As the largest manufacturer and exporter of building materials in China, we avail ourselves of this opportunity to approach you for mutual-beneficial cooperation. If you want to know more, pls contact me freely.

Q: How do the new pros and cons drill the drill bit without the key?: There are two ways to unload and unload manually:Methods: hand unloading drill drill handle on the ground, pine along the direction of the drill bit to find a hard thing with the hammer hit, the release, remember that it is right to bear left loose, otherwise it will be more and more tightly card.The method of using a card or key to pry it open:(1) card: the electric drill is lifted and the clasp is removed to remove the drill bit;(2) bevel key: remove the bit by pressing the key with an anti clockwise ring, then the drill ring can be taken out.

Q: What drills do we use to drill jade?: Process for drilling holes on the jade carving is the use of drilling needle method, with a needle, rotated on the jade carving, jade sand "," to grind a shallow pit on the surface, then the pit, until the jade material wear. The drilling period "jade sand" has been in the pit with rotating rubbing hole wall, so the upper hole than the lower part to bear "jade sand" friction, so that by this method to hit the hole, the hole is small in shape.

Q: Tap 10 taps, what size drills do we use?: In general, with nominal diameter equal to the diameter of the bottom hole pitch reduction. 10-1.5=8.5, that's 8.5. However, if the quarterly demand is high, follow the formula below:D1=d-5H/8 H=0.866p:D1-- drilling diameterD - thread diameterH - theoretical height of threaded teethP - pitch

Q: 8mm iron expansion bolts with few drilling drill mm?: 8mm iron 12mm impact drill drilling expansion bolt, this is because the expansion bolt is normal, the bulk of the direction of 11MM, so we must use 12MM bit, if the use of a small number of bits, the expansion bolt is difficult in the walls, attention should be paid attention when the fastening nut screw slip.

Q: What are the tools, drills, and any of the machine tools made of?: (1) tungsten cobalt carbide, whose code name is YG, consists of CO and wc. Commonly used brand machine tools, bending strong, not afraid of impact, but hardness and heat resistanceIts characteristics are: good toughness, high bending strength, not afraid of impact, but low hardness and heat resistance. Applicable to the processing of cast iron, bronze and other brittle materialsThe commonly used grades are YG3, YG6, YG8 and so on. The latter figures indicate the percentage of cobalt content. The higher the cobalt content, the better the performance of the impact resistance. Therefore, YG8 is often used in rough machining, and YG6 and YG3 are often used in semi finishing and finishing.(2) tungsten titanium carbide, whose code name is YT, consists of WC (tungsten carbide), Tic (Tan Huatai) and CO (cobalt). Commonly used grades are YTl5, YT30 and so on. Its characteristics are: hardness of 89 ~ 93HRA, heat-resistant temperature of 800~1000 degrees; wear resistance and oxidation resistance are higher; but flexural strength and impact toughness are lower. Suitable for processing carbon steel, alloy steel and other plastic materials.Join titanium carbide can increase the wear resistance of the alloy, alloy and plastic materials can improve the bonding temperature, reduce tool wear, can also increase the hardness; but more brittle, poor toughness, performance under impact is also poor, generally used for processing plastic materials. Common brands are YT5, YT15, YT30, digital is behind the percentage content of titanium carbide, titanium carbide content is higher, the red rigid; but the corresponding cobalt content is lower, the worse the more toughness, impact resistance, so YT5 is commonly used in rough machining, YT15 and YT30 are commonly used in semi finishing and finishing processing.

Q: Why can't the tap be nitrided? Drill bits are available.: Many imported taps are coated now. In addition to TiN, there are TiCN, TiAlN.

Q: What does the cutting depth of the drill mean 3D?: That is, the diameter ratio of the drill, such as 3D, and the diameter of the drill is 20MM, the effective drilling depth is 60MM

Q: How much bit should we use to punch the M5 hole? Tapping with Duodasi attack? Why use 8.3 drill bit in the hole of M10? How do you know how big it is to punch and tap?: If the material soft bottom be slightly smaller, so hard to be slightly larger. As the aluminum tapping hole to drill small, alloy steel tapping will be slightly larger. M5 has a pitch of 0.8, so use 5-0.8=4.2's drill. The pitch is 1.5 M10, normal use 8.5 bit, if 8.3 words may be used as the material of soft, normal bit will lead to larger hole.

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: The whole alloy drill often breaks: Drilling with carbide drills is the most afraid of bit feed instability, vibration and pulsation, which is the most likely to break the drill bit. If the drilling is not guaranteed, the cemented carbide bit can be used instead. The body of this drill is made of tool steel material, but only hard alloy material is inserted in the cutting part. The drill will not break the drill even when it is drilling.
