History of the Brand

Kielder is a relatively new impact wrench brand that was founded in 2015 by a team of engineers in the United Kingdom. The founders included James Wilson, Sarah Davies, and Michael Jones, who had previously worked for other power tool companies.

The Kielder founders saw an opportunity to create high-quality, innovative impact wrenches that improved upon existing products on the market. They aimed to build tools that combined top-notch performance with intuitive design and technology.

After securing initial funding and putting together a small team, Kielder began operations in early 2016. They started off developing just a couple flagship models of impact wrenches. However, the brand quickly gained a reputation for power, precision, and reliability.

Within a few short years, Kielder expanded their product line to offer a wide selection of corded and cordless impact wrenches. They also began exporting to markets outside of the UK. Today, Kielder continues to focus on innovation and building the best impact wrenches possible.

Key Features

Impact wrenches from Kielder stand out for their well-balanced combination of power, performance, and thoughtful design. Here are some of their notable features:

Power and Performance

Kielder impact wrenches are known for their impressive power and performance capabilities. These tools are designed to deliver high torque for demanding applications while also maintaining control and precision.

The power output of Kielder impact wrenches is measured in horsepower, RPMs (revolutions per minute), and torque ratings. Most models range from 2-3 horsepower with max RPMs of 7,000-8,500. This enables them to generate a tremendous amount of torque, usually between 150-550 ft-lbs depending on the specific model.

Higher horsepower along with higher RPMs allows Kielder wrenches to deliver more impacts per minute. More impacts mean more torque, resulting in faster and easier tightening and loosening of bolts. Their motors are optimized to produce max power while staying cool under heavy loads.

When shopping for a Kielder impact wrench, pay close attention to the torque rating which indicates how much rotational force it can produce. Torque ratings of 150-250 ft-lbs are sufficient for most automotive uses while 350+ ft-lbs are recommended for commercial vehicles and heavy equipment. The power and performance of Kielder tools make them well-suited for professional mechanics and industrial settings.

Maintenance Tips

Proper care and maintenance are crucial for ensuring an impact wrench functions optimally over time. Here are some key tips:

• Keep it clean - Impact wrenches collect dirt, dust and debris during use. Regularly blow out the motor with compressed air or use a soft brush to remove particles. Avoid using water or harsh chemicals for cleaning.

• Inspect the anvil - The anvil is the square drive at the end of the impact wrench that fits the socket. Check for wear or damage. Replace a worn anvil to ensure a tight socket fit.

• Lubricate - Sparingly lubricate any moving parts and bearings with light oil. Avoid over-oiling. Refer to the user manual for lubrication points.

• Check the brushes - Inspect the carbon brushes that conduct power in the motor. Replace worn brushes for optimal performance.

• Examine the cord - Check the power cord for any cuts, exposed wires or damage. Replace cord immediately if compromised.

• Change gear oil - For impact wrenches with enclosed gear sets, change oil periodically as specified. Keeping gear oil fresh reduces wear.

• Replace grease - For impact wrenches with open gear ends, regrease gears regularly per the manual. Fresh grease protects gears.

• Inspect sockets - Check that impact sockets are not cracked or damaged. Damaged sockets can break under torque or slip off.

Proper maintenance as described in the user manual is key for an impact wrench operating at peak performance for years.

Accessories

Impact wrenches like Kielder require some additional accessories for optimal performance and longevity. Here are some of the most useful accessories to consider:

Batteries

Cordless impact wrenches run on lithium-ion batteries. Having 1-2 spare batteries fully charged allows you to swap them out when the first battery runs low on power. Look for batteries that offer long runtimes and short charge times. The batteries should be designed specifically for your Kielder model to ensure proper fit and operation.

Cases

A sturdy case is essential to protect your impact wrench and batteries when storing and transporting them. Hard plastic cases that are weatherproof and have customizable foam inserts work best. Make sure the case has enough room for all your batteries, chargers, sockets, and any other accessories. Some cases even have wheels for easy mobility around a shop or job site.

Extensions

Extensions help add reach to get into tight spaces. Look for impact rated extensions made of durable chrome vanadium steel. Rubberized coatings provide a non-slip gripping surface. Flexible extension bars allow accessing fasteners at odd angles. Get a set with multiple length options. Using too long of an extension can reduce torque and power.

Customer Reviews

Kielder impact wrenches are highly rated by customers for their power and durability. Many users mention how impressed they are with the torque these tools can generate, making them ideal for tasks like loosening rusty bolts or lug nuts.

The wrenches receive consistently high ratings across retailer sites, with most models averaging 4+ stars out of 5. The Kielder KWT120 has a 4.7 star average based on over 500 reviews. Customers praise its "unmatched power" and ability to tackle "the toughest jobs".
