Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 21.50mm

The Toolex Taper Shank Reamer is a precision finishing tool designed to produce accurate, smooth deep-hole bores. With a 21.50 mm size and M2 high-speed steel, it maintains tight control across steels and alloys. Its long-length taper shank provides secure seating in standard holders, while BS 328/4 taper compliance and ISO H5 tolerance ensure consistent hole size and repeatable results.

Designed for engineers, machinists, and workshop teams, this reamer enables reliable finishing in demanding applications where hole accuracy and surface finish matter. It is manufactured to order, with dispatch typically within 24–48 hours.

• Long-length taper shank for deep holes: Reaches deeper bores while maintaining alignment and finish accuracy, reducing the need for secondary tools.
• Left-hand spiral flute with right-hand cutting: Enables efficient chip evacuation and stable material removal for a smooth, controlled hole finish.
• HSS M2 with ISO H5 tolerance: Provides durable cutting edges and a precise hole size with secure seating in standard holders; BS 328/4-compliant design for reliable, repeatable results.

Using the Toolex reamer means fewer tool changes and less rework, as you achieve ready-to-use bores in a single finishing pass. The combination of deep reach, stable cutting geometry, and tight dimensional control translates to consistent results, improved throughput, and higher-quality parts across demanding materials and through-bores.
