Comparison of Nails per Charge*
The NT1865DBSL cordless finish nailer, for example, drives up to 2,650 nails per charge with a 6.0Ah battery, up to 2,450 nails with a 5.0Ah battery and up to 1,500 nails with a 3.0Ah battery.
* The number of nails per charge may vary depending on operating conditions, hardness of work pieces, etc.
  • Lower running costs
No cost of gas cartridges means that the more the tool is used, the more cost-effective it will be.

Comparison of Total Cost*1
When you drive more than 4,900 nails, the total running cost will be lower than a gas nailer.
*1: Without the cost of nails.
*2: The numbers of total cost are relative values when the initial cost of competitor's gas brad nailer is indexed at 100.
*3: Electricity cost may vary depending on the area.
  • Ease of use with great comfort
Air Spring Drive System A unique air spring drive system that uses the compressed air sealed in the main unit brings various advantages of pneumatic technologies.
· Drives 3 nails per sec. with zero ramp-up time and quicker response time between drives.
· Low-recoil, yet powerful enough to set nails flush consistently.
· No combustion noise and no gas fumes.
· Consistent performance even at low temperatures or high altitudes. (The operating environment for these products is between 0℃ and 40℃.)
