1.Drill is a rotary drill head, and the cutting ability of the tool end, generally steel SK, or high speed steel SKH2, SKH3 materials prepared by milling or rolling and then by quenching and tempering heat treatment after the grinding is made by drilling in metal or other material, its use very wide range, can be applied using a drill press, lathe, milling machine, hand drills and other machine tools.
2 types of drill
A. By the classification structure
(1) Integral Drill: Drill top, drill body, the drill shank made of the same material as a whole.
(2) An end welded drill, drill bit welded carbide from the top.
B. Classification according to drill tenon
(1) straight shank drills: Drill diameter in ψ13.0mm the following, all using straight shank.
(2) taper shank drill bit: drill shank is tapered shape, which generally are used taper Morse taper.
C. Categories by Purpose
(A) of the center drill: drilling ships for the front center with play, with tapered distal end 60 °, 75 °, 90 °, etc., for use when the lathe tailstock support operations, should be held with the lathe center drill 60 ° tailstock Quill 60 ° mating.
(2) twist drill: Use a drill bit is the most widely used industrial manufacturing, we generally use is the twist drill.
(3) cemented carbide drill: front drill body or all in cemented carbide cutting tool materials, processing materials used in drilling (4) drill hole: the drill hole itself prescribe, cutting agents Compiling through this hole to edge part, to take away the heat and chips generally use this drill rotating work piece, while still drill
(5) deep drill: the first stone for the barrel and the guarantee of drilling, also known as the barrel drill. Deep drill a straight groove, cut a quarter of a tube in the middle part of the chip to produce a cutting edge
(6) Drill Reamer: the need for mass production, its front end of the drill, the back end of reamers, reamer margin drill diameter and the diameter of a thin reaming allowance, there are also tapping screw drill in mixed use, it also known as mixed drill.
(7) taper drill: When processing die inlet, the taper drill may be used.
(8) cylindrical hole drill: We call countersunk head cutter, this drill has a smaller portion of the front end of a road called the rod diameter.
(9) cone drill hole: the use of tapered hole drilling, which has a front angle 90 °, 60 °, and other, chamfering tool we use is a conical hole drill.
(10) Triangle drill: drill used in a drill, drill shank made its surface triangles that can be securely attached drill chuck
nonstandard oildrill fitting
Drill solid material is used in the drilling of through holes or blind holes, and is able to have a hole reaming tool. Commonly used mainly twist drill, flat drill, center drill, deep hole drilling and core drill. Drill and countersink reamer, although not on the physical material drilling, but the habit will also drill them into a class.
High-speed steel hollow drill, also known as coring drill or hole saw,
Drill Category: HSS drill bits, carbide drill bits, carbide drill bits; cutting of depth: 35MM, 50MM, 100M; suitable rig: Magnetic imported drill, magnetic drill, magnetic drill domestically, magnets drill, drill iron absorption, steel drill, magnetic drill machine, bench drill, drill and so on.
Diameter specifications: 12MM to 100MM; drill main materials are high-speed steel; powder metallurgy; Carbide category. Drill axis inclined to the plane of the wheel angle of 60 °. This angle is the angle of the drill bit front, right angle at this time, will directly affect the size of the drill angle of the main cutting edge and chisel edge angle and shape.
Here is the relationship between the position of the drill axis and the wheel surface, taken on the line 60 °, this angle can be generally more thorough understanding. Here we should note before sharpening drill horizontal position and the relative angular position, both to be balanced, not in order to settle the edge while ignoring gracefully degree angle, or the angle of the neglect to gracefully settle edge.
The length of the drill diameter and larger, which tends to increase bending. Reducing the aspect ratio can be reduced deflection force, thus avoiding errors drill breakage and increase the aperture. Deep hole drill specifications required a larger aspect ratio. Usually more than three times the diameter of the hole is deep, "deep", while the micro-drill hole depth generally have exceeded this limit

Drilling function:
① obtain first-hand information on the subsurface geology in kind, namely removal from the core drilling, mine heart, debris or liquid, gaseous
Samples, sidewall core samples up ore samples taken from the hole wall when necessary;
② as geophysical logging channels, access to a variety of rock layers geophysical information;
③ as an artificial channel aquifer hydrogeological observation dynamic;
④ some drilling may be combined exploration and mining, underground mining, geothermal, oil and gas.
Drilling has been widely used in many sectors of the national economy, according to use, drilling can be divided into the following categories:
① geological survey or exploration drilling for understanding the geological structure, prospecting or proven mineral reserves;
② hydrogeological drilling, survey and groundwater hydrology geology;
③ wells, as industry, agriculture, national defense and living resource exploitation or recharge groundwater and hydrogeological data have substantial effects;
④ engineering geological drilling, survey or construction plant-based, dam, reservoir, bridges and roads and other proven engineering
Foundation status;
⑤ oil drilling, exploration and development of oil and natural gas;
⑥ geothermal drilling, exploration and development of underground hot water and steam resources;
⑦ engineering foundation construction drilling, borehole construction of the foundation for the reinforcement and application on the basis of the pile or piles of construction;
⑧ development drilling, mining underground brine, dissolve the rock salt, sulfur, combustion of underground coal gasification, etc.;
Auxiliary ⑨ mining or drilling tunnels and other projects, when mining or tunneling ventilation, drainage, water exploration, gas exploration, freezing, transportation and installation of pipeline construction and communications, blasting, sampling, grouting borehole construction.
