Diamond Hot-press Saw Blade
1. Manufacturing characteristics
The diamond hot-press saw blade is made by cold-pressing the diamond powder of segment  with the steel blank and then go through hot-press procedure it in the furnace. This production process is particularly suitable for the manufacture of bulk order for same size small saw blades.
2. Specification
    The common diamond hot-press saw blade in the market covers turbo blade, dry cutting blade and continuous blade ranging from ¢105-400mm. The common size is ¢115,125,180,230mm. Regular size of diamond hot-press blade as below :

PS: The thickness mark inside ( ) in continuous blade refer to the thickness of blade for ceramic. The thickness of ¢250,300 blade is 2.0, 2.2mm.
3. Application:
 Hot-press diamond saw blades are widely used in precision processing, decoration, construction projects and others.
(1)Regular Blade:
 Application:  Stone(granite, marble, limestone, travertine), Brick (masonry, tile, ceramic), terrazzo,reinforced concrete, green concrete, asphalt. Turbo blades are especially suitable for cured concrete, hard concrete which anti-pressure >30N/mm², hard brick which anti-pressure around 17-30N/mm².
(2)Hot-press Blade for Ceramic
Application: Masonry, tile quarry tile, porcelain, ceramic,antique bricks, vitrified tiles, glazed tiles, terrazzo, clay roofing. Chipping will be small after cutting. It is recommended to be wet cut; it can also be used for precision cutting of stone.
 Not applicable for glass, reinforced concrete.
(3)Hot-press Blade for Glass
     Application: Various hardness glass and jade with small collapse and fine incision; must be wet cut; can also be used for wet precise cutting of stone etc.
(4)Hot-press special blades for high abrasive material
Application: wall groove, concrete, hard brick, engineering brick, asphalt, sandstone, heavy refractory brick, etc., can be dry cut;
Not applicable for stone, bricks, reinforced concrete, glass, porcelain.
4. Matched Machine
Hand-held cutting machine (masonry saw, tile saw, angle grinder), circular hand saw, stone saw, multi-blades tile saw. Refer to Table 2. for cutting machine power and speed selection.
Table 2.Power/R.P.M for Hot-press Blade
Diameter (mm) Power (kw) R.P.M Max.Cutting Depth (mm)
¢105、115 0.7~1.2 13000 25、32
¢125 0.7~1.2 11000 38
¢150 1.0~1.6 9300(10000) 45
¢180 1.4~2.0 8500 60
¢200、230 1.8~2.4 6600 70、80
5. Requirements:
The appearance of the saw blade: the base and the tip of the cutter must be small and no deformation is allowed; the saw blade has a large rigidity and cannot be soft; the roundness and concentricity of the segment are high; the segment should be sharp.
Quality of blade: smooth, brisk, sharp, not get stuck after cutting; the segments should be firm, strong, trimming edge should be neat and not collapsed;
Note: Read the instructions carefully:; Take preventive measures: 
The cutting machine must be equipped with a protective cover, the assembly should be firm and correct, No bump, impact or lateral force is allowed while cutting. No curve cutting or grinding , wet cut are always more preferable.
