01P009 - Walter 9/16" HSS Bridge Reamer with 1/2" Shank

Precision Hole Alignment with Walter High-Speed Steel Reamers

The Walter 01P009 9/16" Reamer is a premium cutting tool engineered for the demanding requirements of industrial metalworking and structural fabrication. Manufactured in the UK, this reamer is crafted from top-tier High-Speed Steel (HSS), a material chosen for its ability to withstand high temperatures and maintain a sharp cutting edge longer than standard tool steels. This durability makes it an essential asset for professionals who frequently work with tough materials such as stainless steel, mild steel, and aluminum alloys.

Designed with the operator in mind, the reamer features a tapered point that facilitates smooth entry into misaligned or undersized holes. This geometry is critical when aligning bolt holes in structural beams, truck frames, or heavy machinery parts where precision is paramount but initial alignment may be imperfect. Once the tool engages, the sharp spiral flutes efficiently remove material to enlarge the hole to a precise 9/16" diameter, ensuring a perfect fit for fasteners.

One of the standout features of the Walter 01P009 is its shank design. The 1/2" shank is machined with three distinct flats. This triangular profile allows the jaws of a standard drill chuck to grip the tool securely, virtually eliminating the risk of the reamer spinning inside the chuck under high-torque loads. This feature not only protects the tool and the drill but also ensures consistent power transmission for a smoother, safer reaming operation. Whether used in a portable power drill or a magnetic drill press, this Walter reamer delivers reliable performance for maintenance, repair, and operations (MRO) tasks.
