well worth paying a bit more for quality
Normally use cheap drill bits but all the ones I had really struggled when drilling out a bolt. These ones made my life so much easier and saved me a lot of time. Always use a bit of cutting oil/spray when drilling metal and these are still sharp after use and hardly a scratch on them.

Decent bits but be aware they're not metric
At the time of buying it wasn't obvious they were standard size not metric. They still seem like quality bits and drill steel like butter.

Bosch and Cobalt - what more could you want..?
This is a comprehensive range of sizes in a sturdy case - with the added benefits of being Bosch-built, of Cobalt steel, so they should stay sharper, longer. When drilling steel or harder materials, it is always worth getting the drilling speed right for the work - and using copious quantities of drilling lubricant (if necessary), to cool the drilling area. Thus especially applies when you have invested in a set like this.
