Dormer A110 HSS Long Series Drill 1/8in OL106mm WL69mm DORLS18

High-speed steel (HSS) Dormer A110 Imperial Long Series Drill Bits are designed for general-purpose use with a long reach to drill deep holes in a variety of metals. Suitable for both hand and machine drilling, these bits are built for long reach and precision. Key specifications include a tip diameter of 1/8 inch (3.18 mm), an overall length of 106 mm, and a working length of 69 mm. The cylindrical shank and HSS material deliver the necessary durability for drilling steel, cast iron, and other metals. The 118° point angle supports easy re-grinding, and a steam oxide finish helps reduce built-up edge and improve lubricity. The depth of drilling can reach up to six times the diameter, enabling deeper holes or increased reach, while compatibility with standard drill chucks and drill presses ensures broad applicability in both hand and machine setups. This product is manufactured to DIN 340 standards and is suitable for metal drilling applications requiring reliable long-reach performance.
