Dormer HSS Long Series Drill Pack Of 10

The Dormer A110 Metric Long Series Drill Bits are versatile long-reach drills designed for drilling deep holes in a range of materials. They can be used by hand or on machines, providing extended reach and precise drilling. Key characteristics include a tip diameter of 4.0 mm, a working length of 78 mm, and an overall length of 119 mm, with a maximum 118° point. The drills are designed for deep hole drilling, up to 6 times the diameter, and are made from High-Speed Steel (HSS). They conform to DIN 340RN, BS 328, and ISO 494 standards and are compatible with standard drill chucks and drill presses for use in steel, cast iron, and other materials. The product features an 118-degree conventional point, which aids re-grinding, and a steam oxide finish that reduces built-up edge and improves lubricity. An increased length enables deeper holes or greater reach, suitable for both machine and hand-held drilling tasks.
