GMTOOLS 13Pcs Cobalt Drill Bits Set, M35 HSS 135 Degree Tip, Twist Jobber Length Drill Bit Kit for Hardened Metal, Cast Iron, Stainless Steel, Plastic and Wood with Storage Case 1/16"-1/4"

Nice quality and a great price. I had a lot of drill bit that were getting dull and this allowed me to replace all of them at once.

I didn’t realize my old drill bits were so dull until I got these. Work well.

I picked up this cobalt drill bit set because I was tired of constantly hunting for the right size bit or replacing cheap bits that dulled too quickly. After using this set on several projects, I'm very happy with the purchase. The metal storage case keeps everything organized and makes it easy to find the size I need. I've used the bits on steel, aluminum, plastic, and wood, and they've performed well across the board. The bits cut cleanly and seem to hold their edge much better than some of the basic sets I've owned in the past. I recently used them while working on a vehicle project that required drilling through thicker metal, and they handled the job without any issues. The 135-degree split point helps the bit start accurately and reduces wandering, which is always appreciated. Having such a wide range of sizes in one kit has been extremely convenient. The quality feels good, the case is sturdy, and the set offers excellent value for the money. It's become one of those tool sets I find myself reaching for all the time.

Bit’s are sharp and appear to hold an edge; I have only used two Bits out of the index and both worked well. Index box is thin and deforms easily, latch is not trustworthy. Good bits, poor quality box.

Well i broke one bit, but for the money they're pretty solid considering im going through cold rolled steel thats a 1/4" thick. Also, if youre going through any solid metal such as steel, dip the bits in oil at the tip to help with the heat

I have purchased several of these for projects and work. The quality of the cobalt alloy bits is good for the price, and the selection of sizes has no gaps as far as I can tell and are well labeled inside the case.

Cut through 3/16" mild steel plate like a hot knife through butter 👌🏽

The small bits chipped pretty easily. It does seem like they should be good but they didn't last for me. I was drilling out a stainless steel bolt that is stuck in a suspension piece in my truck.

These bit are most excellent and cut very fast. I will rebuy from this seller just for the quality and quick delivery

Increíblemente buenas, un excelente filo las e probado en aceros tratados y sin problema perforan, recomendado al 100%

Si es bastante resistente lo uso para barrenos en aluminio.l

Très beau produit, hâte de l'essayer !!!

I would give them more stars if I could. I have 2 drill sets and broke 3 drill bits trying to drill a hole. Came across this set and ordered it. 1 bit, multiple holes and it still cuts like it was new. Would strongly recommend them if you are looking for something that will last.
