Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 0.91mm

The Magafor Reamer is an intermediate-precision finishing tool designed to bring drilled holes to an exact diameter with repeatable results. Sized at 0.91 mm, this straight-shank reamer is ideal for finishing small-bore holes in a variety of materials and applications, from precision prototypes to production parts.

Constructed from HSS-E (M35 cobalt) and featuring a left-hand spiral flute with right-hand cutting, it delivers stable cutting action, reliable hole quality, and longer life under demanding use. The DIN 212-B tolerance of D = 0 + 0.003 mm ensures you can hit tight size targets and maintain precise fits in assemblies.

• Tight DIN 212-B tolerance: Holes finish to D = 0 + 0.003 mm for consistent fit and repeatable quality.
• HSS-E (M35 cobalt) composition for durability: The cobalt-enriched alloy improves wear resistance and heat tolerance, extending life in steel, stainless steel, and tougher alloys.
• Straight shank with left-hand spiral flute and right-hand cutting: Provides stable clamping, efficient chip removal, and a predictable, smooth finish in small-bore reaming tasks.

Using this reamer helps you achieve precise, reliable hole sizes, reducing post-processing needs and variation across parts. The robust construction and compatibility with standard tooling mean you can rely on consistent results in both production and project work, improving workflow and part quality over time.
