Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 7.77mm

The Magafor Reamer with Spiral Flute and Straight Shank is an intermediate-precision HSS-E reamer designed to finish holes to a precise 7.77 mm diameter. Its straight shank accepts standard toolholders, while the left-hand spiral flute paired with right-hand cutting provides stable, controlled material removal for clean bore finishes. This reamer is well suited for machine shops, engineers, tradespeople, and hobbyists who require reliable hole accuracy with minimal post-processing.

Built from HSS-E (M35 cobalt) for enhanced wear resistance and heat tolerance, this reamer delivers longer tool life in challenging materials and busy production environments. The DIN 212-B tolerance of D = 0 + 0.005 mm ensures a tight, predictable finished size, helping reduce rework and deliver consistent results across jobs.

• Left-hand spiral flute with right-hand cutting: Efficient chip evacuation and stable cutting produce clean, reproducible holes across a range of metals.
• Durable HSS-E (M35 cobalt) alloy: Superior wear resistance and heat tolerance extend tool life in demanding materials and high-speed applications.
• DIN 212-B tolerance: D = 0 + 0.005 mm: Tight, predictable hole size minimizes finishing steps and improves production yield.

This reamer helps you achieve consistent bore quality, reduces rework, and supports smoother workflows from setup to finished part—making it a dependable choice for precision finishing in metalworking projects.
