The below links offer information on carbide tooth terms, hook angles, and grinds.
Saw Tip Configurations (also Styles or Grinds)
- FLAT TOP (FT) / FLAT TOP GRIND (FTG)
Used on saw blades for cutting soft and hardwood along the grain (ripping).
- ALTERNATE TOP BEVEL (ATB)
Alternate right top bevel and left top bevel. Used on saw blades for general purpose and crosscutting natural wood & veneered plywood.
- ALTERNATE TOP BEVEL MODIFIED (H-ATB)
Higher top bevel grind and longer tooth than our standard alternate top bevel. Used on 'MB' and 'MSB' series blades and specifically designed for cutting melamine chip-free on table saws without the aid of scoring units .Also used on dado sets, only every 6th tooth is flat ground.
- COMBINATION TOOTH (4 & 1)
Groups of four alternate top bevel and one flat ground tooth, divided by large gullets in the saw plate. Used in combination blades for general purpose wood applications.
- TRIPLE CHIP (TCG)
Alternate flat rager tooth and higher trapeze tooth divides the chips to achieve cuts in hard materials, MDF, OSB and plastics. Also used on blades for cutting non-ferrous materials.
- HOOK (RAKE) ANGLE 6° - 22°
Soft materials or rip blades require an angle of about 18° to 22°, hard materials about 6°.Saw blades for cutting aluminum and melamine have a negative hook angle.
- TOP CLEARANCE ANGLE 12 ° - 15 °
This angle changes according to the hardness of material; 12° for hard and 15° for softer materials.
- i. TOP BEVEL ANGLE 6° - 22°
ii. RADIAL SIDE ANGLE 1 ° - 2°
Normally 10°, enabling gradual penetration into material. Allows clearance along the sides of the tooth.
- Rip Blade
A saw with rip teeth meant for cutting a board along its length (with the grain).
- Crosscut Blade
A crosscut blade has teeth oriented in an "alternate-top bevel" (ATB) pattern. Which slice wood fibers like a knife, separating them cleanly.
The shaft, driven by the saw's motor, which turns the saw blade. Also called a mandrel.
