Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 31.37 mm

Toolex Taper Shank Reamer, 31.37 mm diameter, is an intermediate precision HSS (M2) long-length reamer designed for finishing holes with high accuracy. The taper shank fits standard toolholders (BS 328/4), and the long length enables deeper bores without sacrificing rigidity.

With a left-hand spiral flute and right-hand cutting, it delivers controlled material removal and consistent bore surfaces across a range of materials. This item is manufactured to order, with a 24/48 hour despatch window to fit production schedules, and aligns to ISO H5 tolerance for precise hole sizes.

• Taper Shank BS 328/4 for quick, secure seating: Quick, secure seating in standard toolholders, reducing setup time and runout.
• Long-length HSS M2 design: Extended reach for deep bores while preserving rigidity and maintaining consistent hole size.
• Left-hand spiral flute with right-hand cutting: Efficient chip evacuation and stable cutting for a smooth bore finish.

This reamer helps you achieve precise, repeatable bores with fewer adjustments or rework. The ISO H5 tolerance ensures consistent hole sizes so parts fit first time, while the HSS M2 construction stands up to repeated use in metalworking. The long length and taper shank streamline setup on machining centers and lathes, improving workflow and reducing downtime. Because it is made to order, you can expect delivery within 24–48 hours after ordering, helping you keep production on schedule.
