No era lo que esperaba muy caras y son de medida muy pequeñas, no llegan ni alos 10mm. Yo buscaba de 8mm. sta 14mm. Pero la descripción está muy confusa

Works well

Good drill bits. They cut through metal (stainless steal sheet metal) with no problem. Good quality bits and good value for the price. The plastic case is a bit flimsy though.

5 Starts all day! These bits drilled threw a thick stainless steel sink with the greatest of ease. Made the install quick and easy. Highly recommend!!!

I love a good drill bit set. There is something deeply satisfying about opening a fresh case of organized bits—it makes me feel like I can build a deck, fix the car, or at least hang a picture frame without putting 14 unnecessary holes in the drywall. This set is almost perfect. The Good: The case is sturdy and holds the bits tighter than I hold onto the thermostat setting in the winter. The larger bits are absolute beasts; they chewed through wood and mild steel like it was butter. The "Eh, Needs Work": I knocked off a star because of the smaller gauge bits. I tried to drill a pilot hole into a stainless steel bracket, and the small bit just sort of spun around on the surface like a breakdancer. It didn't "bite" at all. It was less of a "drill" and more of a "friction heater." Summary: Durability: High (for the big ones). Value: Great for the price. Performance: 90% excellent. Just be warned: if you need to do fine detail work on hardened stainless steel, the little bits might give you the silent treatment. Still, a solid addition to the toolbox. I’d tell you a joke about a drill, but it’s boring.
