Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 11.93mm

Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 11.93mm is a precision finishing tool designed to bring holes to a tight, repeatable diameter. Made from high-speed steel (M2) with a taper shank for secure mounting in BS 328/4 tool systems, and ISO H5 tolerance for consistent bore size. The left-hand spiral flute and right-hand cutting sequence promote efficient chip control and a smooth bore finish, even in deeper holes.

• ISO H5 tolerance on a BS 328/4 taper shank: Delivers precise bore size and a secure fit in standard tool holders, reducing rework and setup time.
• Left-hand spiral flute with right-hand cutting: Optimizes chip flow and cutting stability for cleaner, more accurate holes in longer bores.
• Long flute design for deeper bores: Improves chip clearance and rigidity in deep holes, helping maintain hole quality and extend reamer life between sharpenings.

Using this reamer helps you achieve consistent bore sizes, smooth finishes, and reliable results across parts. The HSS M2 construction offers durable wear resistance, while the taper shank provides a secure, repeatable fit in standard tooling, so setup is straightforward and downtime is minimized. The long flute and tailored geometry support efficient chip evacuation in deep holes, making it suitable for production runs and precision work alike. Manufactured to order by Toolex Ltd, this reamer is built to your selected specification with a typical dispatch window of 24–48 hours.
