Q:What drill is best?: Material is 6542, even better, it contains cobalt... Then coated TiAIN pure blackThe effect is better than your black brownI have a punch hereOrdinary processing around 3WAfter coating processing can do 25-30W or soThe effect is very strongThe drill you want, I can do for you. I'm from the tool factory

Q:What bits of percussion drills are made of?: Purpose: hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.

Q:What's the difference between an impact drill and an ordinary electric drill?: The percussive drill works by rotating and impacting and can be used for natural stones or concrete. Impact drill work in a drill chuck adjustment knob, adjustable normal electric drills and impact drills in two ways. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, the impact force is far less than the hammer. It can also drill reinforced concrete, but it doesn't work. Hammer is a kind of electric drill, mainly used in the concrete slab. Brick and stone on the hole.

Q:I'm going to drill 10.5 of the thread. How many holes do I have to drill before tapping? How big is the tap?: As a tool for machining internal thread taps, according to the shape can be divided into straight edge and screw tap tap, in accordance with the use of the environment can be divided into hand taps and machine taps, made in accordance with the specifications, and can be divided into metric, British tap, according to the origin can be divided into domestic and imported tap tap. Tap is the most important tool for operators to process thread.

Q:What's the angle of a standard twist drill?: It is divided into 135 degrees and 118 degrees135 degrees vertex angle is mainly used for more hard workpiece, this design is to improve the positioning of the drill bit accurate (because 135 degrees need to open the back angle), broken cutting fastThe drill with a top angle of 118 degrees is mainly used for soft materials. The purpose is to drill holes and feed quickly. That is to say, drilling speed is very fast

Q:Which material, gb1436 and 6542, has a good drill?: 6542 refers to the content of various elements in this material. For example, 6542 is W (tungsten) content of about 6%, Mo content of 5%, Cr content of about 4%, V content of about 2%.

Q:Relationship between bit diameter and rotation speed: There are many factors affecting the size of the drill bit and the speed of the drill. Theoretically, the speed of the bit is mainly the linear velocity of the bit, because the diameter of the bit is small and the speed of the bit is low. The diameter of the big drill is big and the line speed is high.

Q:What does M3x0.5 mean by tapping a drill bit?: M3 * 0.5 represents a 3 mm screw with a pitch of 0.5 mm. With a diameter of 3 minus 0.5 equals 2.5 pitch dia. It is to drill 2.5 holes with a drill, and then tap with a M3 tap.

Q:What kind of steel do you need to drill?!: A cemented carbide drill bit with an average size of 1 microns. This kind of drill not only has high hardness, but also improves the compressive and bending strength. In order to save the cost of many bits by welding handle structure, the original bit for the whole hard alloy drill, the back part of the handle adopts stainless steel, but the cost is greatly reduced due to the use of different materials and its dynamic concentricity is inferior to the whole hard alloy bit, especially in the aspect of small diameter.

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.
