Product Advantages and Features
I. Core Advantages
Industrial Brushless Motor
Delivers sustained high torque output (up to 120N·m) for processing hard materials like steel and cast iron.
No carbon brush wear, 3x longer lifespan than traditional motors with minimal maintenance.
20V High-Capacity Battery System
Supports 4 hours of continuous heavy-duty operation (tested under full load conditions).
Fast-charging technology enables 80% charge in 40 minutes.
II. Professional Performance
Precision Torque Control
24-stage torque adjustment + mechanical auto-stop clutch ensures tapping accuracy with <0.1mm error.
Electronic overload protection prevents damage to workpieces and tools.
Dual-Mode Power System
Low gear (0-550 RPM) for heavy-duty tapping and high-torque applications.
High gear (0-1800 RPM) for efficient drilling in stainless steel, aluminum alloys, and composites.
III. Durability Engineering
All-Metal Gearbox
Carburized steel gears provide 50% higher impact resistance than standard gears.
IP54 rating ensures protection against workshop dust, coolants, and oil splashes.
Ergonomics & Visibility
Magnesium alloy body (1.8kg net weight) reduces operator fatigue during extended use.
360° surround LED lighting eliminates shadows in complex machining areas.
IV. Professional Accessory System
Industrial-Grade Tool Kit
Includes 32 specialized tools: HSS-G cobalt drill bits, taper taps, and rigid sockets.
Compatible with BT30/BT40 tool holder systems for quick changes.
V. Application Scenarios
CNC machining center tool adjustment and maintenance.
Deburring, mold repair, and production line fastening tasks.
Drilling/tapping in multi-material applications including hardened steels and non-ferrous metals.
