🔧 Bosch CO14B PC Cobalt Drill: Versatile and Powerful Precision Tool Review

I had to drill through a stainless steel sheet, actually the license plate holder on my Ducati. I tried some cheap drill bits I had at home but there were no dice. Bosch cobalt drills went through. I did a little research and learned how to use the drill at a lower speed and it worked like clockwork. These are high quality drill bits that are important when working with very hard materials like stainless steel. This is a great product.

For a long time I couldn't decide which brand of drill bits to choose until I chose BOSH, they seemed good quality to me, but upon receipt I quickly realized that the little bits were missing a point, they look flat, they slip on the metal when drilling. The big bits don't seem to be centered when I drill into the metal, it's a triangular shape as you can see in the photo. They appear to be of good quality but it seems I touched a faulty batch. I would like other bits in good condition and a…

I tried to drill a drywall screw, but the 1/4 inch drill didn't go through the screw. I called Bosch and they told me the drywall screws were too hard for these drills. I drilled a few holes in an aluminum rod about 1/4" thick with no problems other than a drywall screw! This was my last Bosch purchase. I admit the rep I spoke to was nice, he let me make that one Stopping work to find out why these bits wouldn't drill through a drywall screw.I was told to use a black onyx bit because of the…

Worst of all, two of these drills, the largest and the third largest, each used less than 1/2 dozen times, are ripped out. The bases of both in this location are so rounded that they can no longer even be held in a drill. This is a regular Cal Hawk 10" drill bit and I have not used the larger drill bits for drilling anything other than mild steel. by a relatively soft material. And then I find out that Bosch only gives a 30-day guarantee on these ultra-high-quality drills! Now I have to buy a…

I've struggled with DeFawlt and other big shop bit sets for a few years now. I've never had any luck as they don't feel like they cut much, dull quickly or break easily. I didn't want to pay for Drill Hog's work and the price of Drill America's bits fluctuated too much so I settled on about $30 which is pretty comparable to the regular sets I buy from Slome Despot . Cobalt! I love her! They cut like ordinary steel - it's butter. They have non-slip shanks so you can put them straight in without…

Received a 3/8" cobalt drill bit from Bosch yesterday morning and drilled ten holes in 2" 6 foot thick sheet steel. bar for about 45 minutes yesterday afternoon. The beam is used to reinforce the wooden roof beam on a small porch (bolted to the side of the wooden beam). I spent most of my time changing the rod's position for each subsequent hole, and the actual drilling time for each hole was about a minute. I used a small Rockwell drill that I bought from Revain last spring and now sells for…

My Ironman Ellipse driveshaft bolt broke in the flywheel bracket. The bolt was screwed onto the shaft and would not come out. I can't find a replacement shaft, so my only option was to drill out the center of the broken bolt and use a puller to pull it out. I set the drill to the lowest speed and used cutting fluid. I bought a set of cobalt tips from Milwaukee (Home Depot) that barely scratch the surface. Found they weren't even sharp out of the box! Used a sharpener and cutting oil to make…
