AYCDHDBOSolid Carbide Through-Coolant Drill DBOSold0pcsDHF Solid Carbide Through-Coolant Drill DBO, 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 DAO (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 28~101mm, overall length 66~153mm, depth-to-diameter 5~10D, 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? 5~10D. 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.
