How to Remove Studs With Drill Bits

Studs stuck in place by rust and paint often refuse to move with hand tools. Any movement is often the stud breaking off below a nut threaded onto the stud. Removing a stud from its housing with drill bits serves two purposes. The first is to heat the stud while drilling, which breaks the bond between the stud and the threaded part. The second is that if the stud wont break free with the heat from the drill bit, the bit will remove the material from the stud until nothing remains in the hole. Using the correct drill bits will often reverse the stud from the part without extraction tools.

Instructions

1

Align the tip of a center punch with the center of the stud. Strike the punch with a hammer. Move the center punch. Repeat the procedure until you have a depression on the center of the stud.

2

Secure the smallest drill bit from a left-handed drill-bit set into a drill motor. Coat the drill bit with cutting fluid.

3

Set the tip of the drill bit on the center-punch depression. Pump the trigger of the drill to drill a hole through the center of the stud.

4

Increase the size of the drill bit in the drill motor. Coat the drill bit with cutting fluid. Pour cutting fluid down the drilled hole in the stud. Drill through the stud with the larger drill bit, using the previous hole as a guide.

5

Swap drill bits until the stud works free of the threaded hole or you can see the threads of the hole sticking through the remaining metal of the stud.
