Q:Woodworking drills, classification, woodworking drills are those categories, the more specific the better
At present, the international woodworking drill popular three awl auger drill bit, drilling ladder.Three sharp woodworking drill easy to locate, high-speed cutting, the wood powder, usually used to process small holes.
Q:What is the minimum specification for hollow drill bits?
Hollow drill bits are available:1. diameter minimum 12mm, maximum can do 160mm;2. drilling depth are 25mm, 35mm, 50mm, 75mm, 100mm and so on;3. cut to 35mm: in diameter, 12mm to 50mm in diameter. Cut depth is 50mm: diameter from 12mm to 100mm. Cut depth is 75mm: diameter from 16mm to 100mm. Cut depth is 100mm: diameter from 18mm to 100mm.
Q:How do we calculate the length of a drill for a bored pile drill?
The length of the drill bit is reduced by 2/3, or 1/3 of the drill bit.
Q:How to recognize the quality of twist drills?
The first is the material: the market has 424160843416342934, 6542, M35, M42 in turn.The second is the process: straight drill are rolling, milling, grinding, milling and drilling are rolling. Ground is the best. The rolling efficiency is much higher than that of milling, so most of the bit is rolled. High quality high speed steel is generally used in grinding.
Q:What are the brands of homemade twist drills?
. After roasting yellow, the drill looks yellow, not white or gold. In addition, what foreign doctors are actually made in China, because foreign countries have been eliminated, the total production of this product. The added value is too low. New twist cards and old brands in china. Veteran of the most stable should be Kazakhstan workers, workers. But to tell the truth, in fact, as long as the material is not deceptive, the accuracy of the geometric angle, many companies can do such a degree.
Q:By drilling with a bit, why is the hole drilled straight 2 larger than the diameter of the drill?
Drill bit, drill out of the hole than the drill diameter, because drilling cuttings will increase the extrusion aperture; at the same time, for the convenience of a chip it is necessary to improve bit will increase; if the concentricity is not good, it will increase more.
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:The basic angle of twist drill
The back angle of the selected point on the main cutting edge of the twist angle alpha Om is expressed by the feed back angle alpha Om in the point column section. The column section is the point m of the main cutting edge, a line parallel to the axis of the drill, and the cylindrical surface formed by the rotation of the line around the center of the bit. The alpha Om changes along the main cutting edge, and the closer to the center, the greater the alpha Om. The back angle of the outer edge of the twist drill is usually 8 to 10 degrees, and the back angle of the transverse blade is 20 to 25 degrees. This can compensate for the influence of the angle of the main cutting edge on the actual working angle of the main cutting edge due to the axial feed motion of the bit, and can adapt to the change of the front angle.
Q:Cobalt containing special stainless steel drill bit, 4mm angle, do not move?
No matter what drill, the head must be sharpened! The small drill can be struck because the front edge is well sharpened! And 8.5 of the drill bit can not drill through, because the drilling side of the two cutting edges did not grind out (front angle is lower than the back angle, resulting in non cutting! To grind to the rear corner, lower than the front corner!!!!!!!!. When the drill bit blade grinding, drilling 4mm angle, is very fast, also don't add coolant! (head color change, drill when there is a cry, two sides do not chip out, all the drill bit did not wear well), grinding drill bit is a learning, learning is not difficult. Learn to grind the drill bit and drill around with the 10mm to see the edges.
Q:Sharpening of drill angle when machining different materials
For the sharpening of the drill, we should grind the drill at different angles according to the needs of the drilling. For example, a bit of drill bit drilled to a relatively hard material can grind larger (i.e. flat);
