To improve safety, fuel economy and vehicle performance, a number of high strength steels are used in manufacturing General Motors vehicles.

These various high strength steels and their location in specific vehicles can be found in Service Information | Body Repair | Collision Repair |

Visual Identification.

To perform structural or collision damage repairs, it is often necessary to drill out (remove) resistance spot welds in order to separate the

components being serviced from the vehicle structure.

A variety of drill bits are available to remove these resistance spot welds, however the useful life of many of these drills is limited by the hardness

of the high strength steels.

The General Motors Collision Repair Technology Center has recently validated a *CryoCobalt(TM) drill bit that has been developed for use with

very hard metals. These drill bits performed with exceptional results and should allow for increased production and reduced overall cost related to

resistance spot weld removal. These drill bits can also be re-sharpened.

These drill bits are available directly from the manufacturer. Refer to the ordering information below.
