Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 4.94mm

Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 4.94mm is an intermediate precision reamer designed to finish drilled holes to tight, repeatable tolerances. With a left-hand spiral flute and right-hand cutting, it promotes smooth chip flow and stable bore quality. The straight shank fits standard toolholders, while the DIN 212-B tolerance of D = 0 + 0.004 mm ensures consistent hole sizes across production runs.

• DIN 212-B tolerance: D = 0 + 0.004 mm: Ensures hole diameters stay consistent across parts and batches, reducing rework and improving fit.
• HSS-E (M35 cobalt) construction: Delivers higher wear resistance and longer tool life in challenging materials, helping you finish more holes per tool.
• Left-hand spiral flute with straight shank: Provides controlled chip evacuation and stable alignment in typical reaming setups, compatible with standard holders.

When you pair this reamer with your drilling and finishing process, you gain predictable bore sizes, cleaner hole finishes, and fewer quality issues. The cobalt-enhanced HSS material stands up to tougher workpieces, while the straight shank and flute geometry support quick setup and reliable guidance through the hole. For production runs or precise prototypes alike, this reamer helps you achieve precise, repeatable results with less downtime between parts.
