Description of 🔧 Drill America GLBCOX67 64 Extension: Enhanced Drilling Power for All Your Projects
Effective in drilling tough, high tensile strength materials like stainless steel, inconel and titanium. 135° split point tip prevents drill from walking. Round shanks allow use with a wide variety of tool holding systems. Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools. 6" overall length for drilling where extra length for reach is required.
Long drills in such smaller sizes are hard to find. I needed a LONG piece to install the bathroom accessory rails and this did the trick. Used it to drill about twelve holes in the shower stall material, whatever type of drywall was behind it, and in the studs. It did its job and didn't break under reasonable pressure. Very satisfied with the product.
I had to drill some pilot holes in the pressure machined frame members for 5" wood screws. Given the flexibility of this bit, I bought two and figured I probably would. I drilled about 40 holes without breaking the chisel. Also, the chisel was sharp and drilled holes quickly with my cordless drill.
Pros
Round shanks allow for a variety of tool holding systems
quite long small diameter drill bits available for a very reasonable price (at the time of this writing). BUT. CHECK THEM IF YOU YOU WILL RECEIVE AS THEY MAY NOT BE WHAT YOU ORDERED EVEN IF THE CONTAINER IS CORRECTLY LABELED FOR A PAIR OF 7/64" BITS, ONE OF WHICH FITS A 1/8" TURN BACK TO SEE WHAT I WANT would get. I'm glad I did. Resending was also mixed. Like sending back two 1/8" bits. (Or maybe I'll just keep them to myself and forfeit the refund.) Someone at Revain needs to review that…
