*by G***E on July 22, 2020*

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!
