PERFORMANCE PARAMETERS BASED ON POWER OF DRILLING EQUIPMENT FOR DIFFERENT DRILL BIT DIAMETERS

Condition of interdependence 1:

The smaller the diameter of the drill, the faster the drilling speed and shorter lifetime

Condition of interdependence 2:

The more power the machine has, the faster the drilling speed and shorter lifetime of the drill.

Performance parameters are given for following conditions:

• Reinforced Concrete drill bit;

• vertical drilling of medium abrasive concrete M400;

• agglomerate: granite chips;

• reinforcement: 22 mm in 4 rows on 300 mm length;

• revolution speed and water feed according to standard;

• at an air temperature of +25 °C;

• working with an the operational drilling machine. The data is for information only. Under other operating conditions the performance parameters may vary.
