Power Tools — FAQ
What makes an oscillating tool better than a drywall saw?
Oscillating tools cut outlet boxes in 30 seconds versus 3 minutes manually. They produce cleaner edges with less dust and work in tight corners where saws cannot reach.
Can I cut drywall with a wood-cutting blade?
Yes, but drywall-specific blades have wider gullets to eject dust faster and hardened teeth to prevent paper shreds. Multi-material blades work in a pinch for occasional cuts.
How deep can oscillating tools cut through drywall?
Most blades cut 1-1/2 to 2 inches deep, easily handling double 5/8" fire-rated drywall. For thicker assemblies, plunge from both sides or use a longer blade.
Should I get corded or cordless for drywall work?
Cordless dominates drywall—no cords to drag through dust and freedom to move room to room. Modern 20V batteries last all day for cutting tasks.
What speed setting works best for drywall?
Use high speed (18,000-20,000 OPM) for cutting, medium (14,000-16,000) for sanding mud, low (10,000-12,000) for delicate corner work or repair patches.
How do I reduce dust when cutting drywall?
Connect a shop vac to the tool's dust port, score the paper facing first, and cut with a slight forward tilt to direct dust down. Some pros spray water mist.
