Q:How to recognize the quality of twist drills?
In addition, there are also listening to the sound, knocking glass, using a grinding machine to play sparks, see color, etc.. These need experience, like picking watermelon, each has its own coup, different varieties, methods are also quite different. Usually, the more crisp we are, the more glass we have, the slightest spark, and the more red the spark, the better the bit material.

Drilling, drilling, heating, if the temperature is too high, will lead to accelerated drilling wear, and even annealing.The cutting heat in the cutting process due to friction deformation and cutting material separation and rub the cut material between, so drilling after jobs have hot feeling, but not as long as the cutting drill out of the blue or purple, generally does not cause a bit of annealing.
Q:What drill is used in stainless iron drilling?. What color?
The best is to make the stainless steel material of cobalt containing material with high speed steel drill, high-speed steel drill is cobalt containing silver, do not know the landlord of the silver white bit is not high speed steel containing cobalt, if not, you can buy only high speed steel cobaltiferous material drill (also called stainless steel special under the best bit), buy imported, not much of your money, the quality difference is too large domestic drill.

Casting angle of general 140-145, such as feed reasons for the high hardness of cutting force is slow, mainly concentrated in the front edge, if the bit is too sharp will wear out quickly, and the blade angle blade angle relative small blade due to natural force will be small and short.
