Q:How much bit should we use to punch the M5 hole? Tapping with Duodasi attack? Why use 8.3 drill bit in the hole of M10? How do you know how big it is to punch and tap?
The diameter of the drill is usually marked at the drill handle. If it is not marked, it should be measured with a measuring device. M5*20 5.5 screw drilling hole is played, not the threaded hole.
Q:How many diamond grinding wheels should be used for an alloy bit?
If the hard alloy is generally 100 mesh coarse grinding, and then finishing 180, we have foreign customers dedicated to the electroplating grinding wheel are generally parallel to that, the two particle size. Plain drills and cutters use CBN wheels.
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:What drill holes are used to break the screw?
If the screw is broken and the drilling is not good, it is recommended to solve the problem with edm. A six or a slot is machined at the broken screw and then the screw is broken inside with a six square wrench or screwdriver. The electrode size is different, can process different sizes of broken screws, M3-M50 can.
Q:Drill hammer type matching specifications
The four can only handle four round hole hammer drill hole, the domestic side Bingsi pit with general electric hammer Bingsi pit bit, round handle can be fitted with but only occasionally use.

Q:How do you drill a sharpening bit?
The blade is fixed against the wheel surface." This is the first step between the bit and the grinding wheel, and it is often the students who have not cut the edges of the blade, so they start sharpening on the grinding wheel. It must be hard to wear. The blade here"The mouth" is the main cutting edge, and the "cut out" means the main cutting edge of the grinding part is in the horizontal position. "Wheel surface" refers to the surface of the grinding wheel. "By" means slowly moving closer. The drill cannot contact the grinding wheel at this time.
Q:What is the standard angle of the drill bit?
For example, HSS high-speed steel drill bit: vertex angle is generally 118 degrees, sometimes greater than 130 degrees; sharp blade; accuracy (blade height difference, symmetry, jitter) requirements are relatively low. There are many ways to correct the transverse blade. Hole roughing and less demanding, we generally use more. HM carbide drills: the top angle is generally 140 degrees; straight fluted drills are usually 130 degrees; and three edge drills are usually 150 degrees. The blade and nose (edge) are not sharp, often passivated, or inverted blade and chamfering, and require high accuracy. The horizontal edge is often into a S- shape, in favor of chip breaking
