THE DIFFERENCE BETWEEN U DRILL BIT AND ORDINARY DRILL BIT

U Drill Bit, also called quick drill, is a kind of internal cooling drill bit, which has good cutting and high efficiency, and can drill continuously. The front end of the cutter body is equipped with a replaceable blade, which reduces the cost of use. The difference between U-drill and ordinary drill is that U-drill uses blades----peripheral blade and center blade. After the tool is worn, it can be replaced directly without regrinding. The use of indexable blades saves material than solid hard drills, and the blades Consistency makes it easier to control part size. The rigidity of the U drill is good, and a high feed rate can be used, and the processing diameter of the U drill is much larger than that of the ordinary drill, and the maximum can reach D50~60mm

　　The main features of the drill bit:

　　The minimum diameter can reach 10mmX3 times the length

　　Double-angled inserts for greatly increased feed

　　The center edge and outer edge use the same blade, easy inventory management, and low cost

　　Higher precision, better surface finish

　　Unique tool position design makes cutting more labor-saving

　　More suitable for various special processing

　　During drilling, maintain good drilling straightness

　　Ensures correct positioning of drilled holes

　　To improve the quality of irregular drilling exits, the main materials are high-speed steel; powder metallurgy; cemented carbide.

　　A drill (zuàntóu) is a tool used to drill through holes or blind holes in solid materials and to ream existing holes. Commonly used drills are twist drills, flat drills, center drills, deep hole drills, and nesting drills. Although reamers and countersinks cannot drill holes in solid materials, they are customarily classified as drill bits.
