Q:What is a square hole drill and can be machined square hole?: You can drill through the square hole, but not once.

Q:How big expansion screw does the 6mm bit have?: Expansion screw generally refers to the metal expansion screws, expansion screws fixed, but the use of wedge slope to promote expansion, friction, grip force, to achieve fixed effect. One end of the screw is threaded, and the other has taper. Outside the bread (some tin pipe), iron cylinder (steel tube) has several half incision, put them together into the wall lay the hole, then the lock nut, the nut screw pull, pull cylinder taper iron, iron cylinder is open up, so tightly fixed on the wall, generally used for protection bar, awning, air conditioning and other fastening in the cement, bricks and other materials. But its fixed is not very reliable, if the load has a larger vibration, may be loose, so it is not recommended for the installation of ceiling fans.

Q:How do the new pros and cons drill the drill bit without the key?: This is the hand chuck chuck, is divided into two parts, the front end is used for elastic, rear end is fixed, you want to unload the drill, left to right back to the front to turn in the opposite direction can be loose, Anhui, Bozhou, great electrical firm opened, welcome patronage. Address is: Wanfu market, B building, No. 76-77, which is the general agent of broad brand. Cost-effective

Q:What's the angle of a standard twist drill?: The front angle is 2, and the front angle is the projection angle of the two main cutting edges on the plane parallel to them. The small front angle is easy to cut into the workpiece, the axial resistance is smaller, and the working length of the cutting edge is increased, and the nominal thickness of the cutting layer is reduced, which is beneficial to heat dissipation and to improve the durability of the cutting tool;

Q:Why not hammer drill iron: Electric hammer drill (electric hammer drill), is the "two function drill" and "hammer" handheld electric tool, "rotary cutting drill", with the impact of the impact mechanism of driving impact drill bit, drill driven in rotation at the same time, there is a direction perpendicular to the rotation of the rotary drill the reciprocating motion of the hammer. For concrete, brick, tile, marble and other materials drilling. "Hammer" to drive the impact force of drill rod, used for concrete, bricks and other materials on the slotting, holes or broken concrete etc..

Q:Is it OK to drill holes on tiles with an ordinary bit? Will the tiles crack?: Not a bit of the problem, mainly tile problems, good quality tiles are not easy to crack.

Q:M6 screws should drill big holes: 1.M6 need to drill 4.8mm hole thread. Calculation method:2. generally speaking, the diameter of the Gong bolt multiplied by 0.86 is the diameter of the hole to be drilled.3.M6 thread refers to the nominal diameter of 6mm coarse tooth common thread.

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:What causes the drill bit to break at the end of the hole?: When the speed is low, the feed is too large.If the cutting resistance is greater than the twist strength of the drill, the bit can be broken when the speed is low.

Q:What measures can be taken to prevent the bit from breaking?: In drilling, the pressure must not be too great for the drilling hole to avoid breaking the bit. Especially in the hole is drilled, the drill tip has been exposed to the bottom surface, the feed speed must be slowed down, feed pressure must be reduced. In addition, if the drill is not fast, do not force to continue to use, so that the most likely to break the drill bit.
