Q:What drill is drilled after quenching?
Quenching: a heat treatment process for quenching of metals and glass. Steel the steel quenching is heated to the critical temperature Ac3 (hyposteel) or Ac1 (hypereutectoid steel) above the temperature, holding time, so that all or part of 1 Austenitic, then the cooling rate is greater than the critical cooling rate of fast cooling to below Ms (or near Ms ISOTHERMAL MARTENSITE () or bainite) heat treatment process transformation. Aluminum alloys, copper alloys, titanium alloys, tempered glass and other materials are usually treated by solid solution or heat treatment with rapid cooling process.
Q:Want to buy a hammer, with the decoration of the house, how much more appropriate aperture?
Hammer is a kind of electric drill, mainly used in the concrete slab. Brick and stone on the hole. Hammer is the use of compressed gas piston, impact drill bit, need not make much effort, it can open 6--100mm in concrete, brick, stone and other hard materials on the hole hammer in the above-mentioned materials on the opening of high efficiency, but it is not suitable for open hole in the metal. But some multifunctional electric hammer, adjusted to the appropriate position with appropriate drill can replace the ordinary electric drill, electric use.
Q:What are the differences between a twist drill and a construction drill? Where are they used?

Q:How big bits are used for expansion bolts?
Know the expansion bolt diameter, can find out the tube diameter; the borehole diameter is slightly greater than the diameter of expansion pipe can be used, and expansion pipe of the same diameter aperture is slightly larger than the drill out tube diameter.
