Question : Which way do I install the blade on my tool?
Answer : The blade direction is printed on the front of the blade. Install the blade so that the blade will follow this direction. If the front of the blade is no longer legible, a directional arrow is embossed into the back of the blade. As a last resort, examine the diamonds. The bond tail behind each diamond should be pointing the opposite direction of blade rotation. If the blade is installed incorrectly, the bond tails will reverse direction, which may cause some premature wear.
Question : What materials can I cut with the Alpha® Numero Uno blade?
Answer : The Numero Uno wet blade series is primarily designed for granite, marble and engineered stone slabs or tiles. The Numero Uno 4-1/2” and 5” blades are designed for porcelain and ceramic tiles, which can be used in either wet or dry cutting applications.
Question : Can I cut Onyx with the Alpha® Numero Uno blade?
Answer : No. We don’t recommend cutting Onyx using our Numero Uno blades due to the aggressive cutting action, diamond grit size and turbo rim style of these blades. We recommend the Alpha® Vetro blade designed for the glass application for cutting Onyx. It has a continuous rim with finer diamonds to minimize the chipping of the edge.
Question : Can I use the Alpha® Numero Uno blade for dry applications?
Answer : Yes and No. The Numero Uno 4-1/2” and 5” blade can be used either wet or dry, since the diamond matrix is designed for use on hand power tools such as our Alpha® AWS-110 or AWS-125 and high-speed angle grinders. However, the larger Numero Uno blades must be used in wet at all times.
Question : The speed of my cut is slowing down. What can I do to improve it?
Answer : The diamonds are rounding over or glazing causing the blade to loose its cutting ability. You need to re-dress the blade using a soft abrasive material such as a dressing stone or a concrete block.
Question : What is the maximum RPM at which I can use the Alpha® Numero Uno blades?

Question : What is the arbor size of the Numero Uno blades?
