What Customers Are Saying

Customers report sharply divided experiences with these drill bits. Many praise their sharpness, effectiveness in metal and wood, and convenient hex shank design, noting they drill clean holes and last long when they perform well. However, a substantial number report sudden, unexpected breakage under light pressure or during routine use in common materials like wood and aluminum, with some breaking on first use. Several cite brittleness and safety concerns when used in impact drills. A few mention they work best in controlled conditions like drill presses. Overall, performance appears highly inconsistent across users.

WRONG DRILL BIT, LOWE'S

Would Recommend

THE drill bit I purchased was a Bosch Bulldog Xtreme 8 (8 cutter carbide head), 1/2"X6". I'm going to use it to drill 2 holes in the concrete cover of the opening of my concrete septic tank so I can install a ubolt to lift the top off the tank when having it pumped out. The original ubolt was cast into the cover and has rotted out. It's worrisome to me that Lowe's systems would identify the incorrect item as my purchase. And I'm a Lowe's stockholder!!

Put the new 1/2 in bit in right thru the aluminum hit the alloy steel and nothing a complete dead stop mind you this was the very first hole was using a cutting oil and wasnt over heating the bit but she just flat out refused to go thru the steel. So after much cussing I went ...

Long, brittle bits. Use only in drill press.

Would Not Recommend

They broke very easily when used in a hand drill. Might work okay in a drill press. They cost little and still provided decent value.

The Tin coat is my go-to and the 1/4" hex shank means it fits pretty much any chuck.
