Harbor Freight step drills ain't the best quality, but they're fine for DIY use, and especially plastics.

Step drills are kinda handy to have around in general too.

When I use step drills in sheet metal I generally drill a pilot hole using a standard twist drill. Doing that helps the step drills last a bit longer without resharpening.

I find that step drills are more efficient with plastics than are regular twist drills. Twist drills can grab and may cause additional stress.
