Diamond mining core drill bit and methods of making thereof
A core drill bit includes an elongate hollow cylindrical body having opposite first and second end sections, a plurality of cutting segments with a connecting portion joined to the second end section, a plurality of reinforcing members joined to the second end section between the cutting segments and contacting adjacent cutting segments to offer rotational support thereto, and a plurality of current concentrators disposed on one or both of the second end section and the connecting portion. The cutting segments being capacitive discharge welded to the second end section whereby the surface of the second end section melts during the welding to affix the cutting segments with the tool body.

Cylinder bore coating system
Embodiments of the present innovation relate to a cylinder bore coating system which simultaneously combines both friction and wear properties to enhance engine efficiency and operating life. The cylinder bore coating system includes a relatively thin top layer, such as diamond like carbon layer (dlc), disposed over a thicker, relatively hard and high modulus coating (i.e., an under coating).
