Review on Double Carbide 0 118 Rotary Cutting by Tommy Willis

All I did was resize those 2 holes from 7/16" to 1/2". Standard 1/4 inch A992 mild steel. Done with this exercise. And I didn't even finish it to 1/2 inch hole diameter. I have used many burrs. But nobody talked about a product like TAITA. I'm very disappointed, I expected more for the price. AS I HAVE SEEN THE REVIEWS PROVIDED. I SHOULD NOT HAVE CHIPS IN THIS 10X BURR BIT. BUY AMERICAN! EVEN IF THEY ARE THE CHEAPEST, IT LASTS LONG. ADDITIONAL $32.00 PER 10 PIECES MILLS 1/8 ALSO WITH WARRANTY. THAT I SEND THE BITS BACK AFTER EVERY HOLE I INCREASE 1/16. NOT FOR THIS PRICE! DISAPPOINTMENT.
