Edma depth stop + tip for drywall screws with magnet

The Edma Depth Stopper + bit for drywall screws with magnet turns your screwdriver into an optimized tool for drywall screwdriving and speeds up installation big time. The built-in depth stopper always sets the screws to the right depth, and when you hit the target depth, it clicks audibly. After the click, the stopper keeps the screw from going deeper, even if you don't stop the drill, which eliminates the risk of over-tightening and keeps the surface paper intact.
The magnetic holder makes starting the screw easier, especially overhead and in tight spots. The product comes with a removable/replaceable PH2 bit, making maintenance straightforward. Designed for pro use, where repeatability, speed, and clean finishes are key.
The product comes with a removable PH2 bit that's easy to swap out as it wears. This extends usability and cuts down on maintenance costs. The reverse function lets you remove screws in a controlled way without damaging the board unnecessarily.
The stopper's compact design and light weight (about 0.07 kg) make it comfy to use even in tight spaces. It fits common drills and screwdrivers, and works with drywall screws used for wood or metal framing.
The product is designed for pro use, where repeatability, clean workmanship, and installation speed are essential requirements.

Intended Use

Attaching drywall to framing (wood/metal): The depth stopper ensures the screw sinks just right, so the surface paper doesn't tear and the joint compound sticks well. This cuts down on cleanup work and improves overall quality consistency, especially in wall and ceiling setups. The magnet makes positioning the screw easier and shortens the cycle for each attachment point.

Ceiling work and overhead screwing: The magnet minimizes screw drops and makes one-handed work simpler. The stopper collar acts as a mechanical depth stop, helping keep consistent sinkage even in tricky positions, and thus reduces time spent fixing mistakes.

Repair and maintenance jobs: The reverse function lets you remove misinstalled or over-tightened screws in a controlled manner. The replaceable PH2 bit allows quick swaps of wear parts, so work doesn't stop and costs stay in check.

Edma Depth Stopper – User Guide

Installation on tool: Attach the depth stopper to the screwdriver chuck. Make sure the PH2 bit is locked in properly and the magnet is clean of metal dust.

Settings: Practice a few test screws on the board to get the right feel.

Screwing: Place the screw in the bit; the magnet holds it steady. Press the collar against the board and screw until the stopper halts progress. The screw sinks controlled below the paper surface.

Correction: Use the reverse function to remove misinstalled screws. Avoid excessive force to prevent board damage.

Maintenance: Swap out worn PH2 bits for new ones. Clean the magnet regularly and check that no drywall dust in the collar affects depth.

Warnings

Use only on intended targets (drywall screws, PH2).

Avoid too high RPM; it can reduce depth accuracy and cause paper tears.

Keep fingers and clothes away from spinning parts. Wear safety glasses and ear protection if needed.

The magnet can affect magnetic cards or sensitive devices – store separately.
