Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 4.45mm

The Magafor Reamer is an intermediate precision HSS-E (M35 cobalt) reamer with a straight shank, designed to finish drilled holes to tight, repeatable tolerances. With a diameter of 4.45 mm, it’s ideal for professionals and hobbyists who need reliable bore finishing in metalworking.

Featuring a left-hand spiral flute with right-hand cutting, it provides efficient chip control and a smooth bore finish. The DIN 212-B tolerance of D = 0 + 0.004 mm ensures repeatable results across jobs, helping parts assemble with confidence.

• Precise bore size at 4.45 mm: Achieves a consistent hole diameter thanks to DIN 212-B tolerance of D = 0 + 0.004 mm, helping assemblies fit reliably and reducing rework.
• Durable HSS-E (M35 cobalt) construction: The cobalt-enhanced steel resists wear and keeps its edge longer in demanding materials, lowering tool changes and downtime.
• Left-hand spiral flute with right-hand cutting: Optimizes chip formation and evacuation, delivering a stable cutting action and a smoother bore finish.

This reamer helps streamline finishing operations by delivering consistent bore dimensions with fewer passes, compatible with standard toolholding thanks to the straight shank. Its robust material and precise tolerance reduce rework and extend tool life, making it a dependable choice for machinists, engineers, and workshop teams seeking reliable, repeatable results.
