Metal-Cutting Carbide Blades
Carbide Grain Structure
SAIT Carbide Matrix
- Consistent size of carbide grains.
- More carbide per tooth as grains are smaller.
- Smaller grain = harder tooth, more durability.
Competitor Carbide Matrix
- Very inconsistent size of carbide grains.
- Less life due to larger grain sizes.
Triple Chip Grind (TCG):
- FEATURE: Maximizes blade life by reducing the size of the metal chips that are produced during the cutting operations. Also provides maximum tooth strength for longer life.
- BENEFIT: Cleaner and cooler cuts and less stress on material being cut.
- WHERE USED: Steelworker® (all sizes), 7-1/4” Stainless, 8”, 10” and 12” Aluminum blades
Alternate Top Bevel (ATB)
- FEATURE: A multi-purpose grind that allows for durable, long life as well as productive work across a wide range of materials.
- BENEFIT: Clean, easy cutting without binding in the material.
- WHERE USED: 6-1/2” and 7-1/4” TMX, and 14” Aluminum Blades
Modified Triple Chip Grind (MTCG):
- FEATURE: Excels at reducing chip size for more effective cutting of material. Also improves cutting tooth durability.
- BENEFIT: Lower heat build-up and less blade stress while cutting.
- WHERE USED: 12” and 14” TMX and 14” Stainless Steel Blades.
Blade Operation Tips
- Be sure to mount the blade with the rotational arrow positioned the same direction as the tool rotates
- Follow circular saw manufacturer's warnings and instruction manual
- Check blade prior to use for any visible cracks, loose or missing teeth, etc. and change blade if found
- Use blade only on recommended material
- Mount blade between designated sides of blade washers matching arbor size and shape
- Always wear ANSI-approved eye protection and proper protective equipment
- Always wear gloves
- Adjust foot-plate of the saw to proper depth (check circular saw manual - 3 teeth exposed below material surface is a common rule of thumb)
- Always work in a clean and unobstructed work environment
- Never operate saw without working blade guard
- Do not use excessive pressure when cutting (this causes the blade to wear prematurely)
- Tighten blade bolt as instructed by saw manufacturer
