Q: Which is better, a white drill or a black drill?: Black for rolling, worst. White for the edge and grinding, grinding than the edge of the better, grinding polished better, the price is higher

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: 1 inches of steel plate, what drill can drill through?: 1 cm thick steel plates can be drilled through plain twist drills. Twist drill is the most widely used tool in hole cutting tools. Its material is usually high speed tool steel or carbide.

Q: How to install expansion screw? How big is the screw? What size is it? Or what? How do you see the size?: M6, for example, uses a drill with a diameter of 8, so that the expansion part of the expansion screw is able to penetrate the wall.

Q: Do you have any special drill for aluminum alloy?: Aluminum alloy, copper, stainless steel, the hardness of these materials are not high, aluminum alloy, copper soft, frequent drilling process, easy to cut, and there will be a lot of burr. The best choice for some Aluminum Alloy drill bits for different materials when drilling drill main cutting edge angle will be different, the best selection of aluminum cutting angle of 120-135 degrees, the feed is not too high, due to the low, if the best friend can understand the material selection of M42, M35 or 6542, not bad bit a few drill does not move. The bit is divided into a rolling bit and a full grinding drill, and the whole grinding drill is 30% more expensive than the rolling mill, but the effect is much better than that of the rolling mill.

The purpose is to drill holes and feed quickly. That is to say, drilling speed is very fast

Q: How to use glass drills?: With the drill bit in the hole on the glass, water glass drill bit 80 degree angle at the hole grooves and then gradually transferred to a glass surface 90 degrees vertical to continue drilling, and continue to add water cooling the drill bit when drilling, 5mm stopped the machine out the bit within the glass pieces and then drilling. Clean up until the desired depth is reached.
