Selection Guide: Maintenance Impactools™ for Vehicle Repair

Question

Which air operated Maintenance Duty Impactool™ should I choose for my application?

Environment

Impacts used for general maintenance, tire changing and bolt-changing operations in Automotive Service Centers, Fleet Maintenance Centers, and for MRO (Maintenance, Repair & Operations) applications.

Answer

Impactools are typically selected on the basis of Drive Size, Bolt Size, and/or Required Torque. 

Key Selection Questions to be considered:

1. What is the Size of the Bolt to be fastened?
2. How much Torque is required in Ft-Lbs/Nm for the application?
3. What Drive Size is needed for the Impactool and Sockets?
4. What is the Frequency of Use for the Impactool (e.g. continous, intermittent, or occasional)?
5. 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:

1. Rule #1: Square Drive Size = Maximum Bolt Size
2. Rule #2: Impacting Time = 3-5 Seconds (max)
3. Tip: Exceeding the 3-5 second Rule may cause excessive impact mechanism wear and heat
4. Rule #3: If actual Impacting Time is => 10 Seconds, select a larger/higher torque tool
5. Rule #4: Choose an Impact for the "worst-case" scenario for which the tool will be routinely used
6. 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.
