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 :

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.
6. Performance (for reference only):

hot press saw blade coefficient
| Blade level | Saw blade shape | Specifications | Efficiency (coefficient) | Life (coefficient) |
| Excellent grade |
Fine tooth turbo saw blade | ￠105～130 | ≥4 cm2/sec （1） (=1.2m/min) |
≥2 m2/mm （1） (=100m/mm) |
| ￠150～230 | ≥4.8 cm2/sec （1.2） | ≥2.8 m2/mm （1.4） | ||
| Segmented saw blade | ￠105～130 | ≥3.6 cm2/sec （0.9） | ≥2.4 m2/mm （1.2） | |
| Continues saw blade | ￠105～130 | ≥3.2cm2/sec （0.8） | ≥2.8m2/mm （1.4） | |
| Note: 1. The cutting machine parameters sets according to Table 2; 2. The stone sample: thickness is 20mm, medium hard granite, such as 635; 3. The coefficient in parentheses is based on the superior-grade Dia105～130 Fine-toothed turbo saw blade; 4. All testing goes on with the same shape and the same specification blades , the standard saw blade coefficient with: efficiency 0.85, life expectancy 0.85; economic saw blade coefficient with efficiency 0.6, life expectancy 0.7. |
