The 19x300mm Auger Bit is a heavy-duty industrial tool designed for deep-bore penetration in structural timber, bridge construction, and utility projects. With a 19mm diameter, it provides the ideal clearance for structural bolts, plumbing pipes, and heavy-gauge electrical conduits.
Forged from premium High-Carbon Alloy Steel, this bit features a Solid Center Design to provide maximum stiffness. This ensures that throughout the entire 300mm (12-inch) depth, the bit maintains a perfectly straight path without the "deflection" or bending common in lower-quality long-reach bits.

The precision-threaded lead screw acts as a pilot, pulling the 19mm head into the wood automatically. This Self-Feeding mechanism drastically reduces the physical thrust required by the operator, making it efficient for drilling through thick structural beams or multiple stacked joists.
At a 19mm diameter, chip volume is significant. Our Ship Auger Flute design features a deep, open spiral that ejects waste material instantly. This prevents the bit from "locking up" or overheating mid-bore, even when drilling resinous softwoods or pressure-treated lumber.
To handle the massive torque generated by a 19mm cut, the bit is engineered with a Solid Center Core. This provides the torsional strength needed to resist snapping when the bit encounters tough knots or high-density grain in hardwoods like Oak or Jarrah.
The outer spur shears the wood fibers around the circumference before the main lifting edge removes the wood. This results in a Splinter-Free entrance and a smooth-walled hole, ensuring a professional fit for 19mm hardware.

Q: What type of drill is best for this 19mm bit?
A: Due to the high torque of a 19mm diameter, we recommend a High-Torque Rotary Drill with a side handle. While a 1/2" cordless drill can handle it, the side handle is essential for operator safety if the bit hits a knot.
Q: Can this bit be used in "Green" (wet) timber?
A: Yes. The wide-flute ship auger design is specifically intended to clear wet, "stringy" wood chips without clogging, unlike standard twist or spade bits.
Q: Is the 10mm hex shank compatible with my impact driver?
A: Most standard impact drivers use a 1/4" (6.35mm) quick-release. This 19mm bit uses a 10mm reinforced hex shank for strength; you will need a standard 3-jaw chuck or a 10mm hex adapter.
