- Reviewed in Canada on June 14, 2025Verified PurchaseWhen on sale a great pickup for anyone who may need them
- Reviewed in Canada on September 21, 2023Verified PurchaseFirst of all, I really love the bits. They have a texture to them which I believe gets a little more grip on the screwhead. I’m mostly using the P2R2 combo bit, which is really versitile here in Canada.
I used the drill bits as well but they come loose while drilling using the included bit holder. I think if you’re going to be doing anything serious you’ll need another locking bit holder.
This kit really makes my basic Bosch electric drill so much more versatile and quicker to swap things out when I’m on a project.

5.0 out of 5 stars El estuche es lo mejor
Verified Purchasellevo con mi primer estuche cuatro años y continua siendo robusto sin ser pesado, practico y de buen cierre como el primer dia, ha soportado varias caidas incluso abierto y sostiene las brocas intactas, la verdad que solo estuche deberia valer mas de la mitad del precio sin problemas. En relacion con las brocas me duraron cuidandolas en varios trabajos, (se pagaron por si solas), me duraron aun mas y al final se quebraron probablemente mucha presion por falta de filo o un movimiento brusco del trabajo, pero cumplieron y ya tenían que jubilarse, en relacion con las puntas una de ellas se me quebro pero ya a un muy alto torque pero para el precio es muy bueno, incluye puntas pozidriv las cuales te sacan de varios apuros pues muchos sets de otras marcas incluso no las tienen. EL sujetador magnetico no es tan preciso al 100 por ciento, ya que no gira exacto en el centro pero aun asi pasa la prueba, en su lugar utilice el sujetador de bosch con retenedor de puntas ITBHQC201, con todo el anterior voy por mi segundo juego y si te lo recomiendo

5.0 out of 5 stars Quality since 1886 Bosch
Verified PurchaseNo brainer the 40-Piece Assorted Impact Tough Drill Drive Custom Case System Set for Drilling and Driving Applications.
The value is there, The quality is there, this 40 piece assortment of impact rated bits are a great replacement solution or addition to some 11 - 1 impact rated multi tools out there can you take a guess of the one I'm talking about as well as other 1/4 inch drivers alike accommodating this universal impact rated bit set by BOSCH.
The BOSCH DDMS40 are great for the DIYer and Trades People.
That's it from You TexasBoy I hope you found this quick review helpful and informative, happy shopping.
