Q:What's 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:How to distinguish between electric hammer drill bit used
Hard alloy electric hammer drill body made of high quality alloy steel, the knife head is welded with hard alloy. Matched with various electric machine, concrete, brick and other building materials for hard drilling. The utility model is a drilling tool with wide use and high efficiency in the construction and installation industry.Electric hammer drill set specifications: 5*110mm, 6
Q:How do you tell which materials are used in the test?
The drill shall be selected according to the material properties of the material to be machined. For example, stainless steel uses cobalt cobalt drills. Use tungsten cobalt alloy bit when producing high heat when the bit is cutting
Q:What's the difference between an impact drill or an ordinary electric drill?
An electric drill is a drilling machine that uses electricity as power. Is the power tools in the conventional products, but also the largest demand for power tools products. The electric drill is only available in the form of rotation, especially for drilling on materials that require little force, such as cork, metal, brick, tile, etc.. Just rely on the electric motor drives the drive gear to increase the strength of the drill bit rotation, do scraping in metal, wood and other forms of perforated material.
Q:What size drills are we going to use to drill the holes in the M7 and with the larger twist drills?
The common thread M7 second series, not commonly used, the coarse thread pitch according to the national standard of 1mm, therefore, the bottom of the thread holes at the 6mm, actually should be: the bottom hole diameter of =7-1.06p, where p is the pitch, calculated 5.94mm, underport with 6mm drill bit, not too bad. After drilling, tap with M7 tap.
Q:What is the drill bit of the percussion drill, please?!
The diameter of the drill is in units.
Q:Why not hammer drill iron? yes or no?
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 causes the drill bit to break at the end of the hole?
Small bit not used high speed, with small feed amount.A small drill can withstand torque is small, the use of high speed with a small amount of feed, can reduce the small rotating cutting output, so as not to drill to bear large torque.
Q:Deep hole refers to the diameter of drill bits more than times, called deep hole
DF deep hole drilling: this kind of drill absorbs the advantages of BTA deep hole drilling and jet drilling, and uses single pipe, chip removal, pushing and suction to improve the chip removal ability, and can drill holes at the depth of 8 millimeters or more. Gun drills are usually made of high speed steel or hard alloy. Various kinds of inner chip removing deep hole drilling can be welded or mechanically clamped and indexable carbide inserts according to size. The guide block on the deep hole drill has the function of guiding and centering to reduce the deflection of the drill hole and the vibration during cutting. The arrangement of cutter teeth and guide blocks in deep hole drilling mainly considers the balance of radial forces during chip separation and cutting. The cutter body and the drill rod can be welded or square threaded.
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.
