Tool usage:

Carbide rotary file (tungsten steel grinding head) is widely used in mold processing and manufacturing, chamfering, rounding and groove processing of mechanical parts, and trimming of casting, forging and welding parts

Burrs and welds, finishing of pipes and impeller runner, arts and crafts carving of metal boxes and metal materials (bone, jade, stone).

Difference between double groove and single groove:

The double-groove pattern is cross pattern, which is more suitable for objects with relatively low density. For example, it is used on wood, plastic, aluminum and other materials. Fast chip removal with cross, easy to polish and carve

Block the veins, so it is more suitable to have double grooves on soft objects!

The texture of single groove determines that it is not suitable for processing soft materials, because when cutting soft materials, the chip is easy to block the groove, resulting in the texture depth of the groove

The cutting ability decreases when it becomes shallow, that is, the tool is not fast. Single groove is more suitable for hard materials such as iron, copper and steel.
