Drill bits
I use the Dewalt pilot point,
14 Pc. PILOT POINT® Drill Bit Set - DW1169 | DEWALT
, and cutting oil for steel and aluminum. Forstner,
Rockler High-Carbon Steel Forstner Bits, Imperial Sizes, ¼” to 2-1/8” Diameters (3/8” Shank)
, for wood and hammer drill for concrete. Never cheap out on tools.
