Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 8.49mm

The Magafor Reamer is an intermediate-precision HSS-E straight-shank reamer designed to finish holes to exact size. With an 8.49 mm nominal diameter, it’s ideal for shops, technicians, and hobbyists who need reliable, accurate bore finishes in a variety of materials. This tool helps you move from drilled holes to precisely sized bores in fewer steps, improving part fit and consistency.

Its left-hand spiral flute and right-hand cutting work together to deliver stable cutting, efficient chip evacuation, and predictable finishes. This combination minimizes chatter and reduces the need for rework, so you can rely on repeatable results across multiple parts.

• DIN 212-B tolerance for repeatable size: Tolerance of D = 0 + 0.005 mm ensures bore sizes stay within tight, consistent limits, which reduces assembly issues and rework.
• Left-hand spiral flute with right-hand cutting: Optimizes chip flow and cutting stability for smooth, clean bore finishes and reduced tool chatter.
• HSS-E (M35 cobalt) with straight shank: Combines wear resistance and durability with versatile machine compatibility, helping the reamer last longer in demanding materials.

Used correctly, this reamer enhances workflow by delivering precise bore diameters in fewer passes, improving part interchangeability and downstream assembly quality. It provides dependable performance for everyday manufacturing, maintenance, and DIY projects alike, giving you confidence in every bore you finish.
