ImpactaTaps & MAX ImpactaTaps - Data Sheet
BEST PRACTICE ADVICE
GUIDELINE PARAMETERS ONLY - Actual parameters may vary depending on operating conditions
1. ImpactaTaps are recommended for through hole applications only
2. Spiral Flute ImpactaTaps are primarily recommended for blind hole applications using a clutched adapter to prevent the Tap
from breaking when it reaches the bottom of the hole (See pages 22 & 23)
3. Pilot drill the exact tapping size hole for best results
4. Select the correct torque for Impact tools using the table opposite. If exact match is not available select the closest torque
setting above the recommendation
5. Select the correct RPM when using rotary drive tools using the table opposite.
6. Apply 昀椀rm, steady feed pressure throughout the cut
7. Ensure the Tap is inserted squarely to the hole - poorly aligned or o昀昀-centre taps will greatly increase the risk of breakage
8. Regularly apply quality cooling lubricant, especially when drilling thick or hardened materials
9. Hardened or heat-a昀昀ected materials may require higher torque, reduced RPM and feed rates and extra coolant
10. Flame cut/punched/pro昀椀led holes will require more torque to tap than drilled holes due to heat build up.
Caution: Sometimes 昀氀ame cut holes do not have parallel sides meaning risk of tap breakage
11. Tap the hole in one pass where possible, applying adequate lubrication before you start.
12. If the tap is over-run from the hole once it is tapped, to remove the risk of cross-threading/damage to the tap, remove the tap
from the adapter and locate it in the thread by hand, before reversing
13. When using cordless tools, torque may drop once the battery charge becomes low. Keep batteries well charged. Low battery
charge can lead to lower torque which can break or damage taps as point 4
14. When re-threading an existing thread, use caution to avoid cross-threading which can lead to tap breakage or thread
damage. It is advisable to insert/start the tap into the thread by hand before driving it through at the correct torque
15. Follow guidelines to set correct Impact Torque/RPM. Insu昀케cient torque/incorrect RPM can lead to poor life & tool breakage
N.B. Impact Torque recommendations are the minimum required and for most applications additional torque is a bene昀椀t
