Frequency Asked Question

What’s the difference between electroplated and vacuum brazed?
Electroplated diamond tools have a single layer of diamond on the tools, once the layer of diamond is worn down, the tool is used up and it is time to purchase a new one. But it’s sharpness enough for marble, ceramic, soft tile and so on. It needs water when using it, on some place cannot reach the water, so it’s not convenience for all customers.
Vacuum brazed diamond tools use the special metal bonding and under the vacuum environment make the diamond brazed on the tools, so it will be more fastness than the electroplated tools. More important, you can use it dry, for to work work at the bad environment. It is high efficiency, you can use it in much higher RPM and the work life is also longer than the electroplated tools. Vacuum brazed diamond tools are highly recommented for carvers.

What mean diamond resin bond?
The bond serves two important functions. First, is that it holds or contains the diamond grit in place for the crystal to be able to cut, grind, shape or polish. Second, the bond needs to progressively wear in order to expose new, unused crystals to the surface. Working materials can range greatly in hardness and abrasiveness. The rate of diamond exposure is dependent on the density, type of bond and the working material. Paring the correct bond with the working material is critical for performance and tool life. Resin bonded diamond wheels or resin polishing pads are made by mixing diamond grit with various formulations of resin powders to produce a solid homogenous, multi-layered bond commonly used for very light grinding and polishing.

What mean sintered diamond tool?
Precision sintered (metal bonded) diamond tools are for a large variety of applications, materials, and industries. Metal bonded diamond tools are “impregnated” with diamonds. This means that selected diamonds are mixed and sintered with specific metal alloys to achieve the best cutting performance possible on any materials such as sapphire, advanced ceramics, optics, glass, granite, tile and etc. The metal bond surrounding the diamonds must wear away with a dressing bar to continuously keep re-exposing the diamonds for the diamond tool to continue cutting. Sintered (metal bonded) diamond tools are recommended for machining hard materials from 5 to 9.5 on mohs scale of hardness. Sintered wheels will significantly outlast diamond plated ones.

How many holes i can drill with a diamond core drill bit?
The most common question that is also the toughest question to answer. I wish there was one answer for everybody, but there isn’t. A lot of customers are using diamond bits for the first time. The sea glass hobbyist, the bathroom remodeler and everybody else all ask. The answer depends on how they're going to be used, what's being drilled, electroplated, vacuum brazed, sintered and under what conditions. Next factor how hard is the stone, how thick and what kind of machine you using. So, i can't tell you how many holes, but try to use those tips and you will get the most out of your tool. With small core dril bits between 1-3mm is it dangerous that the core stick in hole from the drill and he will break or damage immently. Mean you have the break out the core after a wile when you drill thicker materials. In this case is it not recommented to use sintered drills for small holes, a vacuum brazed drill is good enough and also cheaper. If you have no water swivel, then use a little plastic container with water and drill the stone direct in the water. Do not force the tool, feel it and let it grind by him self, also you need to use the recommended RPM for your tool size.

How to use hard pressed wool polishing burs?
If you are new in polishing stones then you will made the mistake to use the wool polishing tool right away when you put diamond agent on it. Thats a waste of money, diamond agent will fly away quick. First of all you need for every grit your own polisher, second for to get a good polishing tool, you need to take a little plastic zip bag and you put your tool or tool's included the diamond agent for 24 hours in the bag. The polishing tool will sucks the diamond agent and you have a perfect long time polisher. Note: Mark every zip bag with the diamond grit you use.
