Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 5.73mm

Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 5.73mm is an intermediate-precision finishing tool designed to bring holes to a precise diameter with a clean, smooth finish. Made from HSS-E (M35 cobalt) and featuring a straight shank, it is built for compatibility with standard drill chucks and collets, making it a reliable choice for machine shops and workshops.

Its design pairs a left-hand spiral flute with right-hand cutting to optimize chip control and cutting action, delivering consistent results in a variety of materials. The reamer is specified to DIN 212-B with a tolerance of D = 0 + 0.004 mm, ensuring a tight, repeatable final bore size.

• Left-hand spiral flute for efficient chip evacuation: Chips are directed away from the cutting edge, reducing clogging and heat buildup to maintain a smooth bore finish.
• HSS-E (M35 cobalt) for extended tool life: Cobalt-enhanced steel increases wear resistance, delivering longer tool life in demanding materials and finishing work.
• DIN 212-B tolerance (D = 0 + 0.004 mm): Provides a precise final diameter, reducing the need for secondary finishing and ensuring repeatable bore quality.

With this reamer, you can achieve reliable bore finishes quickly, improving consistency across parts and saving time on deburring or rework. The combination of durable HSS-E material, a clear spiral-flute design, and tight DIN tolerance delivers predictable performance in production and prototyping, making it a dependable addition to any machining toolkit.
