Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 5.77mm

The Magafor Reamer with a straight shank and spiral flute is designed for precise bore finishing in metalworking projects. Sized at 5.77 mm, it’s built for intermediate precision tasks and helps you achieve clean, consistent holes in a range of steels and alloys. Equipped with left-hand spiral flutes and right-hand cutting, it delivers controlled material removal for reliable reaming performance.

Made from HSS-E (M35 cobalt-containing) steel, this reamer combines toughness with heat resistance to maintain edge life through multiple jobs. The DIN 212-B tolerance of D = 0 + 0.004 mm ensures your finished holes stay within tight limits, helping you achieve reliable fits and repeatable results with every use.

• Tight tolerance for consistent holes: DIN 212-B tolerance D = 0 + 0.004 mm keeps bore diameters within a tight, predictable range for repeatable fits and minimal finishing work.
• Durable HSS-E (M35 cobalt) construction: High-speed steel with cobalt content resists wear and heat, extending tool life and maintaining sharpness on tougher materials.
• Left-hand flute with straight shank for stability: The left-hand spiral flute and straight shank design provide stable guidance in standard collets and efficient chip evacuation for smoother reaming and reduced downtime.

This reamer helps you finish holes with precision, reducing trial fits and assembly time. The stable straight shank works with common collets, enabling quick changes between operations, while the durable HSS-E edge withstands repeated use in demanding jobs. For engineers, machinists, and hobbyists alike, this tool delivers consistent performance, lower downtime, and dependable results across a range of applications.
