Why This Tool Matters for Your Reseller Business

Shop Compatibility: At 113 L/min air consumption, this grinder integrates seamlessly into standard shop compressor setups (15–25 HP compressors common in most facilities). No special infrastructure required.

Operator Satisfaction: The 79 dB(A) noise level keeps mechanics and technicians comfortable during shifts—low vibration (2.5 units) means reduced wrist strain and higher accuracy for detail work.

Margin-Friendly Category: Pneumatic hand tools remain high-velocity SKUs in professional shops. Mechanics replace them frequently due to wear, making this a reliable repeat-purchase item for your customer base.

Lightweight & Portable: At just 0.75 kg, technicians move between workstations without fatigue, increasing adoption rates.
