Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 2.53mm

The Magafor Reamer is a precision internal-finishing tool designed to produce exact hole diameters with a smooth, burr-free finish. This 2.53 mm nominal straight-shank reamer is built from HSS-E (M35 cobalt) for added wear resistance and longer life. The tool’s left-hand spiral flute paired with right-hand cutting delivers stable cutting action and efficient chip evacuation for consistent results across materials.

Designed for engineers, machinists, and hobbyists who need reliable hole finishing, it supports quick setups in common tooling stations and helps reduce rework and downtime.

• Tight DIN 212-B tolerance: The tolerance D = 0 + 0.003 mm ensures hole diameters remain within a narrow band, enabling repeatable fits and high assembly reliability.
• HSS-E cobalt composition (M35): Delivers improved wear resistance and longer tool life in challenging materials, reducing replacement costs and downtime.
• Left-hand spiral flute with right-hand cutting: Optimizes chip evacuation and cutting action for clean, consistent holes and smoother finishes, even in tougher workpieces, while the straight shank ensures straightforward mounting in standard collets and chucks.

With the Magafor Reamer, you gain predictable hole size, smoother finishes, and longer tool life. The combination of cobalt-enriched HSS, precise DIN 212-B tolerances, and efficient chip control supports faster setups, less rework, and more consistent results across batches— helping you improve throughput, accuracy, and overall quality in every project.
