Toolex Reamer - Taper Shank - Spiral Flute - Standard Length - HSS - H5 - 10.89 mm

Finish drilled holes to ISO H5 tolerance with the Toolex Reamer—a taper-shank, spiral-flute reamer designed for intermediate precision. Crafted from high-speed steel (M2), it uses a left-hand spiral flute and right-hand cutting to deliver predictable, smooth material removal. The 10.89 mm nominal diameter is held to ISO H5 (-0 to +0.005 mm), making it suitable for a range of steels and alloys.

Manufactured to order with a 24/48 hour dispatch window to match your project timelines.

• ISO H5 bore tolerance and precise diameter: The 10.89 mm nominal size is held to ISO H5 (-0 to +0.005 mm) for consistent fits and reduced rework across common steels and alloys.
• Left-hand spiral flute with right-hand cutting: Optimizes chip control and cutting stability for clean, predictable reaming results.
• Taper shank and standard length for secure seating: Ensures reliable tool seating in compatible machines and a predictable reach for typical reaming tasks.

With this setup, you gain dependable bore finishes, fewer deviations, and smoother workflow—helping you complete drilling and finishing tasks faster with consistent results. The taper shank provides secure seating and easy changeovers in your machine, while the M2 high-speed steel offers wear resistance for longer life in demanding applications.
