Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 25.85 mm

The Toolex Taper Shank Reamer is an intermediate-precision HSS long-series tool designed to finish tapered holes with excellent control. With a taper shank for secure seating in toolholders and a nominal diameter of 25.85 mm, it’s ideal for engineers, machinists, and workshops needing consistent, deep bore finishes.

Made from M2 high-speed steel, this reamer uses a left-hand spiral flute and right-hand cutting for stable, predictable cutting action. It conforms to BS 328/4 and ISO H5 tolerance. Each reamer is manufactured to order, with despatch typically within 24–48 hours.

• Long-length taper shank for deep, accurate bore finishing: Allows secure seating in toolholders and enables finishing deep bores with minimal runout, improving concentricity and wall quality.
• Left-hand spiral flute with right-hand cutting: Provides efficient chip evacuation and stable cutting, reducing wander and delivering cleaner bore walls.
• ISO H5 tolerance on BS 328/4 specification: Delivers tight dimensional control for reliable fits with precision components and consistent results across jobs.

In daily use, this reamer helps you achieve consistently sized tapered holes with smooth surfaces, speeding up setups and reducing downtime. The 25.85 mm diameter and long reach let you tackle deep holes in thicker workpieces without frequent tool changes, while the M2 HSS core stands up to repeated use in a range of metals. Manufactured to order, it arrives ready for immediate use with your collet or chuck and delivers repeatable, high-quality bore finishes across demanding applications.
