Bosch TI9IM 9 Pc. Impact Tough™ Titanium Nitride Coated Drill Bit Set

Works great, very strong, Ive never bought this brand before even though I know it to be a quality brand bit now after using it I am a big fan. No snapping even with adding great downward pressure on it. Went through the metal quickly and remained sharp, very happy with the price, exact in size. I love the quick release impact attachment so easy to use. Such durable steel, Ill be lo ok king to buy this brand more in the futire

great little drill bit. I will look into more of this design as needed.

A really solid, long lasting bit for drilling through metals. Long lasting and tough.

Longer lasting than Dewalt!. Best to use Milwaukee

Exelente calidad

I have a ryobi drill. Its the one that you can twist the handle to get it into a 90 or 180 degree unit. I needed to install a camera and somehow had every drill bit size but a 1/4in one. Thankfully, Amazon had this available. It shipped quickly, was cheaper than the big box store, and fit my ryobi drill perfectly. 10/10 easiest camera install.

So I have a drill bit kit that I've had for years made by Hitachi. It has drill bits ranging from 1/16in up to 1/4in. Over time I've broken several bits which I have tried to replace with OEM parts when available. When I wasn't able to find a Hitachi brand 1/4in, I opted for this Bosch 1/4-Inch Impact Tough Titanium Drill Bit for about $5 shipped to my door. The other day I needed to drill 4 holes 5/8in in diameter into my welding table which is made of 1/2in thick plate steel. I wanted to drill pilot holes with something smaller than the 5/8 so I grabbed this new Bosch 1/4in drill bit. I thought surely at the first pull of the trigger on my impact driver I would strip out this 1/4in drill bit from its hex shank. Let me tell you - I drilled all four pilot holes with this one 1/4in drill bit through 1/2in thick plate steel with no problems whatsoever. Sure I went slow .. 300-400 rpm maybe? And I stopped every couple minute or two to brush away the chips and give a squirt of oil to cool and lubricate. And when I was finished, I had four nice clean holes and the drill bit looked good as new. That just never happens to me! I highly recommend the Bosch TI2143IM 1/4-Inch Impact Tough Titanium Drill Bit. I'm going to buy at least one of each size to replenish all of the drill bits in my Hitachi kit. Good day to all!

I prefer these hex bits when using a holder thus allowing quick bit changes. I do not recommend if drilling hard materials. The issue is the shafts takes the punishment often snapping if the bit jams unlike a standard round shaft that will spin in the chuck.

Very good bit
