Tips for Drilling Holes as Newbie

A lot of people would need to drill a hole in something at some point. There are a lot of uses for a drill but this is its prime purpose at the end of the day. In this article we’ll show you some useful tips to drill holes into various materials.

Use the right type of drill bit

Specific bits are designed to be drilled by different materials such as wood, metal, concrete, and masonry. If you were trying to use a bit of wood built to get through a wall, it just wouldn’t fit and you’d ruin your wood bit too.

If you know what material you’re drilling through then make sure you’re using a drill bit built for that task.

Use an inspection tools

To stop digging into electrical cables and water pipes, using anything called a stud-finder. Most injuries in the home are caused by people attempting to dig through a wall without realizing what lies behind it.

It is also a smart idea to find out what is hidden behind a wall before attempting to break it through. There are plenty of those tool forms on the market. Much better to be safe than sorry.

Don’t too much force the drill

Let the drill do the job. When you put too much force on the drill, your bit will potentially work less effectively and you run the risk of breaking your bit.

Start with small bit

Start with a small bit and work your way up to the ideal diameter if you are trying to get the cleanest hole possible. With wood this can take a little longer, but it does result in a much cleaner opening. For metal, beginning with a small bit is always a quicker operation, and working your way up.

Protect Your Eyes

It takes only one small fragment to cause a significant eye injury, so proper eye protection is an absolute must when drilling. Choose safety glasses which wrap around the sides of your face for the best protection.

Dept gauge

Lots of tools have depth gauges included to allow you to drill to a particular depth. If yours is broken or you don’t have one, you can also use the masking tape on the bit to show how deep you want to drill.

Use sacrifice board

If you drill straight through a piece of wood, you can always encounter what’s known as “blow out.” That’s when the bit falls out from the other side, making nasty splinters and chips! It is hazy and dangerous. Prevent it by placing a piece of sacrificial board underneath the piece in which you drill. It will make the hole’s rear end come out much cleaner. It is a safe idea as both hand drills and drill presses are used.

Make sure your bit attach tighty

Don’t just stick the bit in the chuck, make sure it goes right in. A bit that isn’t positioned properly will rotate with a wobble, confuse your work and risk breaking the bit. Bits can also have edges flattened at their base. For a strong grip combine these with the chuck jaws.

Learn to drill straight

This may sound easy but many people unintentionally drill at a slight angle, as they concentrate on pushing through the material the drill bit. Enable the drill and the bit to do the job, and focus on keeping the drill as straight as possible.

Most drills come with a small amount of spirit built in, and if you happen to have one, then make good use of that. If you don’t have a level on your drill then use your hand. The main thing you can do is focus on keeping the drill straight and putting trust in the bit to get through the material.

Drill metal at slow speed

The quicker you spin the bit the hotter they get. And heat easily dulls out bits. In general, drilling through metal using a drill bit for metal with as slow a speed as possible is a good idea. Hard metals such as steel and larger drill bits need even slower velocities. You can drill by 3,000 rpm into most metals with a small twist bit (1/16 in. to 3/16 in.). 350 to 1,000 rpm is recommended for larger twist bits (11/16 in.to 1 in.).

Pilot hole

If you’ve got to drill a wide hole then you can always start with a pilot hole. A pilot hole is essentially a smaller drilled hole in the center which can then act as a reference for a bigger drill bit. It makes drilling a bigger hole much faster, and much more accurate.

People don’t even make use of pilot holes enough. They can really make life much easier and make drilling much simpler

Clamps prevent stitches

Never hold one piece of metal in one hand while attempting to drill the other into it. The metal you drill bit might catch, causing the workpiece to rotate, strike and cut instantly (sharp metal edges slice to the bone!). Please use a minimum of two clamps to tie the workpiece down safely.

Mark the holes clearly

You may have heard of the old saying that you measure twice and cut once when it comes to wood sawing. The same goes for drilling. Make sure you have always clearly marked the holes, and calculated where they need to go. There is no turning back after you put a drill into it.

Use oil when drilling metal

The oil serves as a lubricant and maintains bit and material temperature. Specific types of cutting oil are intended to be used for various processes, but typically any household oil with a good viscosity will do for small projects.

Don’t use dull drill

A dull bit of drilling is no fun. Prevent it by using your bit just for the intended content, and not allowing it to heat up too much. If it smoking, stop! When a bit gets so hot you can literally lose the metal’s hardness and tempering. Do consider investing in a drill sharpener in order to keep the bits running over the years.
