Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 3.77mm

The Magafor Reamer is an intermediate precision finishing tool designed for metalworking professionals, machinists, and serious hobbyists who need reliable, accurately sized holes. With a 3.77 mm diameter and constructed from HSS-E (M35 Cob), this straight shank reamer combines durability with consistent performance for repeated use. Its left-hand spiral flute and right-hand cutting geometry are optimized for controlled chip evacuation and smooth hole finishes, backed by DIN 212-B tolerance of D = 0 + 0.004 mm.

• Tight, repeatable hole size: DIN 212-B tolerance D = 0 + 0.004 mm ensures predictable hole diameters across finishing passes, reducing rework and measurement adjustments.
• Durable HSS-E construction: M35 cobalt-enhanced steel provides excellent wear resistance and edge retention for longer tool life in a range of materials.
• Left-hand spiral flute with straight shank: easy integration in standard holders and efficient chip evacuation support clean, consistent hole finishes with minimal setup hassle.

This reamer helps you finish holes precisely in fewer passes, boosting workflow efficiency and reducing downtime. Its robust materials and precise tolerance inspire confidence for everyday machining tasks—from setup on a CNC mill or lathe to use in manual drilling operations—delivering reliable results you can trust project after project.
