The Forstreich SK50 spiral drill bit – handy, compact and powerful
Thanks to the self-tapping spiral of the SK50 spiral cone, which is KWF-Profi certified, there is no need to widen the saw cut. This makes it ideally suited for the safe felling of weaker timber and small-diameter trunks. Weighing just 1.7 kg and with a maximum stroke height of 55 mm, it exerts a remarkable 5 tonnes of pressure on the tree.
Properties and uses
Two hardened hex sockets with a wrench size of 16 and 22, each featuring a bore hole, are available for connection to the impact wrench. This means that the SK50 spiral wedge can also be conveniently combined with our other felling wedges and used, for example, for re-tightening.
The symmetrical shape of the spiral reliably prevents the SK50 from working its way out of the wood.
A generously sized, lubricatable roller bearing ensures efficient power transmission and guarantees a long service life.
