Ginsco 3pcs HSS Step Bits Set

Ginsco 3pcs 4-12/20/32mm Large HSS Steel Step Drill Bit Set Hole Cutter

Great for using with plain steel, plastic, plywood and PVC. They are very sharp and cut smooth.

Standard high-quality HSS bits are good for 99% of the drilling tasks that anyone would do. IMO the best solution for a home shop is to buy HSS, and use a spotting drill.

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.
