Toolex Reamer - Taper Shank - Spiral Flute - Standard Length - HSS - H5 - 21.51 mm

The Toolex Reamer - Taper Shank - Spiral Flute - Standard Length is an intermediate precision reamer crafted from M2 HSS (high-speed steel) for finishing holes with tight control. Sized for a 21.51 mm diameter, it combines a taper shank with left-hand spiral flutes and right-hand cutting to deliver stable, clean hole finishes on a variety of materials. It’s built to ISO H5 tolerance (D = -0 to +0.005 mm) and aligns with BS 328/4 standards, providing reliable, repeatable results in production or workshop settings.

• ISO H5 tolerance for precise holes: Keeps hole diameters within tight limits (-0 to +0.005 mm) to minimize finishing time and ensure consistent accuracy.
• Left-hand spiral flute with right-hand cutting: Optimizes cutting action and chip evacuation for smooth, controlled reaming and uniform surface finish.
• Taper shank in standard length: Offers secure mounting on compatible holders for rigid, repeatable performance across multiple setups.

Manufactured to order by Toolex Ltd, this reamer typically despatches within 24–48 hours. The combination of M2 HSS durability, precise ISO tolerance, and proven BS 328/4 compatibility makes it a reliable choice for engineers, machinists, and workshop professionals who demand consistent hole quality with minimal rework.
