The heat of combustion relative to the mass, Qm, was evaluated for 13 deciduous wood species, ranging from low to high density. The maximum and minimum values for Qm ranged, respectively, from 19.01 kJ⋅g-1 (Sd = 7 J⋅g-1) to 21.66 kJ⋅g-1 (Sd = 6

Osnovni dio svake viševretene bušilice jest njezina radna jedinica koja se naziva glava za bušenje. Uporaba viševretenih bušilica omogućuje simultano bušenje rupa u redovima, što čini takve bušilice učinkovitijima od jednovretenih bušilic
