Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 0.64mm is an intermediate precision finishing tool designed to bring drilled holes to final size with a smooth, burr-free bore. Built for engineers, machinists, and hobbyists, it provides reliable, repeatable hole quality in a compact 0.64 mm diameter. The straight shank and left-hand spiral flute with right-hand cutting support stable cutting and effective chip control for consistent results. Crafted from HSS-E (M35 Cob) cobalt alloy, this reamer delivers enhanced wear resistance and long life even in demanding finishing work. It adheres to DIN 212-B with a tolerance of D = 0 + 0.003 mm, ensuring the final hole size stays within tight dimensional limits for dependable interchangeability in assemblies. Tight DIN 212-B tolerance (D = 0 + 0.003 mm): Delivers precise bore size for reliable assemblies and repeatable results. Durable HSS-E cobalt construction (M35 Cob): Offers improved wear resistance and tool life in challenging finishing applications. Straight shank for secure mounting: Easy, stable setup in standard chucks and collets, promoting consistent alignment and reduced runout. This reamer helps you achieve accurate final holes with a clean finish, reduces the need for rework, and supports efficient workflows across manufacturing, fabrication, or prototyping environments. Rely on its consistent performance to produce precise components quickly and with fewer adjustments.
