Need help drilling stainless steel sink.
What is the best drill bits available on amazon for stainless steel? My local hardware store have low quality drills bits.
The sink is made by LQS and its 16 gauge stainless steel about 1/8 thick. Ive tried
Dewalt black oxide drill bits
Milwaukee titanium
Bosch 10x life M42 cobalt
Irwin cobalt drill bits
Amazon HSS step drill
I have drilled 1/2 thick stainless steel and 1/2 forged steel door frame for big commercial building without problem. But that sink is the hardest metal ive ever drilled. I put some 3 in 1 oil and go slow with a drill (maybe 300-500 rpm) and put all my weight on it (i weight 270lbs). It barely make a groove in the metal. Every drills bits get dull after 5-10min drilling slow and taking break after 1min. Im trying to drill a pilot hole with 1/16 bits, 1/8 and 9/64. Im putting more pressure the bigger the bits is till i put all my weight on the 9/64. I need to make at least 1 hole put i would like 2.
