Q: M3 threaded hole. The bottom should choose large diameter drill bit: What do you not know about screw diameter reduction? M3 the pitch is 0.5, that is, 3-0.5=2.5.. If it is a piece, it can be larger. Choose 2.55 to 2.6 of the drill bit. All other materials are 2.5.

Q: Relationship between bit diameter and rotation speed: There are many factors affecting the size of the drill bit and the speed of the drill. Theoretically, the speed of the bit is mainly the linear velocity of the bit, because the diameter of the bit is small and the speed of the bit is low. The diameter of the big drill is big and the line speed is high.

Q: What are the weight specifications of the drill pile when the bridge pile foundation is constructed?: Impact drilling in two main forms, one for earth or soft rock using tubular hammer, one for hard rock is solid hammer, the general hammer is about 4-5t, if you want to increase, you can hammer on the steel bar plus counterweight.

Q: M6 threads need to drill much bottom?: M6 is generally 4.8 of the bottom, but I do find it hard to die when the attack!! So basically use 5 or 5.2!

Q: By drilling with a bit, why is the hole drilled straight 2 larger than the diameter of the drill?: Hardness of the machined material --- determine the size of the drill point: cast iron is used at 135 degrees - 140 degrees; aluminum alloy is about 120 degrees;

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: What drill is used in stainless iron drilling?. What color?: Drill. Ordinary sealed steel drill and outside. But when the water in the drilling bit to cool down. Because of the two bit edge part protruding is sealed steel. If a steel meet. What a high temperature. The carbon element will be between their chemical together. You can drill the drill is not moving. We often say a bit burnt. Hole is alloy. In theory it is. But not jitter. A jitter. Alloy was dropped. The bit was scrapped. In the course of the stainless steel punch. It is better to play in Taiwan. Taiwan controlled rotary speed can be adjusted.. it can reduce the friction and temperature. But to drill for long. Or water. Methods. A mineral water bottle. The bottle turned a little empty hand squeeze on it

Q: What is the difference between cobalt titanium alloy drill: Is coated on the surface of the object by an electroplating method on the outside with a titanium protective layer,An element of the periodic table of cobalt chemical elements, having an atomic number of 27 and an atomic weight of 58.9332

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

Q: What do you use for drilling walls?: The hammer can drill the wall. An electric drill is out of the question. Electric drill, electric hammer, impact drill is used to punch the hammer, generally used to drill holes in the concrete and other hard objects, the drill bit is alloy steel, in drilling at the same time, the function of a hammer.
