Forstreich Drill Cone

The drill cone is available in two sizes:  SW 16 and SW 22, 

This means that if you already have the felling wedge, you can easily change your tools without having to change the impact nut.:  the TR24-AQ  wedge and drill cone is the same as for the with SW 16 drill cone, and the  the TR30-AQ  uses the same as the  SW22 drill cone.

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 smaller/weaker wood
3.) As a felling aid for climbers to push over tree tops
