Factors to Consider Before Buying Best Drill Bit
When it comes to drilling out broken bolts, you need to ensure that you have the right equipment and knowledge for your job. You will want to consider a few things in order to get the most from your purchase. Here are a few points about factors to consider before buying the best drill bit for drilling out broken bolts.
Easy To Use
Although you may be shopping for a drill bit to remove damaged screws or bolts in any situation, you still want to find something that is easy to use. You will need to do some research and make sure you have a drill bit that is easy to use in critical situations.

Number of Cutting Sizes
You want to make sure the product has more than one cutting size as well as various styles in order to accommodate a variety of jobs. This will ensure that you have the versatility needed when working with corroded screws and bolts.
Price
As with most products, price is an important factor to consider when making any purchase. Your budget will help dictate which products can be considered for purchase.
Material Compatibility
The wrong material compatibility can leave you with damaged tools and sputtering from the machine. If you need a drill bit to function as a nut extractor, make sure it is compatible with the material.
Number of Flutes
The number of flutes on a drill bit can really determine the quality and performance of your bit. A 6-fluted drill bit is more effective than a single flute at removing snapped screws and bolts.
Speed
You want to strike a balance between speed and precision while also getting as much torque out of the tool as possible. Drill bits with greater speeds are great for larger jobs, but are less precise in their cuts compared to slower drills for removing broken bolts.
Handle Design
Of course, one of the most important things you’ll need to consider is the handle design. A non-slip grip will ensure that your drill stays secure while you are drilling out damaged screws and bolts.
Advantages of Using drill bit for Drilling Out Broken Bolts
Designed for Removing Broken Bolts
One of the advantages of using drill bits is that they are designed for this exact function, to function as a bolt extractor. Other tools are more likely to damage either the nut head or threads. The drill bit generally engages the broken nut in a sideways manner that does not cause further damage to the nut or screw head.
More Accurate than a Hammer
It is much more accurate than using a hammer to try and break the bolt, since it’s so small and has a specific design. It also has a round rim, so it doesn’t leave sharp edges where the screws and bolts are.
New Bolt Threads are Undamaged
Another advantage of using drill bits for removing even the most stubborn broken bolts is that it will not damage the threads of a new bolt as much as other methods. Friction from using a hammer or punch to remove the broken nut can damage the threads on a new screw or nut.
Works Through Metals and Other Hard Surfaces
Drills can be used to make holes in metal and other hard surfaces. Drill bits are designed for removing broken bolts and drill holes in metal are useful for many different things.
Can Cut Through Bolts in a Matter of Seconds
The best thing about drill bits can remove broken bolts in seconds; it does not take very long at all. This is especially true when you use a drill with the drill bits.
FAQs:
What is a Drill Bit?
A drill bit is a cutting tool used to cut through hard, difficult materials.
When to use a Drill Bit for Drilling out Broken Bolts?
Use a drill when:
- If the bolt can be extracted by drilling.
- If there is still a considerable portion of the bolt left inside the hole that can be extracted by drilling.
What Size Drill Bit Should I Use?
Try a small size drill bit first, but don’t drill out to remove broken bolts only what comes out. Drill as much as possible, then go to the next larger size. Start at 1/8 inch and work your way up. If you try to drill only what comes out, chances are the part that is still in there will not come out.
I’ve Never Drilled Out a Broken Bolt Before. Do You Have Any Tips?
Don’t second guess yourself, and use the drill bit to drill as much of the bolt that will come out, then go to a bigger bit. DO NOT BE SWAYED TO DRILL LITTLE BIT BY LITTLE BIT.
If you try to use drill bits to drill only what comes out, chances are the part that is still in there will not come out. What comes out will loosen the rest of the bolt that is still attached to the object, and it will all come out in one big piece.
Can a Drill Bit Take Out Broken Bolts from Cars?
Yes, a drill bit can be used in extracting broken bolts from cars. The removal depends on the size and shape of the bolt. When you have drilled out deep enough into the bolt head, you should be able to loosen the bolt easily with your fingers.
How do I Choose the Correct Size and Shape of Drill Bit to Extract Broken Bolts?
You can easily find the correct size and shape of drill bits to remove a specific type of broken bolt by following these steps:
1) Identify what type of bolt you need to remove. Common types of bolts include carriage bolts, square head bolt, hexagonal bolts, lug nuts and many more.
2) Identify the size and shape of your broken bolt. For example, if you are trying to remove a carriage bolt with a cross-shaped head measuring 1/2 inch in length from the bolt, you need a 1/2-inch cross drill.
