Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 4.44mm

Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 4.44mm is an intermediate precision tool designed to finish holes with reliable size and a clean surface. It’s ideal for engineers, machinists, and workshop technicians who need consistent hole accuracy and a smooth final bore.

Crafted from HSS-E (M35 cobalt) with a straight shank, this reamer pairs durability with heat resistance for longer life in demanding materials. The left-hand spiral flute works with right-hand cutting to promote stable engagement and efficient chip evacuation, helping you achieve precise bores with fewer passes. DIN 212-B tolerance D = 0 + 0.004 mm ensures the hole size stays within tight, repeatable limits.

• HSS-E (M35 Cobalt) durability: Boosts wear resistance and cutting life for reliable performance in tougher metals, helping you finish more holes per tool.
• Left-hand spiral flute with right-hand cutting: Enhances chip flow and cutting stability, delivering a smoother surface finish and fewer deflections during reaming.
• DIN 212-B tolerance: D = 0 + 0.004 mm: Delivers consistent hole sizes across jobs, reducing rework and ensuring dependable mating with components.

Used correctly, this reamer improves workflow by delivering repeatable bore quality, cutting downtime, and enabling accurate assemblies right out of the fixture. Its straight shank fits standard holders and tooling setups, making it a practical upgrade for both production environments and precision-focused projects.
