Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 4.61mm

The Magafor Reamer is an intermediate precision HSS-E reamer with a straight shank, crafted to finish holes to exact, reliable diameters. Made from M35 cobalt-containing HSS-E, it delivers durable edge life for demanding materials and everyday workshop use.

With a 4.61 mm nominal diameter and DIN 212-B tolerance of D = 0 to +0.004 mm, this reamer provides consistent hole sizing and a smooth bore finish. Its left-hand spiral flute and right-hand cutting are designed to optimize chip evacuation and cutting action, making it suitable for engineers, machinists, and serious hobbyists working with steel, cast iron, and alloy components.

• Left-hand spiral flute with right-hand cutting: Optimizes chip removal and cutting stability to deliver a uniform hole size and a smooth surface finish in fewer passes.
• HSS-E construction (M35 cobalt): Enhanced wear resistance and longer tool life for demanding materials, reducing downtime and replacement costs.
• DIN 212-B tolerance, D = 0 to +0.004 mm: Tight dimensional control that ensures repeatable results and reliable fits in precision assemblies, minimizing rework.

This reamer supports efficient, repeatable bore finishing from setup to final inspection. The combination of durable HSS-E material, precise tolerance, and optimized flute geometry helps you achieve high-quality bore finishes, improve workflow consistency, and reduce production delays—making it a dependable choice for both professional shops and skilled hobbyists.
