Cordless Ratchet Wrench
DRW–402L
18V Long-Body Ratchet Wrench
Engineered To Reach.
Built To Loosen.
Many extended cordless ratchets stop at 60-110 Nm. They reach the fastener, then you still need another tool to break it loose. DRW-402L reaches it and loosens it – reach it, loosen it, move on.

The Usual Compromise
More reach usually
costs you power.
More power usually costs you speed. DRW-402L holds all three – reach into crowded engine bays, suspension systems, trucks and agricultural machinery at full 180 Nm, and still run off at up to 300 RPM.
Reach
484 mm Reach
The extended body gets to deeply positioned fasteners a standard-length ratchet can’t reach.
Power
Full 180 Nm
Many extended cordless ratchets stop at 60-110 Nm, so a second tool is still needed. This one breaks the bolt loose itself.
Speed
5 Turns A Second
Up to 300 RPM spins the fastener off fast once it’s broken loose.

Reach It.
Loosen It.
Move On.
One tool covers the whole sequence: get into the tight space, break the fastener loose at 180 Nm, then run it off at up to 300 RPM. No swapping tools mid-job.
Fewer tool changes, less manual effort, faster repair work.

FAQ
Common Questions.
What is the DRW-402L used for?
It loosens and tightens fasteners that sit deep inside crowded engine bays, suspension systems and agricultural machinery, where a standard-length ratchet cannot reach.
Who is this tool best suited for?
Automotive, truck and agricultural machinery technicians who regularly work around difficult-to-access fasteners.
How does it compare to other extended cordless ratchets?
Many extended cordless ratchets published in this class deliver around 60-110 Nm, which reaches the fastener but often still needs a second tool to break it loose. DRW-402L delivers up to 180 Nm.
Does the longer body reduce speed?
No. It still reaches up to 300 RPM – five revolutions per second – for fast run-off once the fastener is free.
What are the speed settings?
Three no-load speeds: 0-150, 0-200 and 0-300 RPM. At the top setting that is five revolutions per second for fast removal once the fastener is free.
Can the torque be adjusted?
Yes. Three selectable torque levels – 100, 140 and 180 Nm – let you match the output to the fastener instead of running at full power on every job.
What battery and drive size does it use?
18 V d.c. with DB-1850P (5.0Ah) or DB-1825 (2.5Ah) Li-ion packs, and a 1/2″ (12.7 mm) square drive rated for M5-M12 bolts.
