AYCDHDAOSolid Carbide Through-Coolant Drill DAOSold0pcsDHF Solid Carbide Through-Coolant Drill DAO, the carbide counterpart of an HSS jobber drill, produces holes and, with its straight milling shank, mounts directly in a mill or machining-centre holder. Sister series include DBO (sizes 3~20mm), DCO (sizes 4~12mm), DAVO (rated to HRC45). What sets this one apart is an ultra-fine MG0.6 substrate with a G10 coating, rated to HRC52. It covers diameter 3~20mm, flute length 20~79mm, overall length 62~131mm, depth-to-diameter 3~7D, 2 flutes, in 107 sizes, made in Taiwan. It machines carbon and alloy steel, cast iron. What is the smallest diameter? 3mm. How deep can it drill? 3~7D. Can it drill hardened steel? Not recommended; choose a high-hardness series instead. Typical uses: continuous deep-hole drilling, precision drilling in production parts, pilot holes before tapping.
