How to Cut Drywall on a Wall
Wall-mounted drywall cutting has gotten complicated with all the technique debates, tool options, and clean-cut requirements flying around. As someone who has cut drywall in every situation, I learned everything there is to know about getting precise cuts. Today, I will share it all with you.
Basic Techniques
Probably should have led with this section, honestly—the right technique depends on the cut type:
- Straight Cuts: Score with utility knife, snap along line
- Electrical Boxes: Mark location, cut with keyhole saw
- Circular Holes: Rotary tool or hole saw
Tools Needed
That’s what makes proper tool selection endearing to us drywall installers:
- Utility knife with sharp blade
- T-square or straightedge
- Keyhole saw (jab saw)
- Rotary cutout tool
- Pencil for marking
Scoring and Snapping
- Mark cut line on face
- Score deeply along line with utility knife
- Support sheet and snap away from scored side
- Cut backing paper with knife
Cutting for Outlets
- Measure box location from reference points
- Transfer measurements to drywall
- Plunge keyhole saw through face
- Cut along marked lines
Tips for Clean Cuts
- Keep utility knife blade sharp
- Use firm, consistent pressure when scoring
- Make multiple light passes rather than one heavy pass
- Support drywall to prevent breakage
