Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 9.17mm

The Magafor Reamer is an intermediate precision HSS-E (M35 cobalt) straight shank reamer designed for finish passes that require tight hole size control. Featuring a left-hand spiral flute and right-hand cutting, it delivers controlled material removal and a smooth, accurate hole finish across a range of metals.

With DIN 212-B tolerance of D = 0 + 0.005 mm, this reamer offers repeatable hole sizes in production and workshop environments. The straight shank provides rigid bite in common drill and milling setups, making it a dependable choice for engineers, machinists, and hobbyists alike.

• Left-hand spiral flute: Efficient chip evacuation and reduced risk of clogging, helping maintain a smooth finish and longer tool life.
• Right-hand cutting action: Predictable material removal and cleaner hole finishes for consistent hole diameters and fewer post-process steps.
• DIN 212-B tolerance and HSS-E cobalt: D = 0 + 0.005 mm tolerance ensures repeatable results; M35 cobalt-enhanced steel delivers improved wear resistance and longer tool life.

By using this reamer, you gain precise control over hole size, faster setup, and reliable results that reduce rework and downtime. The combination of durable HSS-E cobalt alloy and a geometry optimized for smooth cutting helps you achieve repeatable, high-quality finishes even in tougher materials, making it a trusted addition to any metalworking toolkit.
