- Q:Do you have any special drill for aluminum alloy?
- Aluminum alloy, copper, stainless steel, these materials are not high hardness, aluminum alloy, copper soft, frequent drilling process, it is easy to have cutting, there will be a lot of burrs, aluminum alloy special drill.
- Q:New drills usually need sharpening before they can be used. Why?
- The back angle of the new drill is grinded by the drill mill, which is made of special grinding bit equipment, and the angle is very straight. There is no circular arc R transition. If directly used to drill, drill will produce vibration and beating, the hole will be multi prismatic. Therefore, the new drill is usually used to drill the drill bit again according to the drilling condition, to grind out the back angle of the arc transition and the proper vertex angle, so that the drill bit can be drilled steadily.
- Q:Can twist drills drill through wall tiles?
- A drill bit (Drills) is a tool used to drill through holes or blind holes in solid material and to expand existing holes. The commonly used drills are mainly twist drills, flat drills, center drills, deep hole drills and casing drills. Reaming drill and countersink drill is not in solid material drilling, but it is also customary to put them in a bit.
- Q:The basic angle of twist drill
- The front angle is 2, and the front angle is the projection angle of the two main cutting edges on the plane parallel to them. A small sharp angle easily cut workpiece, axial force is small, and the cutting edge length increases, cutting nominal thickness decreases, conducive to heat dissipation and improve tool life; if the front angle is too small, then the bit intensity of deformation increases, the torque is increased, the breakage of the drill bit. Therefore, a reasonable front angle should be sharpened according to the strength and hardness of the workpiece material. The front angle of the standard twist drill is 2 and phi is 118 degrees
- Q:Deep hole refers to the diameter of drill bits more than times, called deep hole
- Gun drill: only one cutting part, which was first used to process barrels. During drilling, the cutting fluid enters from the middle of the drill pipe and is injected into the cutting area through a small hole in the head of the drill bit and then removed from the V groove of the drill bit with the chip. The gun drill is suitable for deep holes with a bore diameter of 2~20 mm and a ratio of Kong Shen to aperture greater than 100. BTA deep hole drilling: the cutting fluid is fed from the gap between the drill pipe and the hole wall, and the cuttings are expelled from the inner hole of the drill pipe by the pressure of the cutting fluid. BTA deep hole drilling is suitable for drilling more than 6 mm hole diameter, hole depth and aperture ratio of less than 100 of the deep hole, and its production efficiency is more than 3 times higher than the gun drilling. The jet drilling: a multi edge deep hole drilling, inside and outside two layer drill pipe, most cutting fluid from inside and outside the drill pipe into the cutting area gap, and then together with the inner tube into the chip; the crescent hole and a small portion of the cutting fluid through the inner tube into the tail end of the inner tube jet formation, effect, low pressure area, help suction chip. The jet drilling does not require a strict cutting fluid seal. It is suitable for drilling deep holes with a diameter of more than 18 mm, Kong Shen and a bore ratio of less than 100.
- Q:What bit is hard, not easy to wear and punch?
- Stainless steel drilling bit, not the problem, of course, is not Never mind, is to buy a bottle of vinegar, vinegar, vinegar is vinegar can be, not tried.
- Q:Who can do this? Put the drill into it
- The method of assembling drill bits is incorrect. The easiest way is to clamp the hammer hammer down the legs, with the left index finger on four set head forward, pointing to the direction of the motor to pull the thumb and ring sleeve. Take the drill with your right hand
- Q:How long the hand-held electric hammer drill
- Matched with various electric machine, concrete, brick and other building materials for hard drilling. The utility model is a drilling tool with wide use and high efficiency in the construction and installation industry.
- Q:14 what big expansion wire does the drill use?
- The size of the bit corresponding to the expansion bolt:Bolt, =M16, drill bit, bolt diameter directlyBolt =M20, in addition to the buried depth of =170mm, take the diameter of 24mm, the diameter of the drill bolt
- Q:M2.5 hit the bottom teeth with much bit
- M2.5 is the diameter, you want to use this diameter to subtract the distance of the tooth, that is, the diameter of the drill. In the metric system, the distance of M2.5 is 0.45.
