Toolex Reamer - Taper Shank - Spiral Flute - Standard Length - HSS - H5 - 16.90 mm

The Toolex Reamer is a 16.90 mm taper-shank finishing tool made from high-speed steel (M2). Its left-hand spiral flute and right-hand cutting deliver clean, accurate holes with a reliable finish, suitable for a range of materials and machining setups. It is manufactured to BS 328/4 standards and to ISO H5 tolerance (D = ISO H5 (-0 +.005 mm)).

This standard-length reamer uses a taper shank for secure mounting in standard chucks and collets, helping reduce runout and improve hole consistency. Supplied by Toolex Ltd, the tool is manufactured to order with dispatch typically within 24–48 hours.

• Left-hand spiral flute with right-hand cutting: Optimizes chip control and finishing action for a smooth, dimensionally reliable hole in a variety of materials.
• Taper shank for secure mounting: Ensures rigid seating in standard holders, reducing runout and delivering consistent hole size during production runs.
• ISO H5 tolerance on HSS (M2): Maintains tight diameter control (-0 +.005 mm) for repeatable fits and dependable assembly outcomes.

Using this reamer helps you achieve precise, repeatable hole sizes with strong surface finish, which reduces rework and speeds up workflows. The combination of a taper shank, high-quality M2 HSS material, and strict ISO H5 tolerance supports reliable performance across both prototyping and production environments.
