Circular Saw Blade: 355×25.4×3.2x120T
Specifications
Based on standard engineering nomenclature, here is what each number corresponds to:
| Specification | Value | Additional Details |
| Diameter | 355 mm | Equivalent to 14 inches in standard imperial measurement. |
| Bore (Arbor Hole) | 25.4 mm | Standard bore size, equivalent to 1 inch. |
| Body Thickness | 3.2 mm | A relatively thick blade body designed for enhanced rigidity. |
| Teeth Count | 120T | A high tooth count optimized for extremely fine and smooth cuts. |
| Tip Material | TCT (Tungsten Carbide Tipped) | Utilizes Tungsten Carbide, a highly durable material for superior cutting performance and longevity. |
| Tooth Grind | Recommended: TCG (Triple Chip Grind) | For a 120-tooth blade, the TCG profile is typically recommended for optimal aluminum cutting. |
Target Application & Uses
Primary Application:
This saw blade is engineered primarily for cutting aluminum and other non-ferrous metals, specifically targeting applications requiring high precision and superior surface finish:
-
Aluminum Profiles: Such as window frames, door frames, and architectural aluminum extrusions.
-
Aluminum Plate: Suitable for thicknesses ranging from 1/8 inch to 1/4 inch, or slightly thicker.
-
Aluminum Tubes
-
Other Non-Ferrous Metals: Including copper and brass.
Important Note Regarding Wood Applications:
-
A 120-tooth circular saw blade is strictly not recommended for standard wood cross-cutting applications. The excessive number of teeth can generate significant heat, leading to wood scorching and a high risk of kickback. This blade is intended for specialized material applications, not general woodworking.
Usage Recommendations
-
Cooling and Lubrication: When cutting aluminum alloys, employ cutting fluid or lubricant (e.g., aluminum cutting spray) to prevent material buildup on the teeth and to manage heat generation.
-
Spindle Speed (RPM): Ensure the cutting machine is equipped with an appropriate spindle speed (RPM) calibrated for metal cutting blades. Generally, aluminum cutting requires a variable speed machine for optimal safety and performance. Do not use high-speed woodworking saws for metal cutting.
-
Workpiece Clamping: Securely fasten the aluminum workpiece to the machine’s base to prevent vibration and workpiece movement during the cut.
-
Material Thickness: This 120-tooth blade is optimized for medium-thickness aluminum. For very thin materials, a blade with more teeth may be advantageous. For significantly thicker materials, consider a blade with fewer teeth to improve chip evacuation.
