Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 17.90mm

The Toolex Taper Shank Reamer is a long-length HSS reamer (M2) designed for finishing internal holes with high precision.

Its taper shank and BS 328/4 sizing ensure reliable seating in standard machines, while a left-hand spiral flute with right-hand cutting promotes efficient chip removal and a clean, accurate bore. The 17.90 mm diameter is manufactured to ISO H5 (D) tolerance. Manufactured to order; please allow 24–48 hours for despatch.

• Long-length taper shank for extended reach: Enables finishing deep or complex bores with stable guidance, reducing setup changes and improving consistency across parts.
• Left-hand spiral flute with right-hand cutting: Enhances chip evacuation and delivers a smooth, accurate hole finish across a range of materials.
• ISO H5 (D) tolerance on M2 HSS: Ensures tight bore size control and repeatable results, aligned with BS 328/4 taper standards for compatibility with standard tooling and fixtures.

This reamer helps you achieve repeatable, high-precision bore finishes in demanding machining tasks. The tapered shank design provides secure seating and minimal runout in typical machine spindles, while the M2 HSS construction offers reliable performance and long tool life under professional use. Because it is manufactured to order, you can expect a targeted lead time that supports efficient project scheduling.
