About BOSCH CO14B 14-Piece Assorted Set
Overall Feedback:
85% positive
80% appreciated its precise drilling accuracy, though 20% experienced deviation
I was amazed that the drill bit could penetrate and drill through the steel with moderate effort.
I faced difficulty while drilling the last 6 holes and all the bits got dull pretty fast. I expected more durability from the bits as they are supposed to be used for metal.
79% praised for its fast drilling speed, while 21% found it slow
I found that the drilling speed of the bit was fast and the cut was clean. The durability of the bit exceeded expectations.
The last 6 holes took a long time to drill.
80% liked its long-lasting durability, but 20% experienced frequent breakage
I like the durability of the bits and the range of sizes. The tips are tough enough to handle the tough tasks I have to perform.
I am currently happy with the product, but will update about longevity later.
I will update the review if I face any durability issues.
I am disappointed with the durability of the drill bits. They were supposed to be used for metal but performed poorly and got dull quickly.

79% liked the comfortable grip design, while 21% found it slippery
The case is made of cheap plastic and it's hard to reinsert bits correctly.
81% found it resistant to heat buildup, but 19% experienced thermal damage
All the bits I tried got dull pretty fast, indicating poor heat resistance.
83% praised for its versatility in drilling various materials, though 17% had difficulty with metal
These drill bits are not ideal for softer materials like wood and plastics, but they will still work.
I like that it comes with multiples of some sizes, the durability of the bits, the range in sizes, and the toughness of the tips. I use them in all different types of wood and laminate doors and frames, steal and aluminum doors and frames in commercial security situations.
I like that the Bosch bit rarely leaves a burr on the exit side, making it easier to remove and showcasing the material versatility of the jobber-drill-bits.
I am disappointed that the shank lost its square edges with little use on a small machine drilling through relatively soft material, implying that the drill bits were not durable enough for the task.
