Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 12.46mm

Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 12.46mm is an intermediate-precision finishing tool designed to bring drilled holes to a precise diameter with a smooth, burr-free finish. It suits machinists, engineers, and workshop professionals who need reliable hole finishing with minimal post-processing. The straight shank is compatible with standard collets and chucks for quick, repeatable setups.

Featuring a left-hand spiral flute and right-hand cutting, this reamer delivers efficient chip evacuation and stable cutting in a variety of materials. Made from HSS-E (M35 cobalt) for improved wear resistance, it meets DIN 212-B with a tolerance of D = 0 + 0.005 mm, ensuring consistent, high-accuracy holes at 12.46 mm.

• Tight, repeatable size control: DIN 212-B tolerance D = 0 + 0.005 mm provides a very precise final hole diameter, reducing the need for secondary finishing and enabling consistent fits across parts.
• Efficient chip evacuation with spiral flute: Left-hand spiral flutes work with right-hand cutting to carry chips away from the cutting edge, promoting cleaner holes and smoother reaming in through-holes.
• Durable HSS-E (M35 cobalt) construction: The cobalt-infused high-speed steel offers superior wear resistance, extending tool life in tough materials and delivering reliable performance over more jobs between changes.

With its precise tolerances and durable design, this reamer helps you finish holes consistently on the first pass, speeding up setups and reducing rework. The combination of a straight shank, spiral flute geometry, and M35 cobalt steel supports steady performance in daily production, prototyping, and repair work alike.
