HSS Parallel Hand Reamers – BS328
- HSS parallel hand reamers, manufactured according to the British Standard (BS) 328, are hand-operated cutting tools designed to produce precise, smooth, and accurately sized holes.
- Features a parallel shank (for holding in chucks or tap wrenches) with parallel cutting edges and a taper and bevel lead at the tip for easier starting. Flutes can be either straight or helical depending on the application.
- HSS parallel hand reamers are used for achieving precise dimensions in engine cylinder bores, fine-tuning holes for bearings and bushings, ensuring accurate alignment of mechanical parts, improving the surface finish of drilled holes, and creating smooth and accurately sized holes in firearm barrels.
