Dormer A125 Extra Length HSS Drill Bit 5.00mm x 200mm

The Dormer A125 HSS Extra Length Drill is designed for long-reach, deep-hole drilling in steel and other hard metals. It can drill holes up to ten times its diameter, making it suitable for applications requiring extended reach. The drill features a 5 mm shank and a total length of 200 mm with a cutting length of 150 mm, and it uses high-speed steel (HSS) material with a vapor ring to enhance performance. The 118° cutting edge is standard and the drill adheres to BS 328 specifications. Its extended length and robust construction enable deeper holes or greater reach in a range of drilling setups, including machines or hand-held applications that can accommodate HSS bits. The tool is compatible with standard drill chucks that accept a 5 mm shank and is intended for use in steel and other hard metals, with guidance on proper installation and operation to achieve effective results.
