Description
Edma depth stop + bit for drywall screws with magnet turns a screwdriver into a tool optimised for drywall screwing and speeds up installation significantly. The integrated depth stop always drives screws to the right depth, and when the target depth is reached, the stop clicks audibly. After the click, the stop prevents the screw from going any deeper, even if the drill is not stopped, which eliminates the risk of overtightening and keeps the face paper intact.
The magnetic hold makes it easier to start the screw, especially overhead and in tight spots. The product is supplied with a removable/replaceable PH2 bit, which makes maintenance straightforward. Designed for professional use where repeatability, speed and a neat finish are decisive.
The product is supplied with a removable PH2 bit that is easy to replace as it wears. This extends usability and reduces maintenance costs. The reverse function allows controlled removal of screws without unnecessary damage to the board.
The compact design and light weight (approx. 0.07 kg) of the stop make it pleasant to use even in cramped spaces. It fits common drills and screwdrivers, and works with drywall screws used on both timber and steel battens.
The product is designed for professional use where repeatability, a neat finish and installation speed are key requirements.
Intended use
-
Fixing plasterboard to the frame (timber/steel): The depth stop ensures that the screw is countersunk to exactly the right depth, so the face paper does not tear and the filler keeps its adhesion. This reduces finishing work and improves the repeatability of the overall quality, especially in wall and ceiling structures. The magnet makes it easier to position the screw and shortens the cycle for each fixing point.
-
Ceiling work and overhead screwing: The magnet minimises screws dropping and makes one-handed work easier. The stop collar acts as a mechanical depth stop, which helps keep the countersinking even in awkward working positions and so reduces the time spent correcting errors.
-
Repair and maintenance work: With the reverse function, incorrectly fitted or overtightened screws can be removed in a controlled way. The replaceable PH2 bit allows wearing parts to be renewed quickly, so work is not interrupted and costs stay under control.

Edma depth stop: instructions for use
-
Fitting to the tool: Fit the depth stop in the chuck of the screwdriver. Make sure the PH2 bit is locked correctly and the magnet is clean of metal dust.
-
Settings: Practise a few test screws in a board to get the right feel.
-
Screwing: Place the screw on the bit; the magnet holds it in place. Press the collar against the board and screw until the stop halts the travel. The screw sits just below the paper surface in a controlled way.
-
Correction: Use the reverse function to remove incorrectly fitted screws. Avoid excessive force so that the board is not damaged.
-
Maintenance: Replace a worn PH2 bit with a new one. Clean the magnet regularly and check that there is no plaster dust in the collar that could affect the depth.
Warnings
-
Use only for the applications the product is intended for (drywall screws, PH2).
-
Avoid too high a speed; it can reduce depth accuracy and tear the paper.
-
Keep fingers and clothing away from rotating parts. Wear safety glasses and, if necessary, ear defenders.
-
The magnet can affect magnetic cards or sensitive devices; store it separately.
