Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 7.81mm

The Magafor Reamer (7.81 mm) is an intermediate-precision finishing tool designed to produce clean, accurately sized holes. With a straight shank and HSS-E (M35 cobalt) composition, it delivers reliable, repeatable performance for engineers, machinists, hobbyists, and workshop technicians. Its left-hand spiral flute and right-hand cutting optimize cutting action and chip flow for consistent results.

This reamer is built to tight specifications, featuring DIN 212-B tolerance of D = 0 + 0.005 mm to ensure finished holes meet exact size requirements. The combination of high-speed steel with cobalt enhances wear resistance, enabling longer tool life even in demanding materials and higher-speed applications.

• Tight DIN 212‑B tolerance: D = 0 + 0.005 mm ensures consistent hole size and minimizes rework, helping you hit exact specifications every time.
• HSS‑E with M35 cobalt for durability: Enhanced hardness and heat resistance extend tool life and maintain cutting performance in tougher materials.
• Straight shank with left‑hand spiral flute: Secure mounting in standard tool holders and efficient chip evacuation support smooth, reliable cuts and repeatable finishes.

Used across machining, drilling, and finishing workflows, this reamer helps you reduce downtime, improve hole quality, and maintain throughput. The robust design and precise geometry deliver dependable results from the first pass to the final finish, making it a trusted choice for both professional shops and serious hobbyists.
