The machine reamer in HSSE with a 6-degree left-hand helix, shape "B", manufactured in accordance with DIN 208 and UNI 6854 standards, is a precision tool designed for high-performance machining operations. It is the ideal solution for reaming operations on ferrous materials, carbon steels, alloy steels, stainless steel, cast iron, and light alloys such as aluminum and brass. The HSSE (high-speed steel with cobalt) body ensures excellent thermal and mechanical resistance, providing superior durability even under demanding working conditions.

The special geometry with a 6° left-hand spiral is designed to efficiently evacuate chips away from the hole, improving work area cleanliness and minimizing the risk of jamming—particularly in blind or deep hole applications. The "B" shape, as defined by DIN 208, refers to a reamer with a tapered shank (Morse taper), available in sizes CM1, CM2, CM3, and CM4, ensuring a stable and secure fit with most conventional and CNC machine tools.

One of the distinguishing features of this tool is the ability to customize the reamer diameter with hundredth-millimeter progression, enabling extremely precise operations based on specific customer requirements. The manufacturing tolerance of 0 / +0.004 mm guarantees consistent dimensional characteristics and perfect fits—critical in precision engineering, automotive manufacturing, and mold-making industries.

Thanks to the combination of high-quality materials, certified construction standards, and customizable features, this reamer is the ideal choice for those seeking reliability, long service life, and high accuracy in hole finishing operations.
