The Toolex Reamer with straight shank and spiral flute is a precision tool designed for accurate hole enlargement and finishing, ideal for shops and manufacturers that require repeatable, clean bores at 12.70 mm.

• Diameter: 12.70 mm (0.500 in) cutting diameter for precise bore sizing.
• Shank type: Straight shank for reliable clamping in common toolholding systems and easy, versatile setup.
• Flute design: Spiral flute promotes efficient chip evacuation, reducing clogging and improving surface finish.
• Material: HSS-E (high-speed steel with cobalt) delivers increased hardness and heat resistance for demanding materials.
• Applications: Designed for precision hole enlargement and finishing across a range of metals, delivering consistent accuracy and smooth bore quality.

With its robust construction and optimized geometry, this reamer helps you achieve tight tolerances and uniform bore surfaces, minimizing secondary finishing and improving part interchangeability. The spiral-flute design and cobalt-enhanced substrate maintain cutting performance at higher speeds, making it a dependable choice for both resizing existing holes and achieving precise diameters in challenging materials.
