is equipped with a screw-threaded center point or brad point tip for accurate positioning. The flute types are diverse, including single flute (with or without stem), double flutes, three flutes, and four flutes. Most models have single or multiple spur cutting edges, and some four-flute versions adopt a tapered design to optimize chip removal.
4. Applicable Scope: It is suitable for drilling holes in softwood, hardwood, plywood, chipboard, and even creosoted poles. It can also be used for plastic and aluminum alloy materials in some cases.

Advantages

1. Firm Clamping & Anti-slip: The hex shank design avoids spinning or slipping in the drill chuck during high-torque drilling, which ensures stable power transmission. The 1/4-inch quick-change hex shank can be quickly connected to matching chucks, saving the time of replacing bits.
2. Efficient Drilling & Clean Holes: The screw-threaded center tip enables self-feeding during drilling, reducing manual pushing force. The spur cutting edges minimize splintering of the wood during drilling.
3. Strong Durability
4. Strong Versatility & Convenience.
