Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 12.45mm

Toolex Reamer, Straight Shank, Spiral Flute, Carbide, H5, 12.45mm, is a precision hole-finishing tool designed for engineers, machinists, and hobbyists who demand clean, repeatable sizes. The 12.45 mm diameter model uses K10 intermediate precision carbide for improved wear resistance and stable cutting, and its left-hand spiral flute with right-hand cutting follows the DIN 212 B-inspired geometry to deliver accurate holes to ISO H5 tolerance. With a six-flute configuration and a straight shank, it works in standard collets and toolholders for reliable performance in production or setup work.

Manufactured to order, this reamer is dispatched within 24–48 hours to ensure you get a fresh tool tailored to your job. The Toolex design prioritizes consistent finishes, predictable sizing, and durable service life, making it suitable for demanding applications in steel, cast alloys, and other common machinable materials.
