- Q: What's the difference between a twist drill and an impact drill?
- A twist drill is a tool for cutting round holes in a workpiece by rotating it in a relatively fixed axis. It is named because of its shape of spiral groove. The spiral groove has 2 grooves, 3 grooves or more grooves, but the 2 groove is the most common. The twist drill can be held in manual, electric, hand-held drilling tools, or drilling machines, milling machines, lathes and even machining centers. Drill materials are generally high speed tool steel or carbide.
- Q: Why is the drill hole drilled out of the hole triangular?
- The drilled bit drilled out of the hole was triangular because:The center grinding deviation of the drill is also different from the sides. The drill material with large drilling thickness is big bore, and the drill plate appears triangular hole. The best drill bit is three edged thin grinding tip, smooth drilling burr less. Therefore, the first grinding drill, you need a master demonstration.
- Q: The basic angle of twist drill
- The helix angle, the beta helix angle, is the angle between the most outer spiral line of the drill bit spiral groove and the axis of the drill bit. Since the lead of each point in the spiral groove is the same, the helix angle of the drill bit at different diameters is different, the helix angle at the outside diameter is the largest, and the closer the central helix angle is, the smaller the helix angle is. Increasing the helix angle increases the rake angle, which is beneficial to chip removal, but the drill bit stiffness decreases. The spiral angle of a standard twist drill is 18 to 38 degrees. For smaller diameter bit, the spiral angle should be smaller to ensure the rigidity of the drill bit.
- Q: How can we change an ordinary drill bit into stainless steel?
- I've never heard of it, but it seems to be a high-speed steel drill, and it's not expensive. Why do you charge for that?
- Q: Want to buy a hammer, with the decoration of the house, how much more appropriate aperture
- Must choose the hammer with speed switch. Touch switch when speed is low, can help smooth the drilling machine (for example, on the surface of ceramic tile on the smooth drilling, can not only prevent the bit slip, also can prevent drilling, rupture) during normal operation can be used to ensure high working efficiency.
- Q: How can the 1 millimeter drill be worn?
- The "cutting edge" here is the main cutting edge, and students often turn the top and bottom of the mill into "up and down" when they are grinding. The workers who have been working for more than ten years have been working for more than ten years." This action is also important in the sharpening of the drill, and confidence determines power. When drilling. To master the methods, repeatedly "less grinding" test drilling and the appropriate grinding on the horizontal edge, chip is normal, this is very important, must let students stand in automatic hand grinder, is reading books on the knowledge, otherwise it will make the blade blunt, more understanding. The common standard twist drills only have two main flank surfaces, a grinding edge, a transverse edge, an oblique angle, and two main cutting lengths. In a stable consolidation formula, grinding twist drill is also a lot of bad. Students will find that sharpening a certified standard twist drill is not difficult and much more analytical. To remind students to remember a commonly used piece of 30 degrees." This is the slow grinding of the entire flank from the edge of the bit. A formula and formula two refers to the relative position of the grinding before, to adjust the size of the pressure. You can use a large angle bit and another small angle drill students in the test bench drill drill, the drill bit in drilling process of quick cutting, students can quickly grasp the right edge of the twist drill grinding method, 60 degree students, easy to master. It is easy to dissipate heat and grind. After mastering the methods and techniques, but after sharpening, you must ensure the vertex angle
- Q: What size drills and taps are required for drilling M10's internal threads?
- Internal thread drill M10 should choose the drill and tap should take into account the thread pitch. If you are a standard thread M10*1.5, thread holes should be used with 8.5 bit;
- Q: How long the hand-held electric hammer drill
- Hammer is portable!Electric hammer drill know there are 1.2 meters, the longest not seen don't know
- Q: M6 screws should drill big holes
- M6 screw, installation of air hit 6.5~7 mm in diameter was 5 mm drill tapping hole.After the general drilling drill hole due to beating, slightly more.
- 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);
