Drilled and split a little bigger amount. Took days. Darda c12 and a Chinese 12 ton. 5 or 6 times the Chinese unit jamed and not retract. Had to use Darda to rescue Chinese out of hard granite. I used feather and wedges for some situations. Saw your video a year ago and it inspired me. After being stuck with only 1 splitter rented I rented a 2nd unit which was Darda. I would always use 2 splitters now. At 7:45 I heard the only word that translated directly to English. When drill stuck. Fu ck Lol Great video Thank You Canada.
I notice that you are using taper rods and knock on drill heads, do you have problems with the drill heads coming off when you are using such a large diameter bit and a light drill like the RH571? Jag märker att du använder koniska stänger och knackar på borrhuvuden, har du problem med att borrhuvudena lossnar när du använder en så stor diameter borr och en lätt borr som RH571?
