Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 1.86mm

Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 1.86mm is an intermediate-precision reamer designed to finish pre-drilled holes to a precise diameter. It uses HSS-E (M35 cobalt) with a straight shank and features a left-hand spiral flute paired with right-hand cutting for clean, consistent bore finishes and straightforward setup.

• DIN 212-B precision tolerance: D = 0 + 0.003 mm ensures consistent hole diameter across parts, supporting reliable fits and repeatable results.
• Left-hand spiral flute with right-hand cutting: Optimizes chip evacuation and delivers smooth bore finishes with stable cutting performance.
• HSS-E (M35 cobalt) steel: Delivers enhanced wear resistance and longer tool life for demanding applications and tougher materials.

With this reamer in your toolkit, you gain a reliable, repeatable path to precise holes, reducing scrap and rework while speeding up setup. The straight shank ensures easy integration with standard chucks and holders, and the cobalt-enhanced HSS-E material resists wear to extend service life. Together with the optimized flute geometry, you’ll achieve clean surfaces and consistent bore quality, helping your project meet tight tolerances and finish requirements more efficiently.
