STUDBUSTERS® can safely and effectively remove studs and bolts of all shapes, sizes and metal types.

STUDBUSTERS employs state-of-the-art technology through its metal disintegration machines (MDM) – the most powerful units available today in the world. Our metal disintegration technology can completely remove a stud, 3 inches in diameter and 5 ½ inches deep, in less than two and a half hours, with absolutely no damage to the female threads in the tapped hole.

How it Works
The MDM technology uses graphite, moly copper or aluminum, depending on the type of burn required, to become a high energy, low voltage, thermal shock-producing source. The electrode in the machine vibrates up and down at a rate of 3,600 times per minute. Each time the electrode touches the piece to be burned, an arc is struck. The arc has a temperature at point of contact of approximately 5,300 ° F. A constant supply of fresh water is pumped down through the electrode causing the molten metal to thermally break down and, at the same time, flushes the thermally shocked metal back out the discharge hole. The discharged pieces are normally less than 10 microns in size – smaller than a grain of sand. The water also acts as a heat exchanger; the only portion to get hot is the small area in contact with the tip of the electrode, unlike drilling where heat from the bit transfers to the matted portion. The MDM maintains everything at ambient temperature, except what needs to be removed.

Key Features
› Removes any size, and burns any configuration, from 40 thousandths of an inch to 5 inches in diameter, in one pass
› Larger studs or holes can be made using multiple passes
› MDM is 40% faster than conventional drilling on average
› Easily removes glazed or hardened studs and bolts
