Diamond Blades
Q. Is there a diamond blade that will cut everything and do it safely?
A. Yes. To cut all materials safely there is DDIs’ Safety Blade (http://desertdiamondindustries.com/vaccum.php). It is designed with a one-piece steel construction so it will never break during operation, unlike abrasive, carbide and segmented diamond blades. It is designed to cut braces, flat stock, hardened lock shackles, hardened padlock bodies, hockey puck locks, security gates, re-bar, chain link fence, stucco, concrete, block, brick, stone, asphalt, wood, drywall, car doors, ductile Iron, cast iron ,schedule 40 & 80 steel pipe, PVC, HDPE, C-900 plastic pipes, 2x4s, plywood, etc.
Q. Is it better to use an abrasive blade or a diamond blade?
A. Always use a diamond blade whenever possible. Desert Diamond Industries diamond blades will outlast minimum 100 abrasive blades, will not explode during operation, produce less sparks, and lower costs.
Q. Do I need to use water with all Diamond Blades?
A. No. Not all diamond tools require water feed. If a blade is specified to run wet you must feed water to it or you can destroy the blade and the saw. On the other hand, if a blade is specified dry then you can run it wet, this will decrease dust, heat, and increase speed and life.
Q. How safe is a diamond saw blade?
A. Based on OSHA statistics an employee is 6.3 times more likely to be killed and 13 times more likely to be seriously injured requiring hospitalization by an abrasive blade shattering than a diamond blade. Nonetheless, care must be taken anytime you operate a piece of equipment as serious injury or death may occur.
Q. My saw blade is not cutting, is it defective?
A. First, check to make sure the blade isn’t worn out, if so, replace it. Second, if the blade is still good but not cutting it means it’s glazed over. Run the blade through an abrasive material (i.e. asphalt, masonry block, sandstone or dressing stick); this will expose the diamonds underneath. If the blade glazes over again during use, the bond of the blade is too hard for the material being cut. Simply dress the blade again by passing the blade through the abrasive material to expose more diamonds.
Q. Where can I find a dressing stick?
A. Dressing sticks can be found at construction equipment stores that sell diamond saw blades, otherwise you make a few cuts in an abrasive material such as asphalt or cinder block.
Q. What is the bond of a Diamond Blade?
A. The bond is the combination of metals used to make up a diamond impregnated segment.
Q. Can you change the bond of the diamond segment to make it cut faster or last longer?
A. Yes. The speed and the life of the blade depend on having the correct bond for the material being cut. If you are cutting an abrasive material such as asphalt, block or sandstone, the bond will be made of harder metals. For more dense materials like concrete, stone and brick the bond will be made with softer metals.
Q. Does it matter which way the blade spins?
A. Yes. Always mount your saw blade so it spins in the direction of the directional arrows engraved in the saw blade
Q. If I run my saw blade backwards on accident will it ruin my blade?
A. Not necessarily, as long as the blade hasn’t been cracked, chipped or warped it should still be good
Q. The directional arrows on my used saw blade are worn off, how can I tell which way to mount it?
A. The easiest way to do this is to slowly run your finger back and forth on the cutting segment; which ever direction feels the roughest is the direction the blade needs to be spinning.
Q. What is the arbor size of my 14’’ handheld gas saw?
A. It depends on if you own a Stihl saw or another name brand. Stihl saws require blades with a 20mm arbor hole. All other hand held saws on the market require blades with 1’’ arbor holes.
Q. Why is the hole in the center of my blade too small for my handheld saw?
A. It might be because the blade you have has been made with a true 20mm arbor hole. Check the saw blade and make sure there isn’t a bushing in the center of the blade reducing it to 20mm. If there is no bushing contact your blade supplier and exchange it with a blade with a 1’’ arbor hole.
Q. Why is my root cutter blade rubbing the blade guard on my Stihl saw?
A. If you are using a carbide root cutting blade on a Stihl saw the blade will rub because the carbide teeth make the blade larger than 14’’. Contact your supplier for a refund or if you are using a 14’’ blade, exchange the blade for a 12’’ and it should run without rubbing.
