## Description

Irwin Industrial Tools 10234CB #4 Unibit 3/16- Inch – 7/8-Inch, 12-Steps Cobalt Step Drill Bit (1/16- Inch Steps) : desertcart.in: Industrial & Scientific

Review: This is the 3rd Irwin cobalt Unibit I've bought over the last few years. (3 various sizes) A quick summary: Irwin tools are dependable and are of very good quality. I know I can get the job done if I'm using an Irwin tool or bit. My last Unibit was used to drill 120 nickel sized holes into stainless steel plating. (about 1/8" thick) (used a drill press). I was in a hurry and didn't use any drilling oil. The Irwin survived that task but reached its limitation which was more than I expected. I bought this particular Irwin 10234CB to drill a 13/16" hole into my Weber 10020 Smokey Joe Silver Charcoal Grill, Black . I wanted to install a 3" River Country (RC-T3W) Adjustable Professional BBQ, Grill, Smoker Thermometer (50 to 550F) (see my photo on product page) and this Unibit did the job effortlessly. (ate through that lid like it was plastic) Irwin Unibits are pretty expensive compared to other brands, but if you want the very best and longevity, definitely get Irwin cobalt bits. *** Don't forget to use drilling oil (or any oil for that matter, even olive oil) to extend the life of your bits.
Review: Very good
