Key Features
Gearless Direct Power Transfer: Removes traditional bevel gears for direct spindle coupling, eliminating friction and power loss to maximize torque efficiency.
Active Electronic Braking: Halts the rotating disc in under 2 seconds upon trigger release, minimizing operational hazards in fast-paced environments.
Anti-Kickback & Overload Protection: Automatically cuts power during sudden disc binding or severe overloads, protecting both operator and motor architecture.
G2.5 Precision Dynamic Balancing: Precision-balanced internal rotors minimize operational vibration, reducing hand-arm vibration syndrome (HAVS) risks during multi-shift work.
OEM/ODM
Custom Branding & Aesthetics: Support for private label laser engraving, silk-screening, and Pantone-matched housing colors to align with your corporate brand identity.
Packaging Solutions: ISTA-certified drop-tested export packaging, including custom blow-molded carrying cases (BMC) with tailored accessory compartments.
Supply Chain Reliability: Documented monthly production capacity exceeding 20,000 units, backed by a stable 30–35 day lead time for standard repeat orders.
Industrial Applications
Heavy Metal Fabrication: Ideal for continuous, high-intensity cutting of thick structural steel, carbon steel plates, and preparation of heavy weld joints.
Foundry & Casting Clean-up: Efficiently removes stubborn burrs, flash, and parting lines from iron and steel castings in high-dust, rigorous environments.
Pipeline Construction & Maintenance: Provides dependable, constant-speed performance for demanding site work, pipe beveling, and heavy surface conditioning.
Shipbuilding & Offshore: Built to tackle aggressive stock removal, rust stripping, and weld blending on large-scale marine structures.
Quality Assurance
European Market: CE-certified (Machinery Directive 2006/42/EC), fully compliant with RoHS and REACH substance restrictions.
North American Alignment: Critical electrical and thermal components source from UL/ETL-recognized supply chains.
Documentation Support: Comprehensive test reports, including noise emission (EN 60745) and vibration magnitude data, are readily available for importer compliance audits.
Packaging & Logistics
Transit Protection: Engineered with custom-molded pulp or high-density EPE foam interiors to secure direct-drive assemblies during global shipping.
Logistics Data:
- Unit Weight (Bare tool): 1.25 kg (Lighter due to gearbox elimination)
- Master Carton (10 units): 42 x 28 x 22 cm | Approx. 14.5 k
Fulfillment Flexibility: Supports palletized sea freight container loading and direct dropshipping models.

Frequently Asked Questions
Q: What is the main advantage of direct drive over gear-driven models?
A: Direct drive eliminates the bevel gear stage, which is the primary source of mechanical wear, heat generation, and power loss. This results in higher efficiency and lower maintenance.
Q: Does the unit require periodic lubrication?
A: No. The absence of a gear box means there is no requirement for internal lubrication or grease replacement.
Q: What level of vibration should operators expect?
A: Our rotors are dynamically balanced to G2.5 standards, resulting in vibration levels significantly below the threshold for standard EN 60745 industrial requirements.
Q: Are these grinders suitable for continuous heavy-duty use?
A: Yes. The optimized thermal management system and brushless motor are designed specifically for high-duty cycle applications such as steel fabrication and shipbuilding.
Q: What safety features are included?
A: Units are equipped with an active electronic brake, an anti-kickback sensor, and a restart protection switch to prevent accidental activation after a power cut.
Q: Can you support custom branding or color schemes?
A: Yes, we offer full OEM/ODM services, including logo integration, Pantone-specific casing, and custom tool box packaging for wholesale partners.
Q: What is the standard lead time for bulk orders?
A: Standard production lead time is 30–35 days from order confirmation. Safety stock is maintained for repeat orders to ensure faster fulfillment.
Q: Do you provide spare parts support?
A: We provide a comprehensive spare parts list for all models and maintain availability for critical components for a minimum of 5 years after the product production cycle ends.
