Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 5.55mm

The Magafor Reamer is an intermediate precision HSS-E (M35 Cob) straight shank reamer designed to finish holes with tight, repeatable accuracy. Its 5.55 mm diameter and DIN 212-B tolerance of D = 0 + 0.004 mm give you consistent bore size across parts. Featuring a left-hand spiral flute and right-hand cutting, it delivers smooth cutting action and reliable chip evacuation for clean bore surfaces.

Ideal for engineers, technicians, and hobbyists who need reliable bore finishing in a variety of materials. The straight shank clamps securely in common toolholders, supporting quick setup and stable cutting.

• Tight DIN 212-B tolerance you can trust: Delivers a bore size of D = 0 + 0.004 mm, enabling repeatable results and reducing rework across production runs.
• HSS-E (M35 Cob) for long tool life: Cobalt-enriched high-speed steel offers improved wear resistance and durability, helping you cut faster and last longer in demanding materials.
• Left-hand spiral flute with right-hand cutting for efficient cutting: The flute orientation promotes smooth chip flow and reduced clogging, while the cutting direction provides predictable bore geometry and finish.

This reamer is designed to deliver precise, finished bores with fewer passes, improving throughput and part quality. The secure straight shank ensures reliable alignment in standard toolholders, minimizing runout and tool chatter. The combination of M35 cobalt-enhanced HSS-E material and optimized flute geometry provides durable performance, so you can rely on consistent results across jobs and materials. For workshops and production environments that require repeatable bore finishes, this Magafor reamer delivers dependable results you can count on.
