This 7 piece HSS machine reamer set comes in a wooden box with foam insert for convenient and safe storage. All reamers from this set are subject to tolerance class H7. These machine reamers have a short guide part compared to hand reamers, as the guide is carried out by the machine spindle itself. In addition, the machine reamers have a short cut compared to hand reamers, making them particularly suitable for rubbing blind hole holes.
