Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 3.92mm

The Magafor Reamer is an intermediate precision HSS-E straight shank reamer designed to finish drilled holes to an exact size. With a 3.92 mm nominal diameter, it’s ideal for engineers, machinists, workshops, and hobbyists who require reliable, repeatable hole finishing in steel and other alloys. Crafted from HSS-E (M35 cobalt) for enhanced wear resistance, this tool combines durability with precise cutting for longer service life and fewer tool changes.

The reamer features a left-hand spiral flute with right-hand cutting, delivering efficient chip evacuation and a smoother cutting action for consistent hole finishes. It’s designed for compatibility with standard setups thanks to the straight shank, making it easy to drop into existing tooling without special adapters. DIN 212-B tolerance D = 0 + 0.004 mm ensures tight dimensional control for reliable fits and reduced rework.
