Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 7.39mm

Magafor Reamer, Spiral Flute, Straight Shank, HSS-E (M35 Cob) with a 7.39 mm diameter is an intermediate precision finishing tool designed to bring drilled holes to an exact size. Crafted from HSS-E and offered with a straight shank, it pairs with standard chucks and collets for dependable performance in metalworking projects—from production runs to workshop tasks. The left-hand spiral flute and right-hand cutting direction optimize chip evacuation and cutting stability, helping you achieve clean, accurately sized holes.

It is manufactured to DIN 212-B with a tolerance of D = 0 + 0.005 mm, delivering consistent hole size across runs.

• DIN 212-B tolerance for precise hole size: With a tolerance of D = 0 + 0.005 mm, holes finish to the intended diameter with minimal variation, reducing rework and ensuring dependable fit in assemblies.
• HSS-E (M35 Cob) for longer tool life: The cobalt-enriched substrate provides enhanced wear resistance, helping the reamer last longer in demanding materials and production runs.
• Left-hand spiral flute with right-hand cutting for efficient chip evacuation: This geometry promotes stable cutting and smoother hole finishes by guiding chips away from the cutting edge as you work.

This reamer delivers repeatable, accurate hole finishing with straightforward setup for consistent results. By combining precise sizing, durable construction, and reliable toolholding compatibility, it supports faster workflows, fewer interruptions, and improved overall part quality for engineers, machinists, and hobbyists alike.
