For metal drilling with a DEWALT extra long bit like the DW1608, match the bit diameter to your fastener size and ensure the material thickness is less than the flute length. Use cutting oil to reduce heat and extend bit life. The 135° split point on this HSS bit helps prevent walking on curved surfaces, improving accuracy in steel or aluminum.
