Cobalt drill bits
Quality sharp metal steel drill bits for the workshop. Bosch= Good Quality.

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.

Not good as advertised
Lot of money to not even touch it’s intended target doesn’t drill hard bolts

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.

I’m a hobbyist using these drill bits for steel, copper, and general household fixes and I’ve found them to be extremely durable and reliable. I’ve had no issues so far. The edges have held up well and consistently produce clean, precise holes. They’re well worth the investment in my opinion. The seller also provided excellent customer service. They stayed on top of the delivery and even sent a replacement when the package didn’t arrive by the designated time, without me having to reach out at all. Overall, a great product from Bosch and an excellent seller! Definitely would buy more if needed in the future
