Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 8.46mm

The Magafor Reamer – Spiral Flute, Straight Shank, HSS-E (M35 Cob) – 8.46 mm is an intermediate‑precision tool designed to finish holes to a precise size with reliable, repeatable results. Its straight shank fits standard chucks and setups, while the left‑hand spiral flute with right‑hand cutting delivers efficient chip control and stable cutting for high‑quality holes in a range of materials.

Tolerances follow the DIN 212‑B standard, with a size tolerance of D = 0 + 0.005 mm, so you can trust the finished hole to stay within specification in production runs and reduce the need for secondary finishing.

• Tight DIN 212-B tolerance for consistent holes: Finishes holes to D = 0 + 0.005 mm, reducing rework and ensuring reliable interchangeability across parts.
• Durable HSS-E (M35 cobalt) material: Offers improved wear resistance and edge retention for longer tool life and fewer sharpenings under demanding materials and speeds.
• Left-hand spiral flute with right-hand cutting: Optimizes chip evacuation and delivers stable, predictable cutting for smoother finishes and less downtime.

With this reamer, you get precise, repeatable finishes beyond a single pass, faster setup times, and reduced downtime. The robust HSS-E construction and straightforward straight-shank design integrate easily with standard drilling and reaming stations, whether you’re using a manual setup or a CNC machine. This means higher consistency across parts, less rework, and better overall surface quality for your projects.
