Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 12.27mm

Magafor Reamer - Spiral Flute - Straight Shank - HSS-E (M35 Cob) is an intermediate-precision reaming tool designed to bring drilled holes to a precise, repeatable size. Its straight shank and left-hand spiral flute pair with a right-hand cutting edge to deliver smooth bore finishes, even in tougher metals. For a 12.27 mm nominal bore, it meets the DIN 212-B tolerance of D = 0 + 0.005 mm, helping you achieve tight control over hole dimensions in production runs.

• DIN 212-B tight tolerance: Delivers repeatable hole sizes with a precise D = 0 + 0.005 mm specification, reducing the need for subsequent rework.
• HSS-E (M35 cobalt) durability: Higher red hardness and wear resistance extend tool life and maintain cutting performance across materials.
• Left-hand flute with right-hand cutting: Optimizes chip evacuation and provides stable cutting action for cleaner finishes and consistent bore quality.

Using this reamer helps you achieve cleaner, more accurate holes in fewer passes, reducing downtime and improving overall workflow. Its robust construction and precise tolerances give you confidence in both batch production and maintenance tasks, making it a dependable choice for machinists, engineers, and workshop teams.
