The drill cone is available in width across flats 16 and 22.
This means that you can easily change the impact wrench between the TR24-AQ and drill cone with SW 16 without having to change the nut.
The same applies to the TR30-AQ with the matching drill cone with SW22.
The drill cone is a device that fulfills 3 functions:
1.) as a re-setting wedge for the TR30-AQ or the TR24-AQ.
2.) felling of weak wood with the impact wrench
3.) In combination with a wrench ratchet or a light impact wrench as a felling aid for climbers to push over tree tops
