Rotary burrs are made of tungsten carbide, which is sharp and durable. And the hardness can reach HRC70. The durability of carbide bur is 10 times that of high speed steel cutter (HSS cutter). 200 times more than the durability of the small wheel. Comprehensive processing costs can be reduced about 10 times.

【Double Cut or Single Cut】 Double cut burrs have more cutting edges and can remove material much faster. It is more suitable for relatively low density materials such as wood, plastic, aluminum, mild steel and all non-metallic materials. The single cut end mill provides large, wide flutes to evacuate large chips with ease and also prevents iron shavings from accumulating and overheating from causing damage to the cutter head. It is more suitable for relatively high density materials such as iron, alloy steel, stainless steel, etc.

【20-Piece Professional Set】Carving bits include burr types A, C, D, E, F, G, H, L, M and N. There are 2 sizes for each type of burrs, which are 1/8 shank and 1/8 head diameter and 1/8 stem and 1/4 head diameter. They are suitable for almost everything you need to engrave, cut, shape, grind, polish and remove sharp edges.

【Easy to use】If the cutting bits chip easily, it could be because the speed is too slow. However, it is ideal to start cutting slowly, increasing speed as you go. High speeds will prevent the flutes of your burs from clogging. 1/8 milling cutters can support the speed range of 6000-50000 revolutions per minute.

【Widely Used】The 3mm 6mm head diameter carbide end mill set is widely used for metalworking, tool making, model engineering, wood carving, jewelry making, welding, chamfering, casting, deburring, grinding, butt port and carving.
