• BS 328/4 taper shank design: Provides secure seating in compatible holders, reducing runout and ensuring repeatable results during reaming.
• Long-series HSS M2 with left-hand spiral flute: Long length for deep bores and efficient chip evacuation, with cutting action that minimizes rubbing for a smoother bore finish.
• ISO H5 tolerance (D): Delivers tight diameter control for reliable mating with components and consistent hole quality.

With this reamer, you get a stable, repeatable tool that finishes holes accurately in long bores, reducing rework and speeding up production. The taper shank secures the tool in your holder, the long length reaches deep into workpieces, and the HSS M2 construction provides durability for repeated use. The ISO H5 tolerance supports consistent assembly and part interchangeability, helping you maintain high-quality results across jobs.
