Diamond drill bit detailed classification introduction

Diamond PDC anchor bit

Also known as rock drills, anchor drills, two wings diamond compact bit, drilling in coal mine area is mainly used for roof support, anchor rod and anchor rope support before drilling, in the field of geological exploration, can be used in hard formation and hard rock drilling construction, slope support engineering, such as its main models are 28 of 30 32 blade form generally for the two wings, The form of composite piece is the combination of one or half pieces of each blade on one side. The specification of composite piece is 1304 flat 1304 ball 1305 flat 1305 ball 1304 cone tooth.

Diamond PDC coreless drill bit

Also known as core bit, water drilling head, steel body bit, steel body PDC bit, is made of nickel, chromium, molybdenum alloy machining molding. After heat treatment, the drill bit body is drilled, and the artificial polycrystalline diamond (PDC) composite sheet is pressed into the (tightly fit) bit body, with cylindrical tungsten carbide diameter protection. It is mainly used for water exploration and gas exploration in coal mines. Common blade forms are three wings, four wings. The form of composite piece is one-side blade welding 1304 1305 1308 half piece, half piece, full piece composite piece, middle column welding 1304 1305 composite piece, one-side blade welding alloy diameter guard bar.

Diamond PDC sintered body bit

Also known as hard rock bit, water drilling head, tire bit, sintered body bit, tire type diamond composite piece (PDC) bit is a kind of cutting bit that welding diamond composite piece on drill head tire by brazing. The tire bit is sintered with tungsten carbide powder and brazed on the tungsten carbide by artificial polycrystalline diamond composite sheet. The diameter is kept by natural diamond. The common blade form is three wings, and the composite piece form is 1304 1305 1308 half piece, half piece, and the whole composite piece can be divided into flat-top sintered body and concave sintered body bit. It is mainly applied to hard rock drilling in deep hole drilling of coal mine. Grinding hard rock and rock gap can be achieved by cutting the hardness of its body with PDC composite sheet.

Diamond PDC scraper bit

Also known as rock drill, water drill head, tower drill. Drag bit as steel body form, discharge above the cutting blade for iron plate after welding is in the shape of tower its use and the concave bit use almost the same PDC bit in soft coal seam has better drilling and discharge effect of blade forms are three wings, carried out in accordance with the diameter size of teeth, more compact form for 1304, 1305 and a half piece of film.

Diamond PDC reaming bit

Also called guide bit, holing bit, cutting bit. The main type is a combination of multiple concave bit welding for large hole follow-up after the hole has been formed. Diamond guided drill is also a kind of reaming drill, which uses a round steel machining guide head, with a diameter guard bar for diameter protection, and a blade for cutting and reaming below. Commonly used specifications are: φ75-φ113φ94-φ113φ94-φ153φ94-φ260.
