Power Tools — FAQ
What torque rating do I need for drilling metal?
For thin sheet metal, 300-400 in-lbs suffices. For steel plate and structural metal, choose 600+ in-lbs. Hardened steel demands 800+ in-lbs or hammer function to prevent stalling.
Is a brushless motor better for metal drilling?
Yes. Brushless motors deliver 50% more runtime, maintain speed under load, and run cooler—critical advantages when drilling metal that taxes motor performance.
Do I need a hammer drill function for metal work?
Hammer function helps with hardened steel, stainless steel, and thick plate. Standard drills work for aluminum and soft steel, but hammer drills prevent bit burning on tough metals.
What chuck size is best for metal drilling bits?
1/2-inch chucks accommodate larger bits for structural steel. 3/8-inch chucks work for most metal bits but limit maximum size. Metal chucks are mandatory for secure bit grip under torque.
How long will batteries last when drilling metal?
Expect 30-50% less runtime than wood drilling. A 2.0Ah battery drills 20-30 holes in 1/4-inch steel; 4.0Ah batteries double that. Keep spares charged for continuous work.
Can I use the same drill bits for metal and wood?
No. Metal requires HSS (high-speed steel) or cobalt bits with 135-degree split points. Wood bits lack the hardness and point geometry, causing walking, breaking, and poor holes.
