How to Choose the Best Drill Bit for Drilling Out Broken Bolts: The Buying Guide

Choosing guide for Drill Bit for Drilling Out Broken Bolts
How to Choose the Best Drill Bit for Drilling Out Broken Bolts

The most important thing about buying something is knowing about the product’s recommendations. Also buying the best drill bit for drilling out broken bolts have some perimeters that everyone should know before buying the product. Before buying any of the above products let’s check some recommendations to consider the best tool for drilling.

Below few important factors are discussed that you must consider before purchasing a drilling tool.

Durability

In one word we can say a drill bit drilling tool works depending on its durability. The more durability it has, the more pressure it can handle. Suppose you buy a product and after start using it just gets ruined.

At present, if you go to market then you will know materials that are made with Cobalt and Platinum have better durability.

Material of Drill Bit

The material of the drill bits is the most crucial factor you must consider before purchasing. The penetration power of the drill bits mostly depends on the quality of the material of the drill bits.

So, to penetrate the hardened surface smoothly through drilling, you must ensure that the material of the bits is of premium quality.

Power of gripping

Another important thing to check is to find out the power of gripping the broken screw that is stuck inside. However, the length of the screw also depends here. If the power of gripping in the drill is not so high, then it can’t take out every broken screw from the wall.

Any kind of ceramic and thick than a normal wall requires a more powerful gripping tool to pull out the broken screw from the wall. If you want to pull out the broken screw from a ceramic or thick wall the drill has to produce more grip to pull the screw.

Design

Basically, a drill bit extractor is made with two types of designs. One there is a left-handed spiral, and another type is regular. The left-hand spiral design let you finish your job with too much comfortably and safely.

But there is a drawback to using the left-handed spiral drill bit. if you are not left-handed then it will be too much pain for you to handle and finish the work with your left hand. If you are not a left-handed person, then we suggest you must go with the regular design drill bit.

A left-handed spiral looks cool, but it will waste your whole money if you are not able to work with your left hand.

Nature of the work you are purchasing for

Before purchasing a drill bit, you have to decide first which type of work you are going to use it for. This will help you make a better decision in choosing a product with your recommendations.

So, if you want to buy a drill bit to carry out a regular drilling job, not for heavy-duty work, then you must go for the drill which is offered in an affordable price range.  

Additional things

Other things to check before buying a drill bit are to check its holders, holder extension, and additional sleeves. If all these conditions of the drill bit are not so well then you can’t do your job comfortably.

So before buying a drill bit for drilling about the broken balls all these things you have to keep in your consideration. With all these buying guidelines probably, you can choose the best product for your work.

How to Remove broken bolts, studs, and screws

As you are looking for the best drilling bits for drilling out the broken bolts, you must have concrete knowledge about how to remove broken bolts, studs, and screws.

Instructions are organized in 5 steps for your better understanding.

First- Pointing out the center of the head of the broken bolt with a center punch by hammering

This is the very first step of the whole procedure. So, at the very beginning, you must try to locate the middle center of the head of broken bolts as precisely as possible. Then place the center punch at the located middle center point. After placing, hit it squarely. This will create an initial point for drilling a pilot hole.

In terms of locating the middle center point on the head of the bolt, it is crucial to locate it precisely. Lack of precision in locating the middle center may result in damage to the threads while drilling the pilot hole. If the thread is damaged, it will become impossible to insert a new bolt there.

Second- Slowly create the pilot hole using a left-handed drill bit

For this step, you must need a left-handed drilling bit to make a pilot hole. These left-handed drill bits are known as “reverse drill bits” which rotate counterclockwise. This is a warning, don’t pick the traditional right-handed drill bits.

Now, place the left-handed drill bit at the center of the head of the bolt where you have already made an initial point. Run the drill machine as slowly as possible, 20 rpm is mostly recommended. Create a pilot hole with an approximate dept of ¼ inch. It may take time to create the pilot hole in the bolt, but you must perform it carefully with proper gripping power to avoid any damage to the thread.

The interesting fact in this step is that the left-handed drilling bit, rotating counterclockwise, will not tighten the bolt while drilling. Instead, it will loosen the bolt a little bit as the drill is rotating counterclockwise.

Third- Placing an extraction drilling bit in the pilot hole

After the creation of the pilot hole, this step requires placing an extraction drilling bit in the pilot hole. This time, you will also need a left-handed drilling machine inserted with an extraction drilling bit.

In this step, you will also require reverse drilling of the extraction bit which also rotates counterclockwise as well. Now, gently place the extraction drilling bit inserted drilling machine in the pilot hole.

Fourth- Running the reverse extraction drilling bit machine slowly

In this step, you also require maximum concentration. Once you have placed the extraction drilling bit perfectly in the pilot hole, then run the drilling machine slowly. Like the previous stage, 20 rpm is recommended.

Once the extraction bit grabs the bolt perfectly, slow and steady becomes the main key then. Maintain your slowness and steadiness until the bolt becomes extracted from the hole entirely. Lack of steadiness may the breaking of the bolt which will require a more challenging extraction process.

Fifth- Removal of any metal shaving left behind after the extraction

There is a strong possibility remains that any metal shaving may be left behind in the hole after the extraction. Removing those metal shaving is necessary, otherwise; they may create obstacles while inserting a new bolt.

For this step, you will require a small magnet that will fit in the hole. Now, insert one side of the magnet in the hole while another side is held by you. If there is any metal shavings are left behind after extraction, they will get attached to the body of the magnet. Like this process, you must clear all the metal shavings from the hole.
