What it is
The DeWalt DT5557-QZ is a metal drill bit with a diameter of 10 mm, available in a multipack of 10 pieces. With a working length of 84 mm and a total length of 133 mm, it is designed for deep, precise drilling of thick metal components, a size in great demand in structural work.
A metal drill bit is an HSS, cobalt or coated twist drill for drilling steel, cast iron, non-ferrous metals and plastic with a drill or drill driver.
What it is for
Used for drilling steel, stainless steel and aluminium, on a pillar drill or with a hand-held drill and in workshop machining of steel, aluminium and alloy parts.
How to use it
Mark the centre with a centre punch, clamp the workpiece and drill at a speed that is lower the larger the diameter and the harder the material. Maintain steady pressure, lubricate with cutting oil on steel and stainless steel and, for large diameters, drill a pilot hole first. Withdraw the bit frequently to clear the swarf, and never touch the swarf with bare hands.
