Which air operated Industrial Duty Impactool™ should I choose for my application?
Impacts used for general maintenance, non-critical torque assembly, and bolt-changing operations in Production, Power Generation, Construction and other MRO (Maintenance, Repair, & Operations) applications.
Impactools are typically selected on the basis of Drive Size, Bolt Size, and/or Required Torque.
Key Selection Questions to be considered:
- What is the Size of the Bolt to be fastened?
- How much Torque is required in Ft-Lbs/Nm for the application?
- What Drive Size is needed for the Impactool and Sockets?
- What is the Frequency of Use for the Impactool (e.g. continous, intermittent, or occasional)?
- What are the Ergonomic needs of the tool operator for the application (e.g. tool weight, handle type, easy and comfortable accessibility to the work piece)?
General Selection Guidelines and Tips:
- Rule #1: Square Drive Size = Maximum Bolt Size
- Rule #2: Impacting Time = 3-5 Seconds (max)
- Tip: Exceeding the 3-5 second Rule may cause excessive impact mechanism wear and heat
- Rule #3: If actual Impacting Time is => 10 Seconds, select a larger/higher torque tool
- Rule #4: Choose an Impact for the "worst-case" scenario for which the tool will be routinely used
- Tip: Impactools can use a lot of air, especially as they increase in tool/drive size; a proper air supply (air pressure and scfm air flow) will help provide maximum performance.
