You mean the Warrior step drill bit set [harborfreight.com] at Harbor Freight? The Warrior step drill bit set is titanium, not cobalt. Thus not comparable, as cobalt drill bits are more expensive.

HF also has the Hercules cobalt steel step drill bit set [harborfreight.com], which I think is comparable to the Klutch set (this deal), but costs more than twice as much ($34.99 vs $15).

I use them to drill through firewalls to run car electronics wire. A regular drill bit usually races through after the hole is made, possibly stabbing something on the other side. These do not. They're also one size fits all kinda thing. Always reach for the same tool, make the hole whatever size I need, snap in a grommet, run the wire.
Ā·
They are inherently good at drilling large diameter holes in thin material. Normal twist bit drills are great when drilling into material that is several times deeper than the diameter of the hole. However, if you need to drill a 1/2" hole in say 1/16" plastic (the first time I used on of these bits) a twist bit is likely to result in a total mess. Step bits avoid these issues. I have some HF cheapies and an Irwin step bit. When drilling metal there is a difference. Not so much for plastic.

Ouch. Those look like some very painful butt plugs.

Cobalt coated

The KlutchĀ® Cobalt Step Drill Bit Set in high-speed, heavy-duty steel with cobalt coating is a great choice for contract work and homespun projects alike. This set includes a 3/16ā€“1/2in. dia., 6-step bit; a 1/4ā€“3/4in. dia., 9-step bit and a 1/8ā€“1/2in. dia., 13-step bit.

I'll add the example of adding a faucet hole to a metal kitchen sink.

These claim to be cobalt steel with titanium coating.

Came here to say the same. Used to do car audio and accessories for a living in the 90s - 00s... drilled many a firewall with a step bit and a right angle drill (at the time a 9.6v from makita... I still have that drill 30yrs later.. batteries are dead cheap now šŸ¤£)

Cheaper isn't always better on step bits... if you do go cheap.. I would suggest putting a dimple in the metal or drilling a pilot hole first. Otherwise, you may walk it. Cheap also means the tips may/will dull out quickly or fracture under stress. If the tips dull/break, drill a pilot hole as the rest of the step bit is most likely still good to go. I have a couple of small broken step bits I still use after drilling the pilot hole.

However, if only using it occasionally, cheap is more than suitable for most thin metal, abs, wood jobs.

These are probably OK but Dub Step bits sound so much better when you use them.

Probably good for an occassional need but daily/weekly use not so much.

These are great for increasing the diameter of a pre existing hole. I use these daily in the electrical trade.
