I used these to drill a number of things when fixing my motorcycle. Functional when drilling plastic and metal! A variety of things, no problems with it at all, and it seems extremely durable, like I could use these the rest of my life. Definitely worth it for the value.

Great drill bits! I ordered these to drill out rivets in the floor of my 18’ aluminum boat so I could replace the foam. With no room for error I needed a quality drill bit that wouldn’t walk. These did the task perfectly and lasted for a long time. Removed whole floor with only using two bits. I could have done it with one, but toward the end the first bit started to dull slightly. I will order more of these bits in different sizes in the future.

I’ve Wanted and Searched For 115 Piece HSS Cobalt Drill Bit Set For More than 5 Years! When Prime Days Came, I Thought I Was Getting a Great Deal, as The Normal Price Was Inflated Compared to What It’s Listed At Right Now! As It Is, I Saved $14! THE GREAT LIE, PRIME DAYS! The Price Was Suppose To Be 35% Below Normal Price, Plus a 10% Coupon! But, I Used the Product the Day After I Got It To Drill Out a Hardened Steel 10mm Bolt in My Engine, That I Managed To Snap Off! It Went through it Like Butter with Cutting Oil! Cleaned Up Easily to Return to It’s Place in the Box! Which Does Seem Pretty Sturdy But, We’ll See How it Holds Up in About 5-10 Years! I’m Wanting These to Be The Last Bits I Ever Buy! But, Like Most, We’ll See How the Smaller Bits Hold Up as They Tend to Snap Easily! At Least That’s Been My Experience Over 40 Years! What I Really Wish They Would Have Done, is Identified The Drill Bit Size, High Lighting 4mm to 12mm or What Ever is The Largest, on The Right Wing! The Bits Are Identified By Size on The Left Wing and The Back! I Don’t Know the Reason, They Couldn’t Provide More Information on The Right Wing Besides A-Z! It Would Make Things So Much Easier! Now I Have to Search The Internet for a Sizing Chart To Identify The Size Associated With The A-Z Drill Bits! Imagine, Having To Go To a Competitor Who Actually Provides Some Help & Insight to Their Customers! I Know There Are Some, That At Least Have a Chart for Download, About the Size of Their Bits, Including The Size of A-Z Bits! As I Said, I’ve Been Searching For a While! This Will Definitely Be On My Mind, If I’m Looking for Other Tools and GM Comes Up At a Possibility!

I had never used cobalt bits before, but a recent project requiring holes in very tough hardened steel required it. My normal bits wouldn't tough the stuff. These worked flawlessly

Perfect! When drilling metal doors you can't fix it if you drill too large. It's good to have a variety of sizes. Worth the money and the simple design of the container is great. Easy to find and use.

These drills are sharp and cut excellently. Great price for a great set. As others commented: it's a bit hard to read some of the drill sizes in the "wing" holders.
