Metal drilling can be really very smooth if you know few techniques and procedures for drilling. Many people often end up making improper hole due to poor technique or lack of proper drilling experience. Therefore, little information provided in this write up can be very handy for anyone who is interested to do DIY project. Following few tips can help you to avoid few common mistakes that many people often do due to lack of any experience.
Metals are little harder material and therefore you need to hold your drilling machine with both the hands. However, while drilling holes you need to make sure that your metal piece is held securely. Therefore, you must use a vise so that your metal does not shift its position while drilling. If you do not have vise then you need to make some arrangement to fix the metal piece securely or get some support from Nutty DIY.
Your hole will be drilled in the accurate position, if you mark a hole and punch it before using your drill machine. Drill will not slip from its position then. It is not necessary that the punched hole must be too large however it should be big enough to hold the tip of your drill bit. This hole will act as a guide to make a straight hole.
It is essential that in the beginning you must start by drilling slowly so that you can mark the position properly. You also need to keep your hand steady during this time. Metal being a hard material can always buckle and hence proper control is necessary. Therefore, you should never exceed medium speed while drilling. Slow drilling is much safer so that you may not drift away from the right position.
If you select the right kind of drill bit then your job will become much easier. If the metal is soft then use cone drill bit or step drill bit, so that you will get best result. This will also help you to drill of different diameter. Initially start with thin bit and then drill with larger bit.
It is better to use High Speed Steel (HSS) drill bit while drilling holes on metal surface as they are much more powerful and stronger. However, for aluminum you must not use such drill bits as it is softer material. If you need to drill on heavier metal then use cobalt bit, which is stronger than HSS bit. Carbide bits are the hardest one.
Metal drilling may often lead to minor accident particularly if you are handling your drill machine for the first time. Therefore, while drilling you must use safety goggles so that no metal particle may enter into your eyes while drilling. Ordinary spectacles are usually not good enough in such cases. You must also wear proper hand gloves to protect your hand. However, while drilling on softer material or drilling smaller holes it may not be necessary.2017-12-26
