Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 27.70 mm

The Toolex Taper Shank Reamer, 27.70 mm diameter, is an intermediate-precision HSS finishing tool designed to deliver accurate, consistent hole sizes in metalworking projects. Its taper shank offers secure mounting in standard tooling, while the long-length flute enables finishing deeper bores. The tool uses a left-hand spiral flute with right-hand cutting, optimizing chip evacuation and cutting action for a clean, repeatable finish.

Made to BS 328/4 and ISO H5 tolerance, this reamer is produced from HSS M2 for durability and long life. It is manufactured to order by Toolex Ltd, with despatch typically 24–48 hours after order. Note: if the listing shows “in stock,” that refers to blanks ready to be machined into the finished reamer.

• Taper shank mounting (BS 328/4): Secure, aligned seating in collets or holders to minimise runout and maintain accuracy during reaming.
• Left-hand spiral flute with right-hand cutting: Enhances chip evacuation and cutting stability for a smoother, more reliable finish in deeper holes.
• Long-length HSS (M2) for deep bores: Extended reach and consistent hole size across the length of engagement, aligned to ISO H5 tolerance.

With secure mounting, efficient chip control, and a long-reach design, this reamer helps you finish holes to spec faster, reduces the need for rework, and supports reliable performance across demanding metalworking tasks.
