Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 21.04mm

The Toolex Taper Shank Reamer – HSS Spiral Flute Long Length (21.04 mm) is an intermediate precision M2 high-speed steel reamer designed to finish drilled holes to exactly 21.04 mm. Its taper shank enables fast, secure seating in compatible equipment, while the long flute length supports controlled material removal in deep or extended holes. The left-hand spiral flute with a right-hand cutting action promotes efficient chip flow and a smooth bore across a range of materials.

Manufactured to BS 328/4 and ISO H5 tolerance, this tool delivers tight size control and repeatable bore results. It is produced to order, with typical despatch within 24–48 hours, making it suitable for production cycles and workshop use where reliability matters.

• Taper Shank Design: Enables fast, secure seating for stable alignment in compatible holders, reducing runout and improving bore accuracy in long or deep holes.
• ISO H5 Tolerance: Provides precise, repeatable hole sizes so assemblies fit first time and rework is minimized.
• Left-Hand Spiral Flute & Right-Hand Cutting: Ensures efficient chip evacuation and a clean bore finish across common workpieces.

In daily use, this Toolex reamer combines robust HSS construction with a long-length, taper-shank design to deliver consistent bore quality, faster setup, and reliable performance in production or workshop settings.
