Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 3.74mm

Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 3.74mm is an intermediate-precision reaming tool designed to finish drilled holes to a precise diameter with a smooth bore. Made from HSS-E (M35 cobalt steel), it delivers reliable wear resistance for demanding metals. It features a left-hand spiral flute with right-hand cutting to optimize chip evacuation and cutting action for accurate bores.

DIN 212-B tolerance: D = 0 + 0.003 mm ensures repeatable hole sizes across passes. The straight shank enables stable clamping in common toolholders, making setup straightforward in both manual and CNC workflows.

• DIN 212-B precision tolerance: D = 0 + 0.003 mm ensures repeatable hole sizes and tighter control across reaming operations.
• Left-hand spiral flute with right-hand cutting: Optimizes chip clearance and cutting action for cleaner bores and reduced heat buildup during reaming.
• HSS-E (M35 cobalt) for durability: Delivers high wear resistance and long tool life, maintaining accuracy in steel and alloy workpieces.

This reamer helps you achieve consistent hole diameters quickly, reducing deburring and rework. The combination of durable HSS-E material, efficient cutting geometry, and a stable straight shank supports reliable performance across production runs and workshop tasks, making it a dependable choice for engineers, machinists, and serious hobbyists tackling precision bore finishing.
