Description

Technical Field

[0001] The utility model relates to the technical field of hole drilling, in particular to a novel diamond hole drill. Background Art

[0002] The drill bit used as the cutting edge is called a diamond drill bit. This one-piece drill bit, with no moving parts and a relatively simple structure, offers high strength, high wear resistance, and high impact resistance. It was one of the three major drilling technologies introduced in the 1980s. Field use has proven that diamond drill bits offer advantages in drilling soft to medium-hard formations, including high speed, high footage, long life, stable operation, few downhole accidents, and excellent wellbore quality. Diamond drill bits not only have a long service life but are also reusable. Repaired diamond drill bits perform similarly to factory-repaired diamond drill bits, significantly saving drilling costs.

[0003] Publication No. CN206200196U discloses a diamond drill, characterized in that it includes a diamond drill body (1) arranged vertically downward, the lower section of the diamond drill body (1) is a grinding area, the middle section of the diamond drill body (1) is a chip removal area, and the upper section of the diamond drill body (1) is a mounting area. The outer wall of the diamond drill body (1) in the grinding area is provided with a thread (2), and a semicircular water outlet (3) is provided on the front, back, left, and right sides of the bottom of the diamond drill body (1). A "<"-shaped discharge hole (4) is provided on the front wall and the rear wall of the diamond drill body (1) in the chip removal area. Diamonds are provided on the inner wall, outer wall and bottom of the grinding area, and the diamonds include crushed PCD polycrystalline diamonds or gem-grade single crystal diamonds. The utility model diamond drill has the advantages of strong cutting capacity, long service life, low production cost and high production efficiency.

[0004] The above technical solution has some problems in practical application. Since the diamond drill has a high working intensity, its drill bit is prone to wear. When the drill bit of the diamond drill is damaged, it can only be replaced as a whole, which is costly.
