Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 3.76mm

The Magafor Reamer is a 3.76 mm diameter, straight shank reamer designed for reliable hole finishing on a variety of materials. Built from HSS-E (M35 cobalt), this tool delivers intermediate precision with a geometry optimized for clean, accurate holes. It features a left-hand spiral flute paired with right-hand cutting, which aids chip evacuation and helps maintain stable cutting conditions during reaming.

Engineered for sturdy performance in shop environments, this reamer adheres to DIN 212-B tolerances, offering a defined hole size with a tolerance of D = 0 + 0.004 mm to support consistent results in production or prototype work.

• Left-hand spiral flute with right-hand cutting: Efficient chip removal and stable cutting produce a smooth, round hole with minimal chatter, even in longer reams.
• Straight shank in HSS-E (M35 cobalt): Rigid, reliable fit in collets and chucks with excellent wear resistance for longer tool life in demanding materials.
• DIN 212-B tolerance: D = 0 + 0.004 mm: Tight, predictable hole size that reduces finishing work and ensures repeatable results across parts.

With its precise geometry and robust construction, this Magafor reamer helps you finish holes of consistent size quickly and confidently. The combination of a straight shank, left-handed flute, and cobalt-rich HSS stands up to frequent use in metalworking, delivering reliable results, fewer rework cycles, and smoother downstream assembly.
