12mm Metal drill – What is it ?
A 12mm metal drill bit is a tool used to create 12mm diameter holes in various materials—primarily metal, plastic (PVC/HDPE), or even wood. For drip irrigation, it’s used to drill holes in irrigation pipes to insert emitters, grommets, or connectors.
Step-by-Step: How to Use a 12mm Drill
Use a 12mm high-speed steel (HSS) drill bit if drilling into plastic like PVC or HDPE.If drilling into metal tanks, use a cobalt or titanium-coated bit.
Lay out your irrigation pipe on a flat surface.Use a marker or chalk to mark exactly where each hole is needed. Usually spaced based on plant spacing (e.g., every 30cm or 50cm).
Use pipe clamps, a vice, or a helper to hold the pipe still.This prevents slipping or twisting while drilling.
Insert the 12mm bit into your drill.Set drill to low to medium speed.Position the bit vertically over the mark.Drill slowly and steadily — avoid applying too much force. If drilling plastic, don’t let the bit melt it — pause occasionally to cool. If drilling metal, apply light cutting oil.
Use a deburring tool, utility knife, or even a round file to smooth out the edges.This prevents leaks and makes it easier to insert emitters.
If using a grommet, press it firmly into the hole.Then insert the 12mm barbed emitter, take-off, or dripper through the grommet. You may need to twist slightly to push it in fully.
