01P005 - Walter 5/16-Inch High-Speed Steel Aligning Reamer

Precision Alignment with Walter High-Speed Steel Reamers

The Walter 01P005 5/16" Reamer is a premium-grade cutting tool designed for the demanding requirements of industrial metalworking and maintenance operations. Manufactured in the United Kingdom, this tool represents the pinnacle of high-speed steel (HSS) engineering, offering exceptional hardness and heat resistance. It is specifically crafted to solve one of the most common challenges in fabrication and assembly: misaligned holes. Whether working with structural steel, stainless steel plate, or aluminum components, this reamer effortlessly enlarges and aligns overlapping holes to facilitate bolt insertion and secure fastening.

One of the standout features of this reamer is its intelligent shank design. The 3/8" shank is engineered with three precision-ground flats. This tri-flat geometry is critical for high-torque applications, as it allows the jaws of a standard hand-held drill chuck to grip the tool securely, preventing the slippage that often occurs with round shanks. This ensures maximum power transmission from the drill to the cutting edge, improving efficiency and safety for the operator. The tapered point of the reamer acts as a pilot, guiding the tool into the hole center even when misalignment is present, allowing for smooth, chatter-free cutting action.

Durability is at the core of the Walter product line. The high-quality HSS material retains its cutting edge longer than standard carbon steel tools, reducing downtime for tool changes and sharpening. This reamer is an essential asset for MRO (Maintenance, Repair, and Operations) professionals, steel erectors, and heavy equipment mechanics who require reliable tools that perform consistently in tough environments. By choosing the Walter 01P005, you are investing in a tool that delivers precision, speed, and longevity, ensuring your projects are completed to the highest standards.
