HSS stands for High Speed Steel. Which is a type of high catrbon steel. Cobalt, as I understand it, is a coating like Titanium coated bits. Cobalt bits can cut harder materials than HSS, or Titanium coated bits. I reserve using these bits for harder steels.

With the use of an oil they cut through wrought iron and stainless with no problem. You may have to make a smaller starter hole first. I really like them.

cut thru stainless with household cordless drill?

I think it would. You may want to drill a pilot hole and step up incrementally (depending on how big you're going). And use you're biggest battery, if you have that option.

This is absolutely the best drill set for the money...
This is absolutely the best drill set for the money I’ve been able to find anywhere! You can tell by the weight of the bits that they have a substantial amount of cobalt. So why only 5-stars??? It’s the incredibly bad case. The plastic grips the bits so tightly that pliers are needed to remove them. This is clearly a marketing ploy; the shiny red plastic looks great in a display and it must be cheaper to supply. But shame on Milwaukee; the merits of a shiny display are IMMEDIATELY lost when the bits need to be used. Fortunately, there is a remedy; just invert the bits in the case. Most of the holes require enlargement as most of the bits have reduced shanks but you have the bits right there! Buy these bits, give Milwaukee’s marketing staff a wave of your index finger, and don’t look back!

Snapped to bits
Just picked up a brand new set, a 3/8ths drill bit in a drill, pre drilled hole snapped the bit before one full revelation drilling aluminum. I want slow and the hole was 95+ percent predrilled. Look elsewhere for drill bits

Great all purpose bits
[This review was collected as part of a promotion.] This 15 piece cobalt drill bit set is perfect for your average Joe or for a handy man. The carrying case is heavy duty and convenient for storage and transportation. The bits are not easy to tug out, but they also don’t jostle around at all. The bits in the case pivot forward to allow for easy access and replacement. The performance of the actual bits themselves is great, I have been satisfied with the results. Overall a great functional product ! Highly recommend.

I love that they can be used on wood, stainless steel, black pipe and thick metals. I used it to put a subfloor on my bedroom floor. They worked great . They are super strong and did not break or strip my screws. They are durable love the precision.

Great bits
[This review was collected as part of a promotion.] These bits get right through and so far no issues with durability. This set comes with a good variety of sizes and in a helpful organizing case. But mostly what you need to know is, they work and won't snap.

Like butter....
[This review was collected as part of a promotion.] ....ok, so I realize that you have to use these for a few times to be able to comment on how effective and lasting they are so take this review w/ a grain of salt. I've only used them a few times. I did cut into some 1/8" thick aluminum and it cut through like butter. the bit didn't slip at all, cut right through and left a very clean hole. I took a video but can't seem to load it. Carrying case is nice too...I have another one that has a slide latch that is all jacked up, this one doesn't look like it'll do that but that's pretty minor. Overall, big fan of these bits.

Milwaukee Tool is a brand I trust
[This review was collected as part of a promotion.] Milwaukee Tool is a company that I’ve always trusted. In my line of work I use tools and they need to be reliable. Milwaukee is always the best quality and last me the longest. The 15 piece Helix Red set is exactly what I expected from Milwaukee. The drill bits are strong and work perfectly. The quality is always top notch. These drill bits can go through almost any material with no problem. They are easy to attach and look great too. When it comes to my career I want the absolute best. Milwaukee is a must in my line of field.

Sturdy
[This review was collected as part of a promotion.] I got these a while back and have used them several times. They are sturdy and cut nicely on multie types of materials. The bits are made of cobalt. It comes with an assortment of sizes also. The bits themselves also grip very well to the drill.

Well Made and Sturdy
[This review was collected as part of a promotion.] I work in a shop and regularly drill wood and sheet metal. This set is perfect. I used them all day yesterday including through the metal and the bits stayed sharp and didn’t break. The case is also good to keep the bits organized with clear labeling.
