Two-Speed Adjustment Function:
Low Speed Gear: High torque, low speed, suitable for screwing, fastening screws, or working on hard materials like metal to prevent slipping or stripping.
High Speed Gear: Low torque, high speed, suitable for quickly drilling into softer or moderately hard materials such as wood, plastic, or tiles.
Multi-Mode Switching: Most two-speed drills also integrate three modes-screwdriver/drilling/hammering-switchable via a knob or slide switch to adapt to different materials and task requirements.
Stepless Speed / Multi-Gear Torque Adjustment:
The trigger supports speed control based on pressure applied (stepless speed), allowing precise operation.
Torque usually has 10–25+ adjustable levels to prevent damage to workpieces due to excessive torque (e.g., stripping self-tapping screws).
Battery and Endurance:
Mostly designed with lithium batteries, common voltages include 12V, 16.8V, 21V, balancing portability and power.
High-end models are equipped with intelligent BMS battery management systems to improve endurance and safety.
Ergonomic Design:
Non-slip rubber grips, optimized center of gravity (located below the palm), and single-hand operation-friendly design reduce fatigue during long-term use.
Some models come with LED auxiliary lights, electronic speed control modules, and one-key forward/reverse functions.
Chuck and Compatibility:
Most use 13mm or 10mm chucks, supporting quick installation and removal of drill bits; some high-end models use four-jaw steel chucks for improved concentricity and clamping force.
High-quality models support accessory expansion (such as angle grinders, mixing heads, etc.).
