BL9IM 9-Piece Assorted Set Black Oxide Metal Drill Bits Impact Tough with Impact-Rated Hex Shank for Applications in Steel, Copper, Aluminum, Brass, Oak, MDF, Pine, PVC and More

I bought these as a stocking stuffer for husband; he's very happy with the quality and variety of drill bits all in one. They are holding up great, no complaints.

These drill bits are some of the better drill bits I have used. Very happy, and the drill bits work very well compared to the previous 4 sets from other brands I recently purchased. Downside is there is no case. A little weird a case is missing, but not too bad.

They're Bosch, so the bits are tough. They are also very convenient when a job calls for frequently swapping bits. The problem is they're kind of wobbly - which you would expect from any hex attachment tools or bits. If you can live with the slight wobble, they're great.

The bits were able to successfully drill through various metals, allowed me to accurately make holes without drifting at the start and survived to work again other days. I am very impressed with their performance.

Bought these to use with my Porter Cable impact driver (also from Amazon). I tried bits from Harbor Freight and Walmart, and swept up a lot of broken bits. I subjected these bits to the same tasks with no problems at all -- and they went though ⅛" steel strap like cheese. Hard cheese, but cheese. Part of the durability might be connected to the short length -- the smaller bits in this set are about half the length of the comparable bits in the cheaper sets. OTOH, they all look long enough for any likely purpose.

Drilled through cheap plastic without shattering it. Drilled through leather easily, too.

Small ones are very easy to break

I will purchase from supplier again.

Igual a la imagen los compre mas que todo por la marca Bosch. Tienen muy buenos productos y nunca me han fallado.

Produto top, brocas muito afiada só achei um pouco salgado o preço comprei para usar em parafusadeira comum acredito que vai durar muito mais, Pois ela suporta impacto sem impacto acredito que vai durar no mínimo três vezes mais.

Bosch one word.

Me gusto el desempeño y la variedad del paquete

Realmente torna preciso o uso, a ponta não escorrega e facilita muito o uso. A qualidade parece muito boa, de que vai durar.
