GUIDELINE PARAMETERS ONLY - Actual parameters may vary depending on operating conditions
1. Follow guidelines to set correct Impact Torque/RPM. Insu昀케cient torque/incorrect RPM can lead to poor life & tool breakage
2. Apply 昀椀rm, steady feed pressure throughout the cut
3. Avoid lateral movement or tilting which can cause damage to the tool
4. Ensure regular application of quality cooling lubricant, especially when drilling thick or hardened materials
5. Hardened or heat-a昀昀ected materials may require higher torque, reduced RPM and feed rates and extra coolant
6. VersaDrive® Drill Bits up to 3/8" diameter can be driven by an Impact Wrench
QUICK GUIDE
MORE INFO
- Optimum life and performance when used with Rotary Pistol Drills
- Up to 3/8" can be used on Impact Wrench & Impact Drivers for fast cutting performance
- Suitable for harder materials such as stainless steel when used at reduced RPM
- Use appropriate lubrication and correct RPM to achieve long tool life
