The 10x300mm Auger Bit is an essential tool for deep-bore applications in structural timber, log home construction, and heavy-duty landscaping. With a total length of 300mm (approx. 12 inches) and a precise 10mm diameter, it is perfectly sized for M10 structural bolts, threaded rods, and standard wiring conduits.
Forged from high-carbon alloy steel and featuring a Solid Center design, this bit provides the rigidity required to drill perfectly straight holes through thick joists and beams without the "wandering" common in standard twist bits.

Self-Feeding Lead Screw
The precision-machined threaded tip pulls the bit into the wood automatically. This Self-Feeding action allows for rapid penetration with minimal manual effort, significantly reducing operator fatigue during repetitive drilling on high-volume job sites.
Solid Center "Ship Auger" Geometry
The solid center core provides exceptional torsional strength. This ensures the bit remains stable and rigid throughout the 300mm depth, preventing bending or snapping even when encountering high-resistance knots in hardwoods.
Turbo Chip Evacuation
The wide, deep-spiral flute is designed to eject wood chips instantly. This prevents "Dust Packing" and friction heat, allowing the bit to remain cool and sharp for extended service life in both dry and "green" (wet) lumber.
Clean-Cut Single Spur
The sharpened outer spur scribes the circumference of the hole before the main cutting edge engages. This results in a smooth, circular hole wall and a Clean Exit with zero splintering, which is critical for the aesthetic finish of visible timber joints.
Structural Joinery: Precision boring for M10 bolts and threaded rod installations in timber framing.
Electrical Rough-in: Creating clean 10mm channels through multiple studs and floor joists for heavy-duty wiring.
Landscaping: Efficiently drilling through pressure-treated 4x4 posts and retaining wall timbers.
Cabinetry & Furniture: Deep-hole drilling for specialized concealed fasteners and structural dowels.

Q: Can I use this 10mm bit in a standard impact driver?
A: Yes. The 6.35mm (1/4") hex shank is specifically designed for quick-change compatibility with all professional impact drivers and cordless drills.
Q: Is the 300mm length suitable for drilling through 4x4 or 6x6 posts?
A: Absolutely. With a 230mm working flute length, this bit can easily penetrate a standard 4x4 (90mm) or 6x6 (140mm) post in a single pass with room for chip clearance.
Q: How do I sharpen the bit after heavy use?
A: The single spur and cutting edge can be easily sharpened using a small feather file. Avoid filing the outer diameter to maintain the 10mm precision.
