REVIEW: No-Brand Step Drill Bit Set
“Fairly Good Value for the Price”

Note
This is one in a series of reviews I’ve written of products I’ve bought from Amazon and which were originally published on that site. I’ve moved them here because Amazon don’t pay me to write reviews for them and I don’t work for multinational corporations for nothing.

Even though these were a bit of a cheap 'no-brand' set [3 for the price of 1 well-known branded] I thought I’d take a punt, as the reviews were pretty good.

Impressions are mostly favourable. I’ve drilled a fair few holes [mostly in coins, so a variety of materials; steel, cupro-nickel, copper, etc] in metal of thicknesses up to a mm or two and they seem to have held up well. Nothing to indicate they are losing their sharpness so far. So top marks on that front.

On the downside though, I think the profile of the bits could maybe do with being a bit less aggressive [maybe 4 slots instead of two] as, especially on the bigger sizes, they do have a tendency to catch when the bit jumps from one step size to the next one up. So I quite often have to back the bit out [luckily my drill has a reverse setting] and then try to gently persuade it to drill out the next hole size without sticking again.

I’ve also found that, although I start all my holes dead centre via a pilot hole, they do tend to have drifted off by a wee fraction each time. That may just be me being cac-handed and, obviously, its more noticeable when drilling on something wee like a coin than into something the size of a car or building where half a mm either way isn’t usually going to make much difference.
