Good value for the money.

Have used a few times on electrical cabinets, galvanized boxes and thin stainless steel. I've kept it well lubed during use w/ high viscosity cutting fluid and haven't noticed any dulling or overheating. I like the large size because I can drill one or two holes quickly and the mass serves as a heat sink keeping the cutting edge cool, after that it gets put away till next time.

Doesn't have the feel or weight of higher quality bits so I don't know how it would handle extended use, but that's not what I need anyways. This gets the job done and is good enough since it gets used very sparingly and I saved a bunch of money to boot.

This review is from: Neiko Titanium Step Drill Bit - 1/4" to 1-3/8" in 1/8" Increments, 10 Steps (Misc.)

I needed to drill a 1-3/8" hole in a stainless steel kitchen sink (not sure of the thickness, but it was a heavier gauge than some of the less expensive sinks I've seen) for an instant hot water device. I had another step bit that wouldn't touch it. This one did the job, albeit with some time and effort. I started with a 1/8" bit and worked up to 3/8" or 1/2" (I forget which) before using the step bit. Then, I drilled one step at a time using liberal amounts of cutting oil, it cut slower as the hole got bigger which makes sense as it was working harder to remove more material. The key to the job was letting the sink and bit cool down between steps (cool water helped speed up the process and also kept the sink from warping). I had my wife drizzle oil on the bit/sink while I drilled - messy but effective. Bit seems to have survived just fine, still feels nice and sharp. As an aside, we love the instahot, too - it was worth the effort!

5.0 out of 5 stars Stainless steel = butter, December 13, 2010

This cut through a large stainless steel kettle like butter. Can't attest to how long it will last but I see no reason why it would not last for a couple dozen holes. Just make sure to use low RPM and a quality cutting fluid like Tap-Magic extra thick. Excellent product for the price and a good tool to have in the homeowner/hobbyist arsenal.
