COMOWARE Titanium Step Drill Bit (5PCS), Black & Gold, HSS Step Bit with Two Flutes, 50 Sizes from 3/16" to 1-3/8", Steps Bits for Metal, Aluminum, Wood & Plastic, Unibit for Electricians & DIY

This bit worked great. I drilled 6 holes in the door of my RV to install new mirrors with no problem. I was skeptical because of the low price, but surprised and happy with how well it worked.

Good quality

Good for the price

Purchased to drill hole for drain hose connection in galvanized aluminum tank. Worked great with no visible wear on bit.

Not industrial quality, but for the price very good and will work for most non commercial jobs.I love it.

Delivered promptly! I needed hole in fairly thick aluminum and it worked as it should. My need and use was for a specific purpose and wasn’t needed or intended for daily work so I cannot attest to its longevity. It served it’s purpose for me.

For a few holes it was o.k. Didn't cut as aggressively as the name brand step drills. Took some effort to get it to cut. For a couple holes it's o.k.

I really only needed this for ONE USE, but the price was right compared to hardware stores! It's sharp and will cut through my BBQ wall to install a cold smoker.
