Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 5.45mm

Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 5.45mm is a precision finishing tool designed for machinists, engineers, and hobbyists who need clean, accurate through-holes. Built on high-speed steel with cobalt (HSS-E), this straight-shank reamer delivers dependable performance across a range of materials while fitting standard holders and chucks.

Featuring a left-hand spiral flute and right-hand cutting action, it excels in controlled metal removal and consistent hole quality. The DIN 212-B tolerance of D = 0 + 0.004 mm helps you achieve precise final dimensions with repeatable results.

• Left-hand spiral flute for efficient chip evacuation: The left-hand helix design helps move chips away from the cutting edge, reducing clogging and heat buildup for smoother, more predictable finishing in through-holes.
• Straight shank for reliable grip and compatibility: A rigid, straight shank works with standard tool holders and collets, minimizing runout and ensuring consistent hole alignment across setups.
• Durable HSS-E (M35 cobalt) construction with tight DIN 212-B tolerance: The high-hardness cobalt-containing steel resists wear in demanding materials, while the tight tolerance D = 0 + 0.004 mm keeps hole sizes within spec for reliable assembly and performance.

This reamer is designed to improve your workflow by delivering precise hole finishes in fewer passes, reducing downtime and rework. With reliable performance across common engineering materials, it supports consistent results in every project—from prototype work to production runs.
