Drill 20.5 mm holes in metal and structural steel with confidence using the International Tools eco hss twist drill din 345. Featuring an MK2 Morse taper shank, it mounts directly into the spindle of your drill press, radial arm drill, or lathe tailstock without a standard chuck. This direct fit eliminates slipping under load and minimizes vibrations for true running accuracy. The roll-forged hss construction provides excellent toughness and resistance to breakage during heavy workshop tasks. With a 145 mm flute length, two cutting edges, and an overall length of 243 mm, this drill bit clears chips efficiently to keep your metalworking projects running smoothly.
