Product Description
1/2" Drive 400mm Low-Profile Flex-Head Ratchet – Britool Hallmark
Professional Long-Handle 72-Tooth Sealed-Head Ratchet
The Britool Hallmark 1/2" Drive 400mm Low-Profile Flex-Head Ratchet is a professional-quality long-handle ratchet designed to provide excellent leverage, improved access and smooth operation for demanding automotive, mechanical and workshop applications.
Featuring an extra-long 400mm handle, this ratchet provides increased leverage and reach compared with a conventional-length 1/2" drive ratchet, making it particularly useful when accessing difficult fasteners or tackling tighter fixings.
The low-profile teardrop flex-head improves accessibility in confined spaces, while a flush-mounted forward/reverse selector helps minimise the overall head profile.
Inside the head is a precision 72-tooth ratchet mechanism, providing a fine 5° swing arc for effective operation where handle movement is restricted. A sealed-head design also helps reduce the ingress of dust, dirt and workshop grime into the mechanism for dependable long-term performance.

Extra-Long 400mm Handle
At 400mm overall length, this Britool Hallmark ratchet provides significantly greater leverage and reach than a typical standard-length 1/2" drive ratchet.
The extended handle provides greater mechanical advantage, allowing increased turning force to be applied with less effort. It can also make it easier to reach fasteners located deeper inside engine bays, underneath vehicles or behind surrounding components.
This combination of reach and leverage makes the ratchet particularly useful for demanding automotive and mechanical maintenance.
Low-Profile Flex-Head for Improved Access
The flexible head allows the handle angle to be adjusted relative to the socket, providing greater freedom when working around obstructions.
This is especially useful when a straight approach to the fastener is difficult or impossible.
The low-profile teardrop head further improves accessibility, allowing the ratchet to fit into restricted spaces where a larger or bulkier ratchet head may struggle.
Combined with the long 400mm handle, the flex-head provides excellent versatility when working with awkward, recessed or difficult-to-access fasteners.
Sealed Ratchet Head
Workshop tools are regularly exposed to dust, dirt, grease and grime, all of which can potentially affect a ratchet mechanism over time.
The sealed-head construction helps reduce contamination entering the internal mechanism, supporting smooth operation and dependable performance during regular professional use.
This makes the ratchet particularly well suited to busy automotive and engineering workshop environments.
72-Tooth Mechanism with 5° Swing Arc
The precision 72-tooth ratchet mechanism requires just 5° of handle movement between engagements.
A fine working arc is particularly valuable in confined areas where surrounding components restrict how far the ratchet handle can move.
Rather than requiring a large handle swing, only 5° of movement is needed to engage the next tooth.
Combined with the flexible head, this provides excellent accessibility when working around engines, suspension components, chassis assemblies and other restricted areas.
Flush-Mounted Forward / Reverse Switch
The forward and reverse selector is designed to sit flush with the ratchet head, helping maintain its low-profile shape.
This reduces unnecessary protrusions from the head and helps prevent the selector from interfering with surrounding components when working in confined areas.
Direction can be quickly changed between tightening and loosening without removing the ratchet from the working area.
