Toolex Reamer - Taper Shank - Spiral Flute - Standard Length - HSS - H5 - 25.80 mm End Mill Holders ER40-compatible collet design: Optimized toThis 25. 80 mm taper shank reamer from Toolex uses M2 high speed steel with left hand spiral flutes and right hand cutting edges. It meets BS 328 4 and produces holes to ISO H5 tolerance of 0 to +0. 005 mm for consistent sizing in precision machining work. Spiral flute geometry: Left hand spirals evacuate chips cleanly during right hand cutting to reduce binding and maintain steady feed rates. M2 high speed steel: Retains hardness under heat for
