How do you know which Circular Saw Blade is the right one for your job?

4 BASIC BLADE TYPES

FTG BLADES

• FTG Blades Have Teeth Whose Top Edges Are Square To The Saw Plate

• Also Called Rakers, These Teeth Attack The Wood Like A Chisel Chopping

• Fast Cutting And Durable

• Don’t Produce A Clean Surface

• Designed To Rip, Sawing Perpendicular To The Grain

ATB BLADES

• ATB Blades Are Angled Across The Top Edge, With Every Other Tooth “Leaning” In The Opposite Direction

• The Shape Of The Tooth Causes It To Shear The Wood Fibers Cleanly In A Slicing Motion

• The Steeper The Bevel Angle, The Cleaner The Teeth Cut, But The Quicker They Dull

• Marketed As “All-Purpose”

COMBINATION BLADES

• Combination Blades Consist Of 50 Teeth Arranged In Sets Of Five

• Four ATB Teeth Are Followed By A Raker Tooth (ATBR Designation)

• ATB Teeth Are Designed To Crosscut Cleanly While The Raker Teeth Aid In Ripping

• Also Considered “All-Purpose”

TCG BLADES

• The Teeth On A TCG Blade Alternate Between A Raker Tooth And A Chamfered Tooth

• The Chamfered Tooth Roughs Out The Cut, While The Following FTG Tooth Cleans It Up

• Meant For Sawing Dense Materials: Plastic Laminate, Solid Surface Materials Like Corian, And Nonferrous Metals Like Brass And Aluminum

  • FTG:    Flat Top Grind
  • ATB:    Alternate Top Bevel
  • ATBR:  Alternate Top Bevel With Raker
  • TCG:    Triple-Chip Grind
