Whats its the right bit for hard metal?

Well, first off, do not use these for metal; they're for concrete. I don't know how hard the metal you're trying to drill is, but any Titianium Nitride coated drill bit or cobalt bit can drill through metal. In addition to Titanium Nitride TiN, you can use Black Oxide drill bits, Cobalt, and HHS drill bits. It depends on the material the drill bit is made of and the metal you're trying to drill through.

No. These bits have a carbide tip with diamond dust mixed into the carbide. They are designed for use in a hammer drill on concrete, block, brick, etc. For hard metal, you want a high speed drill marked "HSS" or titanium tips are better and you use cutting oil at the point of the drill while drilling. Get something like the Chicago Latrobe 150 Series High-Speed Steel Jobber Length Drill Bit Set with Metal Case, Black Oxide Finish, 118 Degree Conventional Point, Inch, 29-piece, 1/16" - 1/2" in 1/64" increments.

These are for masonry/concrete drilling. They are carbide insert bits. You need HSS or Cobalt (preferable) for hard metal such as carbon steel or stainless. Anneal the metal before drilling if possible and heat treat afterwards.

I have found that cobalt drill bits work best for stainless steel another very hard metals. Something to remember though, the speed of your drill motor and a good cutting oil, will make the job much easier and lengthen the life of your drill bit.

The answer is 7/8" and the bit should be one of the round ones with teeth not the flat ones that gouge in wood.

It is meant for the synthetic stock. I'd return bit and go to the manufacturers website to find the right unit.

I would recommend a non pilot pint bit it acts like a screw pulling the bit through material faster than the drill can spin it. Mad dog drill bits makes a good set for a little more cost

It has been a very good tool for me. I've tried it for wood mostly, but I believe the type of bit you would need would be different for concrete and metal.

Normal. The silver thing in front is a chuck. You won't be doing any heavy drilling with a large sized bit anyway. It's only for very light work.

Any standard bit will work in this. It comes with a special tool to take bits on and off.

If you buy the bit adapter you can use standard small shank SDS bits. This unit is made for the larger shank bits. I have the adapter but I also use both sizes if bits. It is a great hammer drill. I am a General Contractor and it is a great addition to our work.

I bought these specifically for metal and they are excellent. For concrete, I would choose bits specific for masonry.

The size you have that's close to,but under 1/2 inch. This will also help in not splitting the wood. If you have a 3/8 wood bore bit that's the best

yes most or bits for metal can be used on wood but not vice versa. Some wood bits are for wood only for example forstner bits

This set is a drilbit tip with tapping feature after drill is started. All in one bit. Its good for drill/tap ping electrical panels and other lighter gauge metals. Not sure what your looking to do

Yes these bits will drill metal. However as with any drill bit a good cutting oil is necessary to keep the drill bit cool.

I never used it. Bit May be for situations where there is not much threading on pipe. I just use a little plumbers tape and screwed it on

if i was going to try i would get a separate set of just drill bits, anything steel alloy seems to get good ratings, and i would drill a hole before running these through something that thick, one inch would be about the max, since the bits are only a few inches long and the threading teeth start about a half inch in. Just keep in mind any expensive small drill bits will still break if you don't take your time working with metal.

All you should need is a good bi-metallic drill bit. I had not problem, just make sure you use a small center punch to make a dimple so the drill bit does not walk and ruin the finish. Just a small dimple don't go overboard and make a big one.

The index that holds the bits is a hard plastic. Read my review - For your safety, unless you only drill wood these are too aggressive a cut and they tend to grab the work piece and can twist it in your hands.
