The tooth design of scoring saw wood circular saw blades
is a critical aspect of their performance. It directly impacts the quality of the cut, chip prevention, and overall blade durability. Here are the key characteristics of the tooth design for scoring saw blades:
Close Tooth Spacing: Scoring saw blades typically have a high tooth count, with teeth closely spaced along the circumference of the blade. This design allows for a fine, precise cut on the surface of the material.
Alternate Top Bevel (ATB): Many scoring blades feature an alternate top bevel tooth configuration. This means that the teeth have alternating bevels on the top edges. This design helps in reducing tear-out and splintering by creating a clean slicing action.
Negative Hook Angle: Scoring blades often have a negative hook angle, meaning the teeth are angled backward or downward in relation to the direction of rotation. This negative hook angle minimizes aggressive cutting and helps in achieving a scoring action rather than a deep cutting action. It's important for scoring blades to avoid grabbing and lifting the material.
Flat-Top Teeth: Some scoring blades have flat-top teeth with no bevel or chamfer on the tips. These flat-top teeth can provide an exceptionally clean cut surface with minimal chipping or splintering.
Carbide Tips: To enhance durability and longevity, scoring blade teeth are often equipped with carbide tips. Carbide is a hard and wear-resistant material that can withstand the abrasion encountered during cutting, ensuring a longer blade life.
Alternate Shoulder Grind (ASG): In some cases, scoring blades may feature an alternate shoulder grind tooth design. This design helps in reducing the impact of the blade on the material, contributing to a smoother scoring action.
Precision Ground Teeth: Scoring blade teeth are precision ground to ensure consistency and accuracy in their shape and sharpness. This precision is crucial for achieving clean, chip-free cuts on the material's surface.
Gullet Shape: The gullets are the spaces between the teeth on the blade. In scoring blades, the gullets are often designed to be smaller compared to those on regular cutting blades. This reduced gullet size minimizes the amount of material removed with each tooth engagement, contributing to the shallow scoring action.
Anti-Kickback Design: Some scoring blades incorporate an anti-kickback design, which helps prevent the blade from grabbing the material and kicking it back towards the operator. This enhances safety during operation.
Adjustable Scoring Width: Many scoring blades allow for adjustment of the scoring width, which is the depth of the groove or kerf created on the material's surface. This adjustability allows users to fine-tune the blade for different materials and cutting requirements.
In summary, the tooth design of scoring saw wood circular saw blades is engineered to achieve clean, precise, and shallow cuts on the surface of materials like wood, plywood, and laminates. The combination of tooth configuration, carbide tips, and other design elements ensures that scoring blades effectively reduce chip-out and splintering while providing long-lasting performance.ZCDJ-011 Stainless Steel Working Circular TCT Blade
