Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 7.63mm

Magafor Reamer - Spiral Flute - Straight Shank - HSS-E - 7.63 mm is an intermediate-precision reamer engineered to finish holes to exact size in steel and alloy workpieces. Made from HSS‑E (M35 cobalt), it delivers durable wear resistance and stable sizing, making it a dependable choice for production runs, repairs, and precision assemblies.

Featuring a left-hand spiral flute and right-hand cutting, the tool is optimized for standard forward rotation, yielding clean bore finishes with reliable chip evacuation. The straight shank design offers broad compatibility with common chucks and collets, while the 7.63 mm nominal size and DIN 212-B tolerance of D = 0 + 0.005 mm ensure tight, repeatable results.

• Left-hand spiral flute with right-hand cutting: Efficient chip evacuation and clean bore finishes when used in forward rotation, reducing rework and improving surface quality.
• HSS‑E (M35 cobalt) for extended life: Superior wear resistance and heat tolerance keep size accuracy over many holes and tougher materials.
• DIN 212-B tolerance: D = 0 + 0.005 mm: Delivers a tight, predictable bore size, minimizing finishing steps and ensuring consistent results across parts.

This reamer supports steady, repeatable machining outcomes from setup to finish. With its robust construction, cobalt-enhanced steel, and precise geometry, you gain reliable bore sizing, reduced downtime, and better part quality in production, repair, or prototyping work.
