Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 5.65mm

Magafor Reamer, 5.65 mm, is an intermediate-precision HSS-E straight shank reamer built for finishing drilled holes with tight size control. Made from cobalt-rich HSS-E (M35), it uses a left-hand spiral flute and right-hand cutting to produce smooth, accurate holes with a DIN 212‑B tolerance of D = 0 + 0.004 mm.

• Tight, DIN 212-B precision tolerance: D = 0 + 0.004 mm ensures consistent hole size across parts, reducing the need for post-processing and improving fit quality.
• HSS-E cobalt alloy for long tool life: M35 cobalt content provides enhanced wear resistance and heat tolerance, helping maintain a sharp cutting edge through repeated reaming in steel and harder alloys.
• Left-hand spiral flute with straight shank for stable, efficient use: The left-hand flute aids chip evacuation while the straight shank offers stable clamping and alignment in standard chucks for reliable reaming performance.

This reamer supports efficient, repeatable hole finishing in everyday machining workflows, helping you reduce chatter, minimize rework, and achieve consistent results across batches. Its durable construction and precise tolerance empower you to trust the size and finish of every hole you produce, improving overall workflow and finished-part quality.
