13pcs Hex Shank Drill Bit Set, Professional HSS Nitriding Twist Drill Bits, Upgrade Black and Gold Coated Drill Bit, Quick Change Design for Wood, Steel, Metal, and Plastic, 1/16IN to 1/4IN.

Great for the price. Just be careful the smaller ones are very fragile.

I love these drill bits you don;t have to keep adjusting the shank they are all the same size plus you get a handy case as well. They work just fine for my needs I am a happy camper.

Hex shank broke off of 1/4 inch bit on the second of two holes I was drilling in a metal sheet that was only 1/32 inch thick and was locked in a vice. I use quick-release bit holders and have for years. I've never had this happen on any hex shank bit I've used. Since I do not have transportation, the cost to return the item was going to be more than the cost of the item itself. Total waste of money. I am very disappointed in this purchase. If I could give it a lower rating, I would. Weeks after first review and still experiencing defective bits. Now the hex end separated from a bit first time I used this particular bit. Company would be wise to remove such poor quality merchandise from the market. Shameful.

Excellent set. I used them often with my small portable drill that only takes hex shank drill bits. Durable, easy to keep organized. Used for household work not professional use so can't comment on the later.

Not very sharp

Quality seems good, over sharp and coating is good

Low quality, broke after only a couple uses

Good drill bit
