STROTON 5% Cobalt Drill Bit Set (1/16-3/8 Inch, 21PCS) for Stainless Steel, Hard Metal, Cast Iron, Plastic and Wood, M35 Hss Heavy Duty Twist Steel Drill Bits Index.

I have been through just about every namebrand out there on drillbits, but I really appreciate the Stroton approach. They are fully aware of the competition, and stay right on top of their game. I was so frustrated because I broke one of their drillbits.. It was a brand, new drillbit, and I got a bunch of holes to drill and tap. Making my own TV stand that swings away, from angle iron. Anyway, I thought it would be a hassle trying to get them to replace that drillbit. They responded to the message I sent through Amazon in like an hour! They replaced the whole set of drillbits…! I was a little bit shocked by that. Nowdays, it seems like everybody just sells cheap China crap, grabs your money right up out of the bank in two seconds, knowing that they chumped you, and just laughs at you. Stroton is one of those companies that planned on being here to stay, and for that reason, I’m gonna stay loyal to them because that is the kind of America that I grew up with. These guys are bad dogs off the chain, and there’s no stopping them. The products are bulletproof, and I got nothing, nothing, to ever say bad about them. If you are not already a fanatic about their approach… You will be if you give them a shot. I genuinely vouch for these guys, they are exceptional.

Cobalt is supposed to be the sharpest metal out there for drill bits, but they tend to be brittle if you put a lot of pressure while your drilling your hole. The smaller the bit, the easier it will be to break, so be careful. Still, the bits are really good for drilling stainless steel and other tough metals.

I had some heavy duty drilling projects but had inadequate bits to tackle the jobs. A friend recommended these bits from Stroton so I jumped on them. I like the full set since there is always something that needs a hole of various sizes. Their warranty is something else and comments by other customers make it clear that Stroton lives up to their promises. For a US made product, who would not want to buy these bits? Thanks, Stroton.

I love them. I will buy them again.they r great

The metal is amazing they must be made in the USA or Germany this ain't Chinese crap
