Description

1/4-Inch Medium Pneumatic Die Grinder, 22,000 RPM Variable Speed

Brief Overview

This medium-duty pneumatic die grinder delivers 22,000 RPM variable-speed performance in a compact, vibration-dampening design. The rubberized polymer body provides thermal insulation and reduces operator fatigue during extended use—a significant upgrade over traditional all-metal housings. The safety lever throttle and rear exhaust port offer precise speed control and improved ergonomics for detailed finishing work. Pair this grinder with complementary low-noise pneumatic tools or high-speed variants to build a complete finishing station that serves multiple application tiers.

Key Features

  • Variable Speed Control: Adjustable throttle lever for precise RPM management from idle to full 22,000 RPM
  • Polymer-Reinforced Body: Rubberized overmold absorbs vibration and insulates against cold metal housing—reducing operator discomfort and improving control
  • Standard 1/4" Collet: Accepts common carbide burs, mounted stones, mini drum sanders, and polishing attachments
  • Optional Collet Sizes: 6mm, 1/8", and 3mm configurations available for specialized applications
  • Rear Exhaust Design: Directs exhaust away from workpiece and operator
  • Safety Lever Throttle: Hinged metal trigger with safety features and integrated CE/pictogram markings
  • Compact Form Factor: 45mm width enables access to tight work areas
  • 12-Month Warranty: Full manufacturer coverage included

Business Advantages for Resellers

Margin & Turnover: The variable-speed feature appeals to precision shops that need single-tool versatility—reducing customer SKU pressure on your inventory. The rubberized body design is a premium upgrade that justifies higher margins versus basic metal competitors.

Shop Stickiness: Die grinding is a core operation in automotive, aerospace, and moldmaking shops. This tool's ergonomic design and speed control reduce operator complaints, leading to repeat orders and word-of-mouth referrals.

Application Breadth: One grinder handles deburring, flash removal, finishing, and polishing—widening your addressable customer base across job shops, tool & die facilities, and small manufacturing.
