Product Description
Dormer B9031.5 is a precision-engineered high speed steel straight flute square hand reamer with a 20 mm diameter, 1.4 mm shank and 57 mm overall length. Designed for industrial use, this tool delivers consistent and accurate hole finishing across a wide range of applications in manufacturing, metalworking, laboratory maintenance and assembly processes. The straight flute offers controlled material removal, making it especially suitable for opening out parallel holes and finishing pre-formed tapered holes with a smooth, true surface.
The hand reamer is constructed from high speed steel, granting excellent hardness, wear resistance and longevity. Its square shank is optimized for manual operation and provides reliability against slippage or motion distortion during rotary tasks.
With standards compliance to BS 328, DIN 9 A and ISO3465, the Dormer B9031.5 hand reamer guarantees quality, dimensional accuracy and compatibility with international industrial protocols. The 57 mm length makes it adept for environments with limited access, such as maintenance workshops, machine assembly stations, and laboratory settings.
This tool is suitable for both ferrous and non-ferrous materials, including steels, aluminum and copper alloys. Metric reamers, like the B9031.5, feature a 1-in-50 taper for progressive diameter control, enhancing fitment and part integration. Its precise taper pin design ensures effective finishing of pre-formed holes and the creation of true geometries for pins, bolts and fasteners.
Dormer's origin in Germany assures users of advanced manufacturing processes, stringent quality assurance and robust performance. Whether used in construction, automotive repairs, machine installations, or maintenance, this hand reamer provides professional results and reliability.
