SD DOUBLE CUT BALL BURR BITS/CARBIDE ROTARY RASP OEM/ODM SERVICE
The difference between double slot and single slot:
The double groove has a cross pattern, which is suitable for low-density objects. For example: used for wood, plastic, aluminum, etc.! The cross pattern has a fast chip removal speed, and it is not easy to block the pattern when grinding and engraving, so it is more suitable to open a double groove on a soft object!
The texture of the single groove determines that it is not ideal to use softer objects, because when the single groove knife is working and cutting, the broken waste will easily block the groove, resulting in shallower groove texture and reduced cutting ability; this is what we often say, The knife is not fast! Single slot is more suitable for iron, copper, steel and other hard objects.
Carbide rotary file features:
Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, and heat resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500°C. It still has high hardness at 1000°C.
Cemented carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drills, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for cutting resistant Hot steel, stainless steel, high manganese steel, tool steel and other difficult-to-process materials.
1. High hardness (86~93HRA, equivalent to 69~81HRC);
2. Good hot hardness (up to 900~1000℃, keeping 60HRC);
3. Good abrasion resistance.
The cutting speed of cemented carbide tools is 4 to 7 times higher than that of high-speed steel, and the tool life is 5 to 80 times higher. Manufacturing molds, measuring tools, life span is 20-150 times longer than alloy tool steel. It can cut hard materials around 50HRC.
