Drill Hog Step Drill Bit 1/4″-1-3/8″ Molybdenum M7 Lifetime Warranty USA
The Drill Hog cuts more aggressive because of the dual flutes. I use only molybdenum or solid carbide to drill stainless, very hard alloys or hardened steel.
For aluminum or anything less hard than steel, plain HSS actually is superior because it takes an extremely sharp edge and is easy to sharpen by hand.
