### ⭐⭐⭐⭐⭐ Perfect for the job
*by L***G on November 17, 2025*

Is exactly as expected, worked great did the job 12 other bits couldn't!! I have a shop so I get many tools. These held up to the hype. Cut through engine block exhaust bolt. Bolt broken in block.

### ⭐⭐⭐⭐⭐ Made holes where I wanted them
*by A***6 on January 2, 2026*

I drilled over 50 holes into a 1" steel tube. I used a drill press and lubricated the bit with cutting oil before each hole. Bit worked great. No slipping on the rounded surface. Cut the steel with little pressure. Easy to hit my mark.
