Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 4.40mm

The Magafor Reamer is an intermediate precision tool designed to finish drilled holes to a precise diameter. With a straight shank and HSS‑E (M35 Cob) steel, it delivers durability and dependable performance in metalworking. Its left‑hand spiral flute and right‑hand cutting work together to provide controlled material removal and a smooth, accurate hole finish.

This 4.40 mm nominal reamer is built for engineers, machinists, and hobbyists who need consistent hole sizes across multiple parts. The DIN 212‑B tolerance of D = 0 + 0.004 mm ensures minimal oversize variation, enabling reliable fits and repeatable results in everyday machining tasks.

• HSS‑E material for long life: Made from cobalt‑enhanced high‑speed steel for sharp edges and extended tool life even in tougher materials.
• Left‑hand spiral flute with right‑hand cutting: Optimized geometry promotes efficient cutting and smooth chip evacuation for a clean, consistent finish.
• Tight DIN 212‑B tolerance (D = 0 + 0.004 mm): Delivers reliable, repeatable hole sizes that fit mating parts with confidence.

Use this reamer with appropriate support and cutting fluid to maximize performance. It helps reduce rework, speeds setup times, and delivers repeatable hole quality—making it a dependable addition to any precision machining toolkit.
