Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 11.45 mm is an intermediate precision finishing tool designed to bring drilled holes to a precise, smooth final diameter. Built for engineers, machinists, and hobbyists alike, it combines a straight shank for easy integration with common chucks and collets with a left-hand spiral flute and right-hand cutting for controlled material removal and clean hole finishes. The HSS-E substrate (M35 cobalt content) enhances wear resistance, extending tool life in demanding materials. Left-hand spiral flute with right-hand cutting: enables efficient chip evacuation and stable, predictable hole finishing with smooth surface quality. Straight shank for secure, versatile mounting: compatible with standard chucks and collets, reducing runout and simplifying setup in busy machining environments. DIN 212-B tolerance: D = 0 + 0.005 mm: delivers a consistent hole size across parts, supporting reliable fits and tight assembly tolerances. This reamer is ideal for finishing holes to tight, repeatable dimensions in a variety of steels and alloys. Its precise diameter control helps you reduce finishing steps, improve assembly reliability, and achieve professional-quality results with every pass.
