The proper drill bit for the job.
There are many types of drill bits, it can be confusing as to which one is the right bit for the job. Today I want to show you the different types of bits, and there uses.
First, know there is a bit made for whatever you need to put a hole in.
The most common drill bit is the standard metal cutting bit. These bits are very versatile. They work well in just about every material such as metal, plastics, and wood, up to about ¾” in diameter.
There are other types of bits that are made for drilling through metal. Step drills are one of my favorite. They can be used to drill many different diameter holes. The one draw back is they will only drill through material up to about ¼”. There are also hole-saws made for metal, they are expensive comparatively, but they work well for holes smaller than 3” in diameter and less than 1/16” thick.
Drilling through wood you have more options. Typically you will be drilling larger diameter holes in wood than in metal. Paddle bits are fast and readily available. They work well for holes 1 ½” diameter x 1 ½” deep and smaller. Auger bits will do the same diameter as paddle bits but drill much deeper, so drilling through thicker materials is much easer. If however you need holes larger than 1 ½”, hole-saws are the best way to go. These like the rest have there limitations. I personally would not try a hole-saw larger than 3”. For holes larger than 3” you are better off using a jig saw.
Plastics fall between metal and wood, if the bit will drill metal or wood it will drill plastic.
