Britool LP600B 1/2 Drive Breaker Power Bar 600mm Long 512Nm Heavy Duty

The Britool LP600B 1/2" Drive Breaker Bar, also commonly known as a power bar, is a professional-grade hand tool designed to provide the additional leverage required for loosening tight, stubborn, seized or corroded fasteners.

Featuring a substantial 600mm overall length and professional 1/2" square drive, the LP600B provides significantly greater leverage than a conventional ratchet handle, making it particularly useful for demanding automotive, mechanical, engineering and workshop applications.

The breaker bar incorporates a hinged knuckle head, allowing the working angle to be adjusted to suit the position of the fastener and available working space. This flexible-head arrangement can improve access while allowing the user to position the handle effectively for controlled leverage.

Manufactured from high-quality alloy steel, the LP600B is engineered for demanding professional workshop use and conforms to the stated DIN standard requirements. The breaker bar has a maximum torque rating of 512Nm.

1/2" Square Drive

The LP600B features a professional 1/2" square drive, making it suitable for use with compatible 1/2" drive hand sockets and accessories.

The 1/2" drive format makes this breaker bar particularly useful for automotive servicing, mechanical maintenance and other applications involving larger or more heavily tightened fasteners.

Always use a socket of the correct size and type for the fastener being worked on.

600mm Extra-Long Handle

At 600mm long, the LP600B provides substantial leverage compared with shorter ratchets and conventional socket handles.

The extended handle increases the mechanical advantage available to the user, making it particularly useful when attempting to loosen fasteners that are difficult to move using a standard ratchet.

This additional leverage can be valuable when working with tight, stubborn, seized or corroded nuts and bolts commonly encountered during automotive servicing and mechanical maintenance.

Hinged Knuckle Design

The breaker bar incorporates a hinged knuckle head, allowing the angle between the handle and socket to be adjusted.

This provides greater flexibility when approaching fasteners in different positions and can make it easier to achieve an effective working angle where surrounding components restrict access.

Unlike a ratchet, a breaker bar does not rely on an internal ratchet mechanism to transmit torque. This makes it particularly suited to the initial loosening of stubborn fasteners before changing to a ratchet or other appropriate hand tool.

512Nm Maximum Torque

The Britool LP600B has a stated maximum torque rating of 512Nm, providing substantial capacity for demanding professional hand-tool applications.

The maximum torque rating should not be exceeded, and the breaker bar should always be used with appropriately rated sockets and accessories.

For applications requiring a specified final tightening torque, use an appropriate calibrated torque wrench rather than a breaker bar.

Professional Automotive & Workshop Applications

The Britool LP600B is suitable for demanding professional applications including:

• Automotive servicing and repairs
• Wheel and hub related maintenance
• Suspension and chassis work
• Engine and drivetrain repairs
• Commercial vehicle maintenance
• Mechanical engineering
• Machinery servicing
• Professional garages and workshops
• Fleet maintenance
• Industrial maintenance
• General heavy-duty fastener removal

Replaceable Knuckle – LP600/RK Repair Kit

The hinged knuckle assembly is considered a consumable component and is therefore subject to wear during the working life of the breaker bar.

A replacement Britool LP600/RK knuckle repair kit is available separately, allowing the knuckle assembly to be replaced when required rather than automatically replacing the complete breaker bar.

This is particularly useful in a professional workshop where the LP600B may be subjected to frequent use.

The Britool Hallmark Range

The Britool Hallmark range was developed by Britool in the 1980s for the automotive aftermarket and has been a long-established choice for professional workshop users.

Each tool carries distinctive Britool Hallmark branding,, providing clear identification and reflecting the professional tooling heritage of the range.

The Britool Hallmark guarantee covers defects in materials and/or workmanship when tools are used for the purpose for which they were designed and for their expected service life.

The guarantee does not extend to fair wear and tear, moving parts such as ratchet mechanisms, or consumable components such as bits, repair kits and the LP600B knuckle assembly.
