Bosch Impact Tough Titanium Drill Bit Set
Drill bits are a staple of the jobsite because, well, something always needs a hole in it. You may think you need more drill bit information like you need a hole in the head, but not all coatings and treatments are well-suited for every job. I’ll use just about any bits, but I usually find myself buying titanium coated bits because they are a good general purpose bit as the coating reduces friction and heat. The 9-Piece Bosch Impact Tough Titanium Drill Bit Set was right up my alley.
The “Impact Tough” designation means the bits can be used in higher torque impact drills and drivers, which you can see if you look closely at the hex shank. Bosch claims tip is designed not to skate and the flutes are designed to quickly remove wood and metal waste. I put the bits to the test over several weeks as we continued work on a large home addition and some smaller projects.
Titanium drill bits are HSS bits that have been coated with titanium nitride (TiN) using a process similar to electroplating. TiN is a ceramic material that increases the surface hardness of the bit and provides a thermal barrier by reducing friction. This results in increased production rates, corrosion resistance, and 3 to 6 times longer tool life. Titanium bits like ones found in the Bosch Impact Tough Titanium Drill Bit Set are suitable for drilling iron, steel, aluminum, magnesium, and wood.
Titanium bits are great for general purpose drilling in a production environment because they drill quickly. The TiN coating also helps chips flow thru the flutes which is helpful because some materials – like aluminum – adhere to bits more than others. However, once the tip is dulled, it won’t regain it’s cutting edge without being recoated in titanium nitride. It usually makes more sense to replace rather than recoat them. So even though they are harder than cobalt, their edge is only skin-deep.
The Bosch Impact Tough Titanium Drill Bit Set includes 1/16-, 3/32-, 1/8-, 5/32-, 3/16-, 7/32-, 1/4-, 5/16-, and 3/8-inch bits which covers most of my needs around our jobsites.
The bits worked as advertised and did a fine job each time I needed them. I haven’t broken any yet – something I’ve done with just about every other titanium bit I’ve used. The waste went through the flutes quickly without filling up.
My favorite part is the impact ready design – in a drill or driver, these bits get the job done. The tips didn’t skate and the holes were accurate. I don’t know that I could ask much more from them.
The Bottom Line
For only about $20, I recommend the Bosch Impact Tough Titanium Drill Bit Set. The biggest gripe about them might not even be about the bits themselves – it’s that they don’t come in a case. But that doesn’t bother me. They are fast, accurate, and impact ready. You couldn’t ask for much more in a titanium bit. With Christmas right around the corner, these make a great stocking stuffer or just as an excuse to go out and buy a set for yourself.
