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

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
