Pinpoint precision

The integrated XPSTM shadow cut line uses a built-in high-intensity LED light to cast the shadow of the blade, allowing users to line up the cut and acting as a virtual pencil mark.

Adjustable Control

Fully adjustable control

Fully adjustable mitre and bevel stops allow for fast, simple angle setting. Added control comes from an adjustable depth stop and a bevel R to L override (49º) giving you the ability to quickly bevel from side to side.

Dust management

superior dust management

The DHS780 is fully AirLock compatible and features an inline dust deflector assembly, with a chute perpendicular to the blade to efficiently drive debris away from the blade and protect users from dust inhalation
