Q:How do the front and back angles of the drill change? How does it affect drilling?
The front angle of the drill is the angle of the spiral groove of the drill. It is generally unchanged. After the drill angle should change according to the situation of the processing hole; for example, when drilling, the drill bit at the outer edge of the general angle generally between 8~14 degrees, if you want to draw it by fossa, orifice chamfering drill, drill angle will be smaller, the cutting edge of the drill will be down, like this helps maintain a steady state of the drill bit, rowed out nest and chamfer to smooth, does not produce the phenomenon of polygon.
Q:CNC machine tools I use 6.5 bit drilling out is 6.7, what method can be solved?
Also, bit clamping and grinding will also affect the drilling size to varying degrees.Remedy is:1, the size of the hole strict requirements of the workpiece, you can drill after the hinge.2, the hole size requirements are not too strict, with 6.5 or 6.6 drill directly drilling. In mass production, the first workpiece must be measured and checked.
Q:The basic angle of twist drill
Front angle gamma Om (since the front surface of the twist drill is a spiral surface, the front angles of the points on the main cutting edge are different. From the outside, the center angle decreases gradually. The rake angle at the nose point is about 30 degrees, and about -30 degrees near the cross edge. The front angle on the cross edge is -50 degrees to -60 degrees.

General twist drill rolling and grinding, high quality grinding, I used, there are good brands in the processing of steel parts on the whole: drill, drill Gongquan full amount, mine drill, drill the Far East

Q:What drill holes are used in stainless steel basins?
Crazy, what do you want to do?. If the drill or two eyes, ordinary bits, slow speed can. If you drill it into a sieve, choose a high temperature resistant steel bit. To the hardware store to ask, buy a professional drill stainless steel twist drill, it can save effort point.

Do not add cutting fluid is difficult to control, do not burn, there is no way to use compressed air blowing it will be better, and drill down when the knife properly, will be better.
Q:Cobalt containing special stainless steel drill bit, 4mm angle, do not move?
What drill, what power, what speed?.Iron and steel complex, hard harder than stainless steel.The drill is to be sharpened.
