Hard alloy woodworking hole opener, also called hinge drill, can be installed in the common electric hand drill charging drill bench drill advertising cnc engraving machine impact drill flat drill function and other machines, machine drill chuck clamping range of 10 mm and above can be used.

Alloy aircraft type adjustable hole opener: this hole opener is suitable for drilling: plastic wood plasterboard three plywood and other materials on the drilling operation, widely used in DIY sound box hole shooting light hole woodworking hole plastic plate hole is a new tool in the decoration industry, suitable for table drill drilling machine all kinds of hand electric drill can also be used manually (no electric drill, but more laborious)

Hard alloy woodworking hole opener can be used for wood products perforation, installation of spherical door tips, drawer tips, plastic products, wood, plywood plastic hinge installation, etc., pay attention to safety when using!

Product drilling is a very common processing technology in hardware manufacturing, many people have their own ideas and understanding of drilling, but there are also some people in the product drilling for the choice of twist drill very distressed, in fact, as long as you can understand the applicability of drill, basically general material drilling can be perfectly conquered, Today Xiaobian to discuss with you is to teach you how to correctly choose a suitable for their own products of twist drill.

A very important characteristic of drilling is that different twist bits should be selected according to different materials. Twist bits are usually divided into two raw materials: high speed steel and hard alloy. The choice of twist bits should be based on the equipment you use and the processing material to determine which kind of raw material twist bit should be selected. For example, if you are a common hand drill drilling and the processing material may be plastic or iron sheet or some relatively easy to process materials, it is suggested that you can choose ordinary high-speed steel twist drill bit, but if you are a lathe drilling equipment or high precision CNC drilling, You can give priority to carbide bits or high quality HSS twist bits.

A very important difference between alloy twist bit and high-speed steel twist bit is that alloy bit is more suitable for the field of high precision machine drilling, because alloy bit has higher precision and higher concentricity. Only high precision CNC, numerical control, lathe and other fields can meet the concentricity requirements of alloy bit. The biggest drawback of alloy twist bit is that its toughness is very poor. If you drill by hand, it is difficult to grasp the concentricity of the alloy bit. When you drill by hand, the phenomenon of instability occurs. Then the alloy twist bit does not have enough toughness and it is particularly easy to break or break the knife.

Although HSS bits are not as hard as alloy bits, and indeed are not as good for some hard-to-cut materials, HSS bits are better suited than alloy twist bits for hand drilling. Although not as hard, the toughness is much stronger than that of alloy bits, and HSS twist bits are generally perfect for most metal materials. Just for some ultra-hard metal material is weaker than alloy twist drill.

Want to choose a suitable for their own twist drill first to understand some of their own conditions such as the use of drill equipment is what kind of CNC or hand drill or bench drill or lathe and so on equipment, in addition to understand the use of drill equipment, followed by the material of the product to be processed, Knowing the material of the product can help you to get the right twist drill bit from the manufacturer when you are looking for it.

During the daily use of the hole opener, relevant maintenance work is needed to ensure that the hole opener can be used normally for a long time. Next 258 platform Xiaobian to introduce the maintenance of the hole opener.

Used hole opener, we want to clean up, the first to remove the hole opener, the internal cleaning, the hole opener inside the waste debris clean, and then the hole opener for installation, followed by the installation of the surface after wiping clean, finally put the hole opener in a suitable storage environment.

After the hole opener installed on the drill can be in copper, iron, stainless steel, plexiglass and other plates flat or spherical surface for arbitrary cutting. Use flexible, convenient, safe. The maintenance of the split hole has the following points:

1. Select the machine that uses high quality to install the hole opener. As an important consumable accessory of the machine, the hole opener will be more conducive to the life of the hole saw only if the horse is equipped with a good saddle.

2. For the use of cutting fluid to correct, appropriate amount. Wood or plastic, gypsum board and other soft materials punching, generally do not need to use cutting fluid, but if it is cutting metal, alloy, ceramic, ceramic tile and other hard and hot materials, you need to add cutting fluid.

3. Choose the right material, choose the suitable cutting hole opener is the most important factor to greatly extend the service life. There is no one belt opener can be suitable for all the opening requirements, and various forms and characteristics of sawteeth have their different utility, to choose suitable cutting material and cutting of the hole opener, the tooth shape and tooth spacing of the hole opener are very important factors.

According to the diameter and total length of the designed bit, an alloy rod cutter or a wire-cutting device can be used for fixed-length machining.

Two flat ends of cut rods of fixed length could be used on hand tool grinders.

Chamfering or perforating on the ground end faces of alloy rods to prepare for grinding the outer diameter and shank of the bit. It depends on whether the cylindrical grinding jig is positive or negative.

Processing the outer diameter of the drill bit, the outer diameter of the cavitation part and the shank part on a high precision cylindrical grinder to ensure the design requirements of the cylindrical diameter, circular runout, surface finish and so on.

In order to improve the machining efficiency in numerical control grinder, chamfering the drill tip can be used before the numerical control grinder is applied to the alloy rod material. For example, the chamfering Angle can be used to rough grind to 142°.

Clean the alloy rod material after chamfering, and transfer to the process of numerical control grinder. All parts of the bit are processed on the five-axis numerical control grinder.

If the drill bit needs to be improved in the size of the sink and the surface finish, it can be polished with a wool wheel and welcome before or after the fifth step. In this case, it must be processed in more steps.

If there are something under the company's brand and the bit's size, a laser is made to mark it.
