Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 0.87mm

The Magafor Reamer in 0.87 mm diameter is an intermediate precision HSS-E (M35 cobalt) straight shank reamer. Designed to finish internal holes with consistent size and a smooth bore, it’s a reliable choice for machinists, toolmakers, engineers, and hobbyists who require precise hole finishing without guessing at results.

With a left-hand spiral flute and right-hand cutting, this reamer delivers stable, efficient cutting and excellent chip evacuation, helping you achieve a clean, accurate bore. The straight shank design makes it easy to mount in standard chucks, collets, or holders, so you can integrate it quickly into drills, milling machines, or CNC setups.

• Precise DIN 212-B tolerance (+0.003 mm): Ensures hole size stays within a tight, predictable range for repeatable fits and reliable assembly.
• HSS-E (M35 cobalt) for extended tool life: Cobalt-enhanced steel resists wear and heat, delivering longer life and consistent edge performance across multiple jobs.
• Left-hand spiral flute with right-hand cutting on a straight shank: Optimized chip evacuation and stable cutting, plus easy mounting in common equipment for quick, dependable reaming.

Used in production or prototyping, this reamer helps you achieve precise hole sizing, smoother bore finishes, and reduced rework. Its dependable geometry and material composition support consistent results, speeding up setup, improving first-pass accuracy, and extending tool life in everyday metalworking tasks.
