" Precision drive makes for smooth performance when removing multiple bolts of the same type. Faces stiff competition from Milwaukee but at the price BISON impact wrench offers a lot of power. For those not requiring more than 250 lb of drive torque, the new BISON BS-1243 12V stubby 1/2 inch drive is a compelling alternative.Sales of this have increased significantly.At the same time, I have not received bad reviews from customers.Nice products.

A holistic solution to your most common questions about BISON impact wrenchs.
Impact wrenches make it easier to remove tough bolts, and fixing bolts and screws will be effortless. This is a tool that looks expensive before you use it. If you buy a quality product, it may last your entire life.
Compared with air or electric impact wrench, air impact wrench has a huge advantage because you will not be restricted by being tied to the air compressor hose or outlet wire. Over the years, battery technology has improved a lot. If you charge the backup battery while the backup battery in the impact wrench is working, you will never run out of power.
Most housework can be done with a smaller impact wrench, but car wrenches usually require more force. A 1/2-inch impact wrench can handle the power required to perform most maintenance on the daily driving vehicle. Smaller 1/4-inch and 3/8-inch impact wrenches are usually used to tighten smaller screws and bolts for building or repairing houses. If you live in a rusty belt or near the ocean, you may want to consider using a more powerful impact wrench. Rusty lug nuts and bolts tend to be tight.
When trying to loosen the nut with an impact wrench, it is not uncommon for the nut to get stuck or overtightened. The impact wrench deforms the nut, causing it to break. Before attempting to loosen it, soaking the jammed nut with penetrating oil will help prevent damage.
The impact sleeve is made of chromium-molybdenum carbide, making it much stronger than ordinary sleeves or manual sleeves usually made of chromium vanadium surface. Fixing the ordinary socket to the impact wrench, you may face the potential danger of the socket breaking.
If you have an air impact wrench, you need an air compressor to use it. Air impact wrenches are particularly suitable for automotive operations because they have high power, light weight, and generally lower cost than electric impact wrenches. The size of the air compressor you need depends to some extent on the size of the impact wrench you use. The most common size is a 1/2-inch impact wrench. To power it, you need an air compressor with a 6-gallon tank and an air compressor with 3.5 to 5 cubic feet per minute (cfm). For a small impact wrench with a 1/4 inch driver, an air compressor with 1 to 2 cfm air flow at 90 psi is sufficient.

An impact wrench is an essential tool when it comes to working on your own car or truck, or when it comes to maintaining household lawn equipment and other machinery. A powerful wrench with a hammering mechanism can provide a powerful and fast blow to loosen stuck nuts; otherwise, you may need strong muscles and breaking hammers to loosen them. The high power and high torque impact wrench provided by BISON can easily take out or tighten the nut, which will make any work faster and easier.
Like many power tools, impact wrenches are divided into three basic types: powered by air, alternating current, or batteries.
Air impact wrench is a standard configuration in auto repair shops, but it is not so popular in-home or DIY use. These tools are powerful, lightweight, and generally cheaper than electric impact wrenches, but require the air compressor to work. BISON pneumatic impact wrench is a professional heavy duty impact tool specially designed for industrial use.
In terms of power, corded electric impact wrenches are ranked second, but limit you to the nearest power outlet. Corded impact wrenches are generally lighter in weight, and they are a good choice for long hours of work. If you work in the garage or yard, then this may be the right choice for you.
Cordless impact wrench is the most popular type for homeowners, DIY, and those who take care of repair as a hobby. Since you are not limited by the power outlet, battery impact wrench can let you perform repairs quickly and easily anytime, anywhere. The wireless design also helps avoid tripping and safety hazards, making it ideal for busy workplaces. The downside is that you need to track battery life, and wireless tools tend to be heavier than the other two styles and have slightly lower power in terms of torque.
Some manufacturers express torque in foot-pound force, while others use inch-pound force. For most basic work, you need more than 200 foot-pounds of torque. Don't think that you need the maximum torque. If the torque is too large, you may often damage the nut. BISON provides a variety of impact wrench models with different sizes and torques, so you can easily find a tool suitable for any job.
The working speed range of the impact wrench is in RPM. Look for a model that has at least 3,000 RPM and allows you to easily change the speed with a trigger.
The "impact" in an impact wrench is an explosion of extra power that increases the strength of the tool's rotation, measured by the amount of impact per minute. Generally speaking, an air impact wrench can provide 2,000 to 3,000 impacts per minute.
You can wholesale impact wrenches separately, but BISON impact wrench kit is a more valuable option. They contain essentials such as durable toolboxes or kits, spare batteries and battery chargers.
You can control the torque output of the wrench this way. This is good because you can reduce the risk of over-tightening the bolt or breaking the bolt head.
not all wrenches are designed equally well in this area. Find a wrench that fits your hand, has a comfortable grip material, and is well-balanced to reduce fatigue and stress during use.
