Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 4.31mm

The Magafor Reamer is a precision straight shank tool crafted from HSS‑E (M35 cobalt) for durable, reliable hole finishing. Its spiral flute promotes efficient chip evacuation and a smooth cutting action, optimized for applications where hole size accuracy matters. This model is sized at 4.31 mm and features a left-hand spiral flute with right-hand cutting to support controlled reaming in a variety of materials.

Designed to meet DIN 212‑B tolerance requirements, this reamer delivers a bore size tolerance of D = 0 + 0.004 mm, helping you achieve consistent, repeatable results in a single pass. The straight shank ensures robust seating in typical chucks and collets, reducing runout and improving alignment during operation.

• Left-hand spiral flute with right-hand cutting: Delivers controlled cutting and effective chip evacuation for a consistent bore finish and reduced heat buildup.
• HSS‑E (M35 cobalt) construction: Provides enhanced hardness and wear resistance for longer tool life and stable hole diameters, even in tough materials.
• Straight shank for universal compatibility: Easy clamping in standard chucks and collets, delivering reliable alignment and repeatable results across machines.

With this reamer, you gain precise, repeatable bore sizes at 4.31 mm, a cleaner surface finish, and less time spent on rework. The durable HSS‑E material stands up to demanding jobs, while the straight shank and proven geometry keep setup quick and predictable—from prototype runs to high-volume production. Invest in a tool you can trust for consistent results across multiple uses and materials.
