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
