Toolex Reamer - Taper Shank - Spiral Flute - Standard Length - HSS - H5 - 38.39 mm

Toolex Reamer - Taper Shank - Spiral Flute - Standard Length - HSS - H5 - 38.39 mm is an intermediate precision reamer made from high-speed steel (M2) with a taper shank for secure seating in machine tool spindles. It features a left-hand spiral flute and right-hand cutting, optimized for accurate bore enlargement and smooth chip control.

Manufactured to order by Toolex Ltd., this reamer is sized at 38.39 mm with ISO H5 tolerance (-0 +0.005 mm). Please allow 24/48 hours for despatch. It’s designed for engineers, machinists, and workshops that need consistent, precise bore finishing in drilling and reaming operations.

• Taper shank for secure mounting: Ensures precise alignment in standard toolholders, reducing runout and delivering consistent bore sizes across jobs.
• Left-hand spiral flute with right-hand cutting: Enables efficient material removal and a clean, uniform bore finish with reliable chip control in a range of materials.
• ISO H5 tolerance on 38.39 mm, HSS (M2): Delivers a tight, interchangeable bore size for reliable fits with mating parts while offering long tool life and durability.

Using this reamer improves workflow by delivering precise bore dimensions in a single setup, reducing rework and downtime. The taper shank provides stable performance in standard machine spindles, while the HSS M2 material resists wear and maintains cutting geometry. The ISO H5 tolerance supports repeatable results and easy interchange with other tooling, giving you confidence to plan production around a single reamer.
