Alternate with Raker ‐ AR 4+1
Similar configuration to ATB, but every fifth (5th) tooth (for 4+1 configuration) is a raker (square shoulder, no top bevel). This raker helps keep the sawblade "straight" during the cutting process. This design can be used for rip cutting and cross cutting in a variety of hard woods, soft woods, plywood and chipboard. This design can be produced in a 2+1 configuration if required by the number of teeth on the sawblade (48 teeth for example).
Does NOT cut a Flat Bottom as this configuration creates "cat ears" or "bat ears" at each corner of the groove.
