Standard teeth quickly remove excess material from most materials and achieve good workpiece accuracy
Crossed teeth are more conducive to chip breakage. When processing welded parts or other hard materials, only small or fine wire like chips are produced
Coarse teeth can quickly remove excess of soft materials such as non-ferrous metals and non-metals
Fine and dense teeth can be used in situations with high quality requirements and less removal allowanceThe rotary file offers four tooth shapes – standard teeth, cross teeth, coarse and sparse teeth, and fine and dense teeth, with cross teeth also providing fine and dense cross teeth
