- Q:What is the maximum available drill bit for an electric drill with a maximum diameter of 10mm?
- Of course, if it is not a cylindrical drill, but a hole opener, it can be as large as 100mm and open a round hole on a low density material such as a large board.
- Q:Drills, drills, heating drills, will they be annealed?
- So in need of cutting fluid filling drilling, cutting fluid can take away a lot of heat cutting when cutting, cutting temperature, and the cutting fluid can penetrate into the workpiece, cutting tool, the lubricating film formed between the chip and the tool and the workpiece, can reduce the friction between the chip, thereby reducing the cutting deformation of bue growth inhibition. And the cutting fluid can be a small chip away to avoid clogging timely or scratch the workpiece machined surface, reduce the surface roughness value, reduce the thermal deformation of workpiece and ensure the machining accuracy and improve production efficiency.
- Q:What is a square hole drill and can be machined square hole?
- The three vertices of an equilateral triangle as the center, edge radius at the apex on the side arc, get leelo triangle. As it is easy to prove that the triangle leelo properties, its width is equal to the structural length of the equilateral triangle. The length of the triangle leelo width within the square rotates, each corner of the path traversed basically is a square.
- Q:Angle action and characteristics of standard 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.
- Q:Why not hammer drill iron
- Motor protection device: comprehensive in use will inevitably have hard granular access to a machine (especially on the machine to work on drilling, such as drilling on the top wall), if there is no certain motor protection, rotating at high speed can easily be hard break or scratch enameled wire, eventually lead to the motor failure.5, positive function: can make use of a wider range of electric hammer drill, the form is mainly realized through switch or adjust the brush position, usually big tools will be used to adjust the brush position (rotating brush) to achieve the benefits of doing so is easy to operate, effectively inhibit the spark to protect motor commutator, prolong the use life6, hammer drill double function: both the impact hammer, electric drill and penetration.

- Q:What drill is used in stainless iron drilling?. What color?

Or if not, can change the drill bit Ti, Ti is abrasion resistant, ordinary life is 3 times more than the standard twist drill]
- Q:How do the drills grind?
- A formula: "edge on 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
