Great Qaulity
Excellent much better than the basic ones
User
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.
User
Perfect for hardened steel
Best drill bits I've ever used, cut straight through hardened steel without wearing out like cheaper bits.
User
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.

Good product excellent seller
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
