diamond blade terminology cut through industry terminology - specify the correct blade to match your application narrow gullets continuous turbo rim cooling holes conical segments 30 degree gullets key hole gullets turbo segmented deep draft segments wide gullet inclined wedge segment reinforced flange If a diamond blade has narrow gullets there will be less chipping of material and a slight reduction in vibration. If a diamond blade has a continuous turbo rim then there will be less chipping than with segmented blades and faster cutting due to the castellation of the rim. This clears debris quicker and keeps the blade cool by trapping air in motion. Cooling holes in a blade as the description says, will keep the steel core cool and will prevent distortion of that core. keeping the diamond matrix cool in segments will improve speed and life. Conical segments will lower vibration thanks to the consistent gap between the segments. There will be an increase in product life thanks to the greater size of the segment and a decrease in noise due to there being less air distortion in motion. In line, 30 degree gullets help clear debris faster and they improve life as a result. Similar to narrow gullets, key-hole gullets result in less chipping of the material being cut and a reduction in vibration levels. Similar to continuous turbo rims, there is less chipping of the material and faster cutting thanks to the castellation of the segment. The debris is cleared quicker and the blade is kept cooler. Deep draft segments give the diamond blade undercut protection, whilst cutting in abrasive materials such as asphalt or abrasive stone. Wide gullets clear debris faster when cutting through abrasive materials. Inclined wedge segments give the diamond blade undercut protection, whilst cutting in abrasive materials such as asphalt or abrasive stone. A reinforced flange gives the diamond blade more stability under extreme use and keeps the steel core in line, therefore giving a cleaner, straighter cut. MICRO segments Using 25mm micro segments reduces the contact area with the material and therefore increases cutting speed. The increased number of gullets also improves the clearance of debris, extending the life of the blade.
