Description

High-Speed Micro Grinder, 30mm Disc, 21,000 RPM, Pneumatic Angle Head

Brief Overview

This pneumatic micro grinder is engineered for precision work requiring exact control and minimal material removal. The 30mm disc and 21,000 RPM spindle speed make it ideal for fine finishing, detailed grinding, and polishing tasks on delicate components. For shops requiring a broader range of finishing capabilities, consider pairing this with a compact 6mm die grinder for ultra-fine detail work or a larger 5-inch disc grinder for heavier stock removal.

Key Features

  • 30mm abrasive disc with M7×0.75 spindle connection for quick accessory changes
  • 21,000 RPM maximum speed delivers consistent, controlled cutting action for precision applications
  • Right-angle head design provides ergonomic access to tight spaces and angled surfaces
  • Lightweight construction at 0.23 kg (0.52 lb) reduces operator fatigue during extended use
  • Low air consumption at 0.5 L/s (1.1 CFM) minimizes compressor demand and running costs
  • Rubberized grip section and chrome-finished head ensure comfortable handling and durability
  • Flexible hose connection with clear tubing allows easy monitoring of material flow

Business Advantages for Resellers

Low Barrier to Inventory: Minimal footprint, lightweight design, and modest air consumption requirements make this grinder an easy add-on to any shop's pneumatic tool lineup without substantial infrastructure investment.

High-Margin Positioning: Precision micro grinding is a specialty service. This tool commands premium resale pricing because skilled operators recognize its value for delicate finishes, polishing, and detail work that larger grinders cannot safely perform.

Essential for Detail-Oriented Shops: Jewelry makers, watch repair, dental labs, model builders, and precision electronics assembly all depend on tools like this. Its specific size and speed profile target a profitable professional segment.

Operator Safety & Efficiency: The combination of low noise (71 dB(A) average) and minimal vibration (0.9 m/s² per ISO standard) reduces fatigue and hearing protection requirements, increasing perceived value to health-conscious buyers.
