7. WORKING PERFORMANCE PER SINGLE CHARGE
Drilling and fastening performance comparison per charge
Remarks*1: Number of holes or fasteners per charge
The above table shows an example of test data obtained using the battery which is standard for this tool.
As actually measured values listed in the above table may vary depending on sharpness of drill bit, workpiece
hardness (particularly in wood materials), moisture content of wood, charging condition, operator skill, etc. This
data should be used as a comparative guide only.
Mild steel
