For anyone who enjoys do-it-yourself projects or working around the house, owning a quality drill bit set is essential. Having the right set should make it possible to work on a variety of tasks which can save money compared to hiring professional contractors. In order to choose the best drill bit set, there are some things to consider. These mainly include what type of materials the individual will work on and what size drill bits are needed. In addition, both the quality and price should be taken into account.

When looking at different sets, the first thing a person should think about is what types of materials he plans to work on. For example, some drill bits are only capable of drilling through wood, while others can also handle metal and concrete. If wood is the only material that will be used, then carbide and cobalt drill bits should work well. For dealing with metal, however, stronger drill bits made from titanium will be needed. If the individual will be working on concrete, then steel bits will be required.

The next thing to think about when looking for a drill bit set is what size bits the person needs. Some people only need small bits to drill simple holes in the wall, while others may need much larger ones for construction purposes. If only a narrow range of sizes is needed, then it's usually best to stick with a smaller drill bit set with no more than 30 bits. On the other hand, if a broad range of sizes is needed for multiple jobs, then it's typically best to find a set with substantially more drill bits. Looking at a variety of sets before making a purchase should help most people find an appropriate size for their needs.

Once the type, sizes and amount of drill bits needed have been established, it's time to think about the quality and price. While it's okay to skimp on some tools, it's typically not a good idea to do so on a drill bit set. This is especially true when buying a large scale set with a variety of drill bit sizes. Like many products, one gets what one pays for with a drill bit set, so it's usually best to pay a little more initially and have a longer lasting set. In order to find the best price, one should shop both online and in local hardware stores. Doing this should turn up a quality set at a reasonable price.

Thanks, anon245269, sincerely. This has always been an area of confusion for me, and were it not for you altruistically taking the time to correct this article (or, rather, to point out where it needs to be corrected), I would have taken Mr. Mann's claims at face value, and surely even passed these tips on to others at some point, thereby perpetuating the misinformation that confused me in the first place.

Anyway, I know, given the ubiquity of misinformation in the net, it's sometimes hard to find the motivation to post that sort of correction, so I figured the least you deserved was a bit of recognition for your trouble. Thanks again.

I don't know where you get your info from, but titanium drill bits are only good for drilling metals such as brass, soft steels and aluminum.

On the other hand, cobalt and carbide are designed for drilling hard and slippery metals such as stainless steel, nickel, phosphor bronze, cast iron, etc. That's why cobalt and carbide drill bits are so much more expensive than titanium and high-speed steel bits.

Titanium bits only have a thin surface coating of titanium over a carbon steel core, so when the titanium wears off, you're left with a high speed steel bit.

A cobalt bit, on the other hand, is solid all the way through, not coated, so it can be resharpened many times and still provide the same performance.

You can easily verify this via a simple web search.

So cobalt is the better choice for long-term usage in hard metals.
