Couldn't load pickup availability
The Britool Hallmark 1/2" Drive Heavy Duty Breaker Bar is a professional-grade 750mm / 29.5" long power bar designed to provide substantial leverage when loosening stubborn and seized fasteners.
Manufactured from high-quality Chrome Vanadium steel and heat treated for increased strength, this heavy-duty breaker bar is built for demanding automotive, mechanical, engineering and workshop applications.
The extended 750mm handle provides significantly greater leverage than a conventional short breaker bar, helping users apply high torque with less physical effort.
Its 180° flexible head allows the bar to be positioned at different angles, improving access around vehicle components and making it easier to work in confined or awkward areas.
The heavy-duty head design is substantially stronger than traditional breaker bar constructions where the knuckle is held between two ears with a retaining screw. This robust design is engineered to withstand torque loads of up to approximately 1862Nm.
A spring-loaded ball bearing socket retainer helps keep the socket securely attached during use.

Heavy-Duty Head Design
Unlike conventional breaker bars where the drive knuckle is commonly retained between two ears with a screw, this Britool Hallmark model uses a reinforced heavy-duty head design intended to withstand substantially higher torque loads.
The design is particularly useful when tackling:
- Seized nuts
- Stubborn wheel fasteners
- Suspension components
- Chassis fasteners
- Engine and transmission components
- Heavy automotive repairs
- Commercial vehicle maintenance
- General workshop applications
The long 750mm handle provides excellent leverage without requiring an excessively large amount of physical force.
180° Flexible Head
The breaker bar features a 180-degree pivoting head, allowing the user to position the handle according to the available working space.
This flexibility can be particularly useful when working around:
- Vehicle suspension
- Engine bays
- Wheel hubs
- Chassis components
- Restricted workshop access
The pivoting head allows better positioning compared with a completely fixed breaker bar.
Socket Retention
A spring-loaded ball bearing on the 1/2" square drive helps retain the socket securely during use.
This provides a positive connection between the breaker bar and compatible 1/2" drive sockets while still allowing sockets to be changed when required.
Sacrificial Knuckle Design & Repair Kit
The knuckle / drive end is a consumable component designed to break if the breaker bar is overloaded. This helps protect the main body of the power bar from excessive damage.
A replacement service repair kit is available:
LP750HD/RK
The repair kit allows the drive end to be replaced and the breaker bar returned to service.
Please note: The knuckle and repair kit are classed as consumable/service components and are therefore not covered by the manufacturer's warranty.
