## Description

Drill Hulk cobalt M35 left hand drill bits are made from high-speed steel and 5% cobalt. The addition of cobalt improves strong durable performance in harder materials. Made in China. You Will Get: 2pcs 5/64 inch, 2pcs 7/64 inch, 1pc 5/32 inch, 1pc 1/4 inch and 1pc 19/64 inch cobalt left hand drill bits with case. Warning: Drill bits can shatter during use. Always wear safety goggles and safety items when drilling.

Review: Fast, sharp, functional. - Never Know with desertcart tools. Theses left hand bits cut through German steel like butter. Hoped it would catch and unscrew the broken screw I was working on . Once the pilot was done, a quick enlargement and a easyout finished the job. Bits are functionally sharp, as far as durability, hopefully I won't need them often. I'd buy them again.
Review: Drilled through a graded bolt with ease! - These are fantastic drill bits! I had a broken 8.8 bolt inside the recessed end of the crankshaft on my RZR. I carefully drilled far enough into the bolt to spin it out with an extractor. If this hadn’t worked I’d have had to pull the engine.

### ⭐⭐⭐⭐⭐ Fast, sharp, functional.
*by S***. on December 28, 2025*

Never Know with Amazon tools. Theses left hand bits cut through German steel like butter. Hoped it would catch and unscrew the broken screw I was working on .

### ⭐⭐⭐⭐⭐ Drilled through a graded bolt with ease!
*by D***N on February 7, 2026*

These are fantastic drill bits! I had a broken 8.8 bolt inside the recessed end of the crankshaft on my RZR. I carefully drilled far enough into the bolt to spin it out with an extractor. If this hadn’t worked I’d have had to pull the engine.

### ⭐⭐⭐⭐⭐ Worked fine for drilling out the broken set screws on a couple of hose bib backflow valves.
*by D***D on October 22, 2025*

These are made in China, but worked pretty good to drill out the broken set screws in a couple of the hose bib backflow valves that came with my house. I used a 5/64" and 1/8" drill bit to drill out the set screws completely, using a 3,000 rpm drill and progressing slowly so as to not drill through the hose bib. You can feel when the set screw has been drilled out and you've reached the softer brass of the hose bib threads. The reason I got these left hand drill bits was in the hope that the set screws would catch during the drilling and unscrew themselves, which they didn't, but at least they didn't tighten any more as they might have with a right hand drill bit.
