When you need precise hole finishing, this reamer delivers reliable, repeatable results. The ISO H5 tolerance paired with DIN 212-B ensures holes that fit mating parts with minimal play. The M2 HSS geometry provides robust wear resistance for multiple reaming passes, while the straight shank and compatible holders simplify setup. The left-hand spiral flute aids chip evacuation in typical reaming operations, contributing to a cleaner bore and reduced burrs. Used after drilling, it helps achieve a consistent bore diameter and smooth internal surfaces, reducing rework and finishing time. The tool is manufactured to order, with a 24–48 hour despatch window to fit production schedules. If you see "in stock," that label refers to blanks ready to be machined into the final reamer.
