For many DIY people, there would possibly come a time when you will need to drive or drill holes through metal materials. The devices and ways used for doing it are nearly as various as the diverse kinds of metal material out there. The followings are 8 useful tips to make the job faster, easier and safer with best cordless drills 2016.
No Decorative Bit Needed
Almost any basic-purpose twist bit would do a good job of driving or drilling hole into metal. In reality, most devices are produced to drill into a wide range of material such as plastic or wood. The least costly bit of twist is made of high-pace steel, and this basic bit is only suitable for most metal-drilling jobs.
If you will be drilling or driving a lot of holes, or want to drill into abrasive and hard metals such as cast iron or stainless steel, then you should spend some more money for bits made from cobalt steel or black oxide. This bit would drill more holes before it becomes dreary.
Protect The Eyes
It just takes you one small metal piece to cause an extreme eye wound, so appropriate protection for your eyes while drilling metal material is a definite must. For the best cover, remember to choose protective glasses that cover all the sides of your head.
Make a mark
Drill bit has a tendency to stray when you begin to drill. To avoid this, assess and highlight the point that you want to put the hole on and then use a centre hammer a punch to make a tiny mark. This gives the end of the drill bit an area to go in as you start to drill.
Lubricate Bit for Lasting Longer
For drilling or driving hole into steel that is 1/8 inch or denser, remember use a 3-in-one oil like or a cutting fluid. Lubrication for the bits could reduce accumulated and heat resistance, meaning that the process of drilling could be simpler and your bit will last longer. For metals that are easy to drill such as cast iron, aluminum or brass, lubrication is not often usually essential.
Begin with a Tiny Hole
You need a large hole? Begin with small one! Most bits of twist are available with the size up to 2 inches in radius, but you will get the greatest result by beginning with a 1/4 inch hole and then drilling consecutively bigger hole until you achieve your targeted size.
Hole Saws Make Larger Holes
For large and big holes, a hole saw could get the task done quickly and easily. As the twist bit, a hole saw will chuck right through the drill and would cut into thin-gauge metal such as steel or aluminum. As a result, you have to use a bit of plywood as the support for the bit of the hole saw as well as to prevent your working surface from any serious damages.
Drill and Drive at a Slow Pace
The faster a drill bit could spin around, the more heat it would generate. In fact, it is a good idea to driver or drill into metal materials operating as slow a pace as possible. Tough and hard types of metal such as steel and bigger drill bit requires even a slower pace. With a small bit of twist (ranging from 1/16 inch to 3/16 inch), you could drill or drive into most metal surfaces at 3000 revolutions per minute. For bigger bit of twist (ranging from 11/16 inch to 1 inch), 350 to 1000 revolutions per minute is suggested.
