With the International Tools 12.400 eco hss twist drill bit, you drill powerful and accurate 30 mm holes in steel and metal. Thanks to the MK3 Morse taper shank, you mount the drill bit directly into your drill press or lathe without any slippage. The roll-forged hss steel absorbs heavy vibrations and minimizes the risk of tool breakage during demanding operations. Built to the din 345 standard with a 175 mm flute length and an overall length of 296 mm, it delivers clean, deep bores with maximum control and stability.
