Description

1-Inch Air Impact Wrench with Pin Clutch Mechanism

Brief Overview

The S-TA1PIS is a robust 1-inch drive air impact wrench engineered for heavy-duty industrial applications requiring consistent, controlled fastening power. The twin hammer mechanism delivers 2400 ft-lbs of torque at 3900 RPM, making it well-suited for demanding automotive service, equipment assembly, and maintenance operations. The pin clutch system ensures smooth operation without sudden shock transfer, reducing operator fatigue and tool wear. This is a complementary option to smaller 1/2-inch impact tools for shops requiring both socket sizes, or a direct upgrade from medium-duty composite wrenches.

Key Features

  • Pin Clutch Mechanism: Delivers smooth, controlled power transmission with minimal vibration—critical for preventing over-torque damage and extending fastener life
  • Twin Hammer Design: Two-hammer impact system provides consistent strike force and improved durability under continuous use
  • 1-Inch Square Drive Anvil: Compatible with standard 1-inch sockets for large industrial fasteners (M38 / 1½-inch range)
  • 4-Position Directional Lever: Forward, reverse, and neutral control allows immediate power direction changes without tool removal
  • Integrated D-Handle & Side Control: Both top D-handle and side grip positions provide operator choice for leverage and control in tight or awkward working positions
  • Low Vibration Operation: Pin clutch design minimizes hand fatigue during extended fastening sessions
  • Compact Design: 437mm length keeps the tool maneuverable in confined spaces typical of industrial assembly lines and equipment maintenance

Business Advantages for Resellers

  • High Margin on Heavy-Duty Segment: 1-inch tools command premium pricing; this model fills a critical gap between common 1/2-inch and specialty 3/4-inch tools
  • Recurring Service & Repair Income: Pin clutch mechanisms are customer-serviceable; filters and anvil maintenance generate steady aftermarket revenue
  • Fleet & Shop Integration: Ideal upsell to automotive shops, heavy equipment dealers, and industrial maintenance facilities already stocking pneumatic tools
  • Bundling Opportunity: Pair with alternative 1-inch models to offer backup tools and redundancy packages to enterprise customers
  • Professional Differentiation: Twin hammer technology appeals to quality-conscious shops seeking reliability over budget options
