Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 12.25mm

The Magafor Reamer with a spiral flute and straight shank is designed for finishing internal holes with consistent, precise diameters. Its left-hand spiral flute and right-hand cutting deliver efficient material removal and smooth bore finishes, making it a reliable choice for engineers, machinists, hobbyists, and workshop professionals working on steel, cast iron, and alloys.

Manufactured from HSS‑E (M35 cobalt) for superior wear resistance and heat tolerance, this 12.25 mm reamer is built to withstand demanding reaming tasks. It conforms to DIN 212-B tolerance with D = 0 + 0.005 mm, delivering a reliable, repeatable bore size with minimal rework. The straight shank simplifies mounting in common chucks and collets, while the spiral flute enhances chip control for cleaner finishes.

• Premium HSS‑E (M35) material: Delivers improved wear resistance and heat tolerance for longer tool life in tough steels and alloys.
• Left‑Hand Spiral Flute with Right‑Hand Cutting: Optimizes cutting action and chip evacuation to reduce chatter and produce smoother bores.
• DIN 212‑B tolerance (+0.005 mm): Ensures precise bore size with minimal rework, supporting consistent fits across parts.

Together, these features provide a dependable, efficient reaming solution that helps you achieve accurate, repeatable bore finishes with fewer passes and less downtime. Ideal for production runs or precision assemblies, this reamer supports steady workflow and reliable results across a range of materials and applications.
