Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 4.85mm

The Magafor Reamer is an intermediate precision tool designed to fine‑tune hole diameters with dependable accuracy. Crafted from HSS‑E (M35 cobalt steel) and featuring a straight shank, it pairs easy mounting with reliable performance across a range of machining setups.

With a left‑hand spiral flute and right‑hand cutting, this reamer promotes efficient chip control and a smooth hole finish. The 4.85 mm diameter is held to DIN 212‑B tolerance (D = 0 + 0.004 mm), delivering repeatable results you can trust in production and workshop environments.

• DIN 212‑B Tolerance you can trust: Keeps hole size within D = 0 + 0.004 mm for consistent fits and fewer rework cycles.
• Efficient chip control with left‑hand spiral: Left‑hand flute paired with right‑hand cutting improves chip evacuation and surface finish across a variety of materials.
• Durable HSS‑E with a straight shank: M35 cobalt alloy offers enhanced wear resistance and heat tolerance, while the straight shank ensures straightforward mounting in common tooling and fixtures.

This reamer helps you achieve precise, repeatable holes quickly, improving workflow by reducing trial passes and post‑drilling finishing. Ideal for mid‑volume production, maintenance, and general machining tasks where hole accuracy matters.
