Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 5.06mm

Finish holes to exact size with the Magafor Reamer — a spiral-flute, straight-shank tool crafted from HSS-E (M35 cobalt) for reliable wear resistance. With a 5.06 mm nominal diameter, this reamer delivers intermediate-precision bore sizing after drilling, producing smooth, true holes for dependable assemblies.

Designed for engineers, machinists, repair technicians, and hobbyists, it combines efficient material removal with controlled cutting. The left-hand spiral flute paired with right-hand cutting ensures stable, predictable reaming, while the straight shank fits a wide range of chucks and holders. DIN 212-B tolerance: D = 0 + 0.004 mm gives you a consistent final size for tight fits and repeatable results.

• Precise, repeatable bore size: DIN 212-B tolerance of D = 0 + 0.004 mm ensures a true 5.06 mm hole, reducing rework and mating issues.
• Long-lasting HSS‑E with M35 cobalt: Cobalt-enhanced steel resists wear and heat, extending tool life in demanding materials.
• Stable reaming action with straight shank: Left-hand spiral flute and right-hand cutting deliver smooth material removal, while the straight shank fits common chucks and collets for quick setup.

This reamer helps you achieve high-quality bore finishes quickly, promoting efficient workflows, fewer second-pass operations, and reliable fits for assemblies. The true 5.06 mm size, combined with the cobalt-rich HSS-E, provides extended life in tougher materials and reduces tooling costs over time. The straightforward setup and controlled flute design keep runout low, improving consistency across production runs, repairs, and hobby projects alike.
