Q:Bit grinding, hair and technical requirements: There is now a knife grinding machine YN-01A+ drill grinding machine grinding twist drill on the market, SG fast drilling, DG long short blade edge deep hole drilling, in the processing of 3D within the hole, the ordinary twist drill into fast drilling, without positioning, direct drilling, hole position accuracy and the efficiency on the use of ultra fast; DG to the mill, if it is less than 10D or above according to the processing of materials and machine tools and other site by cutting and grinding method when less than 3D above 5D; worn by YN-01A+ zzm-a drill bit to meet the basic situation the essence of drill bit efficiency 2-3 times, the service life of the drill bit can provide 3-5 times; this machine operation is simple and fast, without experience in technology, one minute can grind a bit.

Q:What is the standard angle of the drill bit?: The standard angle of the drill depends on the material of the drill and the material of the material to be machined. But the most common angle is 118 degrees.

Q:I want to be in the stainless steel frame and fixed drill a few screws, with what bit and screw: It is the best to drill stainless steel with carbide drills, and if you do not have a carbide drill, you can drill with an ordinary bit;

Q:What is the geometric angle of the drill bit?: A TRUSCO bit is a tool used to drill through holes or blind holes in solid material and to expand existing holes. The TRUSCO bit acts on its head, and its cutting edge and the cross edge act as a tool. In order to make the taper surface of the cutting part not touching the workpiece, the value of the rear angle and back angle should be selected according to the material of the workpiece.

Q:Electric hammer drill killed what should take down: 1, backward extrusion head, drill can be pulled out.2, black down, iron also press down, it came out.3, there may be a problem that the pearl inside the chuck. The drill down, pressure head black chuck, a few more to return a bit range.

Q:What causes the drill bit to break at the end of the hole?: Small bit not used high speed, with small feed amount.A small drill can withstand torque is small, the use of high speed with a small amount of feed, can reduce the small rotating cutting output, so as not to drill to bear large torque.

Q:The maximum diameter of the hammer is fixed up? Can I open the hole? How does an electric drill screw in? How big is the drill bit?: Hammer of different sizes have different maximum diameter of the drill bit.

Q:How big is the 6 bit that the worker says?: The default length units for machining and mechanical drawing are millimeters,
