Why the Diamond Segment of Diamond Blades Can Break Off

June 13th, 2011

A common problem diamond blade users may encounter is that one (or more) diamond segment break off the diamond blade. This problem is often known as segment loss, which not only means the damage of the diamond blade, but may cause serious security issues because of the segment flying out.

Advantages of Laser Welded Diamond Core Drill Bits

December 18th, 2010

There are mainly two kinds of diamond core drill bits: laser welded ones and silver brazed ones.

For silver brazed diamond core bits, their diamond segments are brazed onto the steel tube of the core bit with silver solder. Comparing with laser welded diamond core bits, their production technology is simpler and they are cheaper, but the bonding strength between their diamond segments and their steel tube is lower, and they cannot be used in dry drilling, because if the temperature generated in the drilling process exceeds 600°C, the silver solder may melt and then the diamond segments may fall off the steel tube. Water should always be used to cool the silver brazed core bits when drilling.

Types of Saw Blades

October 19th, 2010

Perhaps the often sighted saw blade is a long steel plate with many saw teeth on one side to saw wood. Actually, besides this traditional woodworking saw blades, there are wide categories of saw blades for various uses. Just say the saw blades’ shape, the base of a saw blade can be a long steel plate, a circular blade, a closed steel band, a thin wire, or of other shapes. The blade’s teeth are often designed to have many styles to fit the needs of cutting different types of objects. Saw blades can also have no teeth but have just a continuous cutting edge.

Wholly Sintered, Silver Brazed and Laser Welded Diamond Saw Blades

June 12th, 2010

Perhaps the most commonly sighted diamond circular saw blades are the sintered metal-bonded ones, on which diamonds are mixed and sintered with metal bond materials to form the blades’ cutting edge — diamond segment. Normally, these blades are made via 3 methods: wholly sintering, silver brazing and laser welding. The diamond blades made via these 3 methods are different and have their respective features and applications.
