10 Best Impact Wrenches in the Philippines 2025 | Flyman, Bosch, and More

If you usually work on your own car, an impact wrench with around 150 to 300 ft-lbs of torque is sufficient. This range easily covers everyday tasks, such as removing lug nuts, replacing basic car parts, or changing brake pads, making it perfect for DIY maintenance, but distinct from the higher torque levels required for professional auto work.

Aside from car maintenance, this level of torque also works well for home projects such as setting up furniture. Lighter models in this category are easier to control and less tiring to use, making them an excellent choice for beginners or casual users.

An impact wrench with at least 400 ft-lbs of torque provides the consistent power needed for daily automotive tasks. This level of strength makes it easier to loosen rusted or tightly fastened bolts, ensuring smoother repairs and fewer delays. With higher torque output, you can work on a wider range of vehicles without straining your tool or your hands, improving both efficiency and durability in professional environments.

For heavy machinery, farm equipment, or construction vehicles, impact wrenches with 600+ ft-lbs are the best fit. High-torque models are built to tackle large, stubborn fasteners that standard tools can’t loosen, making them ideal for industrial-level maintenance and repairs.

These powerful wrenches are designed for continuous use, providing the strength and durability needed for demanding environments. While they can be heavier and bulkier, they offer consistent performance and efficiency when working on large-scale projects where reliability matters most.

A cordless impact wrench powered by rechargeable batteries allows you to move freely between job sites without being tied to an outlet. Their portability also makes them ideal for roadside assistance, mobile repairs, or any job site with limited power access. Most models also utilize lithium-ion batteries that deliver steady power and long runtimes; however, it’s still advisable to keep a spare battery charged, especially when working for extended periods.

Corded impact wrenches plug directly into an outlet, providing continuous power without the limitations of battery life or the need for frequent charging. These units are ideal for workshops or garages where electricity is always available. Although they don’t offer the same portability as cordless models, they are often more affordable and eliminate the need for battery replacements over time.

The 1/2-inch drive is one of the most practical and widely used options, offering a torque range of approximately 300 to 500 ft-lbs, which is suitable for most automotive tasks, such as removing lug nuts, engine bolts, and suspension parts. Its balanced design provides enough power while remaining lightweight and easy to control, allowing comfortable use even during long hours of work.

This drive size is also compatible with a wide variety of sockets, making it versatile enough for tire changes, construction projects, and equipment assembly. Because of this flexibility, the 1/2-inch drive remains a reliable choice in both professional and personal work environments.

A 3/8-inch drive impact wrench is best suited for smaller bolts and tight engine spaces. It’s lightweight, easy to handle, and offers enough torque for light to medium-duty tasks. This makes it especially useful for car maintenance, engine work, or interior assembly, where precision is crucial.

Due to its compact size, a 3/8-inch drive allows for better control, thereby reducing fatigue during extended work sessions. You can use it for removing bolts on alternators, brake calipers, or dashboard panels without worrying about over-tightening or damaging small fasteners.

Drives 3/4 inch and larger are designed for heavy-duty applications, delivering the high torque required to handle large bolts on trucks, construction equipment, and industrial machinery. Their strength and durability make them a common choice in factories where demanding work is routine. These models are constructed with reinforced, impact-resistant materials designed to withstand repeated use and intense force.
