What I know about the drill chucks

Commonly used drill chucks mainly include key-type drill chucks and keyless drill chucks. The parts of key-type drill chucks are mostly produced in large quantities by machine tools, so the price is relatively low. However, due to the limitation of its own structure, The precision of the key-type drill chuck is not high, and it is mainly used in occasions where the clamping precision is not high, such as bench drilling machines, small radial drilling machines, electric tools, etc. In addition, the loading and unloading of the drill bit needs to be tightened with a wrench, and the operation is more complicated. In the machining center, For high-precision drilling machines and other occasions that require high drilling accuracy, self-tightening drill chucks are generally required.

There are two types of drill chucks on the market today. One is the key-type drill chuck, They all manually input the clamping force to clamp the drilling tool. Key-type drill chuck can also be divided into heavy, medium and light. The other is Keyless drill chuck. It can automatically increase with the increase of clamping force required during drilling. In terms of price, the light wrench drill chuck, the heavy wrench drill chuck, the hand tight drill chuck and the self-tightening drill chuck increase in turn. The difficulty in processing technology is also more difficult in turn. In the market share, hand-tightening drill chucks account for more than 60%, light and heavy ones are used more, and self-tightening drill chucks are used least. The reason is that the price is expensive. We can only see him in military industry and important equipment, which is less than 1% of the weight.

Advantages of keyless drill chuck

1. High precision, high clamping;
2. With self-tightening function, the drill bit can be slightly clamped, and the clamping force will increase synchronously with the increase of torque in the drilling, and can produce obvious high-strength clamping force, thus preventing the drill bit from slipping;
3. Hardening treatment of vulnerable parts;
4. Taper holes can be used with various drill handles.                                                                                                                                                                                                                                                                                                                                                                                                                                         If you have more insights about the drill chuck, you can communicate with us
