Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 11.83mm

Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 11.83mm is an intermediate precision reamer designed for finishing drilled holes to a precise size. Built from HSS-E (M35 cobalt-rich) steel, this reamer delivers enhanced wear resistance and reliable performance in metalworking. Its straight shank fits standard tool holders, while the left-hand spiral flute and right-hand cutting provide a stable, predictable reaming action that professionals rely on.

The DIN 212-B tolerance of D = 0 + 0.005 mm ensures you achieve a consistently sized hole with minimal post-processing. At 11.83 mm, this tool is sized for common drilling operations and works across a range of materials, making it a versatile choice for engineers, machinists, and workshop setups.

• Durable HSS‑E composition: The cobalt-enriched HSS-E construction offers improved wear resistance and longer tool life, helping you complete more holes between regrinds and reduces downtime.
• Left-hand spiral flute with right-hand cutting: Optimized geometry promotes steady cutting, efficient chip removal, and a smooth finish for reliable hole sizing across multiple passes.
• Tight DIN 212-B tolerance (D = 0 + 0.005 mm): Precise diameter control minimizes oversize and rework, delivering consistent results and better part-to-part interchangeability.

Using this reamer translates to faster, more predictable hole finishing, reduced rework, and improved overall workflow. It pairs durable construction with precise sizing to help you hit spec, stay on schedule, and deliver reliable parts in demanding applications.
