Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 3.12mm

Magafor Reamer — Spiral Flute, Straight Shank, HSS-E (M35 cobalt) with a 3.12 mm diameter — is designed for finishing holes to precise dimensions in metalworking. The left-hand spiral flute paired with right-hand cutting delivers consistent material removal for smooth bore finishes, making it suitable for both production runs and workshop projects. The DIN 212-B tolerance of D = 0 + 0.003 mm ensures holes stay tight and repeatable.

This straight-shank reamer is ideal for engineers, machinists, and hobbyists who need reliable hole finishing in steel, alloys, and other common metals. The HSS-E substrate provides enhanced wear resistance and edge retention, helping you achieve repeatable results even when working with tougher materials.

• Left-hand spiral flute with right-hand cutting: Promotes stable cutting action and efficient chip evacuation, helping produce consistent bore sizes and smoother finishes.
• HSS-E (M35 cobalt) construction: Delivers improved wear resistance and longer tool life under demanding cutting conditions.
• DIN 212-B tolerance (D = 0 + 0.003 mm) and 3.12 mm diameter: Ensures tight, repeatable hole sizes for reliable fits and reduced rework.

Used correctly, this reamer can streamline finishing operations, improve part consistency, and reduce downtime by delivering reliable, accurate holes in a range of common metals.
