01P100 - Walter 1-Inch HSS Car Reamer with 3-Flat Shank

Precision Engineering for Industrial Hole Alignment

The Walter 01P100 1" Reamer is a high-performance cutting tool designed to meet the rigorous demands of industrial metalworking and maintenance operations. Manufactured in the United Kingdom, this reamer is crafted from premium High-Speed Steel (HSS), a material selected for its exceptional hardness, wear resistance, and ability to withstand high temperatures during aggressive cutting cycles. Unlike standard carbon steel tools, HSS ensures that the cutting edges remain sharp longer, even when processing tough materials such as stainless steel and structural alloys.

Engineered for precision and efficiency, the 01P100 features a tapered point that allows for self-centering and easy entry into existing holes. This design is critical when aligning overlapping metal plates or enlarging undersized holes to specific tolerances. The flute geometry is optimized to evacuate chips rapidly, reducing heat buildup and preventing binding within the workpiece. This thermal management is essential for maintaining the structural integrity of both the tool and the base material, particularly in heat-sensitive alloys.

A key feature of this tool is its 1/2" shank, which is machined with three distinct flats. In high-torque applications, round shanks often spin within the drill chuck, leading to damage to the equipment and the tool itself. The 3-flat design provides a positive lock within the chuck jaws, ensuring 100% torque transmission from the power tool to the cutting edge. This feature makes the Walter 01P100 compatible with a wide range of heavy-duty hand-held electric and pneumatic drills commonly found in MRO environments.

Applications for this reamer are extensive, covering the enlargement and alignment of holes in aluminum, mild steel, and stainless steel. It is an indispensable asset for fabrication shops, structural steel erection, and heavy machinery repair, where bolt hole alignment is a frequent necessity. By combining superior metallurgy with practical design features, Walter Surface Technologies delivers a reaming solution that enhances productivity and reduces tooling costs over time.
