Diamond Bit Specifications And Models

Drill bits are used for drilling. Generally speaking, it is OK for drilling bits to be used in household decoration, but they can not be used for long time on hard materials such as rocks. Diamond bits can be used in this environment. Diamond bits can not only be used for a long time, but also be reused. The repaired diamond bits can be used with the same effect as the diamond bits from the factory, which can save drilling costs a lot.

Diamond Bit Specifications and Models
Diamond PDC anchor bit
It is also called rock drill bit, anchor cable drill bit, two-wing diamond composite chip drill bit. It is mainly used for roof support, anchor rod and drilling before anchor cable support in the field of coal mine drilling. In the field of geological exploration, it can be used for drilling construction in hard strata and medium-hard rock strata, slope support and other projects. Its main type is 2830 32 blade wing, which is usually two-wing, and the composite blade is a combination of one or half blade on one side. The size of the composite sheet is 1304 flat 1304 balls 1305 flat 1305 balls 1304 conical teeth.

Diamond PDC Centerless Bit
Also known as core drill bit, water drill bit, steel drill bit, steel PDC bit, is machined and formed with nickel, chromium and molybdenum alloys. After heat treatment, drill holes on the body of the drill, press the PDC of synthetic polycrystalline diamond composite sheet into the body of the drill (tight fit), and maintain the diameter with cylindrical tungsten carbide. It is mainly used for water exploration and gas detection in coal mine. The common form of blade wing is three-wing and four-wing. Composite sheet is one-sided blade-wing welding 1304 1305 1308 half, most half, full sheet, intermediate pillar welding 1304 1305 composite sheet, and one-sided blade-wing welding alloy diaphragm strip.

Diamond PDC sintered bit
Also known as hard rock drill bit, water drill bit, matrix drill bit, sintered body drill bit, matrix diamond compound (PDC) drill bit is a cutting drill bit, in which the diamond compound sheet is brazed on the body of the drill bit. Cartridge drill bit is sintered with tungsten carbide powder and brazed on tungsten carbide body with synthetic polycrystalline diamond composite sheet. The common form of blade is three-wing, and the composite sheet is 1304 1305 1308 half. Most of the composite sheet can be divided into flat-top sintered body and concave sintered body drill bit. It is mainly used in hard rock drilling in deep hole drilling in coal mine. It relies on the rigidity of the matrix and cutting of PDC composite sheet. To achieve grinding of hard rock and fracture gaps.

Diamond PDC Scraper Bit
Also known as rock drill bit, water drill bit, tower drill bit. The scraper bit is steel body, and the upper slag discharge cutting blade wing is pylon shaped after welding. Its use and concave bit use are basically the same. PDC bits are mainly three-wing blades with better drilling and slag removal effect in medium-soft coal seams. The blades are arranged according to diameter and size, and most of the composite blades are 130 1305 half full sheets.

Diamond PDC reaming bit
Also known as pilot drill, hole drill, pin drill. The main type is the combination welding of multiple concave drills for follow-up of large holes after they have been drilled. Diamond guide bits are also one kind of reaming bits. They are machined with round steel guide bits with diamond guard strips attached to them for diameter preservation and blades left underneath for reaming. Common specifications include: φ 75- φ 113 φ 94- φ 113 φ 94- φ 153 φ 94- φ 260.
