01P010 - Walter 5/8-Inch HSS Car Reamer with 1/2-Inch Shank

Precision UK-Made High-Speed Steel Reamer

The Walter 01P010 5/8" Reamer represents the pinnacle of hole-alignment technology, manufactured with exacting standards in the United Kingdom. Designed for professional machinists and industrial maintenance teams, this tool is crafted from premium High-Speed Steel (HSS). The choice of material ensures that the cutting edges maintain their sharpness even under the high thermal loads generated during the reaming of tough alloys like stainless steel and structural steel. Unlike standard drill bits that may wander or chatter, this reamer is engineered to follow an existing pilot hole or misalignment, shaving the material precisely to achieve a clean, 5/8-inch diameter aperture.

One of the critical engineering features of this model is its shank design. The 1/2-inch shank is compatible with a wide range of standard industrial drill chucks. However, Walter has gone a step further by machining three distinct flats onto the shank. This tri-flat geometry creates a positive lock within the chuck jaws, effectively eliminating the frustration of the tool spinning inside the chuck under high-torque conditions. This feature not only protects the tool and the drill but also ensures consistent power transmission from the motor to the workpiece, resulting in smoother cuts and reduced operator fatigue.

The tapered nose of the reamer is specifically designed to facilitate entry into holes that are slightly undersized or misaligned—a common occurrence in multi-layer assembly and riveting tasks. As the tool advances, the spiral flutes engage the material, efficiently evacuating chips and reducing the risk of binding. Whether you are working on precision machinery repair, structural framework, or general metalworking projects, the Walter 01P010 delivers the reliability and performance required for high-stakes industrial environments.

Key Technical Benefits:

• Superior Metallurgy: Premium HSS construction resists heat and wear.
• Secure Grip: 3-flat shank design prevents chuck slippage.
• Versatile Application: Effective on aluminum, steel, and stainless steel.
