Auger Bit Drill 22mm L600mm for Precise Woodworking

The Alpen Series 228 Auger Bit is engineered to deliver centered, clean holes in deep wood joins, especially when working with square timbers and wood jambs. With a 22 mm diameter and a 600 mm overall length, this bit powers through long runs in a single pass, reducing setup time and improving consistency across multiple joints.

Why this long-reach auger stands out

Designed for precision in demanding joinery, the 228’s long reach (600 mm) lets you drill deep into frames, posts, and thick timber without constantly repositioning your workpiece. This capability is particularly beneficial for door frames, window jambs, cabinetry supports, and framing members where alignment and depth control matter most.

Centering, accuracy, and clean holes

A highly accurate tip alignment keeps the bit on center from start to finish, minimizing drift when drilling dense or tight-grain timbers. Coupled with sharp cutting edges, it produces crisp, tear-out–free holes in a range of woods, including hardwoods, which is essential for precise dowel placement and reliable hardware installation.

Key features at a glance

• Diameter: 22 mm
• Length / Reach: 600 mm total length for deep drilling
• Centering alignment: Maintains true bore axis to reduce wandering
• Cutting edges: Sharp for clean holes and tight tolerances

Practical use and best practices

Secure the workpiece firmly, align the bit with your center mark, and drill at a steady, controlled pace. Clamp to prevent deflection during the 600 mm reach, and use gradual feed to maintain accuracy and minimize tear-out. For projects that require consistent results across multiple holes, keep a constant speed and pressure, and periodically verify alignment with a square or center guide.
