Detailed Features Of Metabo HPT NR1890DR
Unique Air Spring Drive System
If you ask what makes the Metabo power tools inimitable from other battery-powered nail guns on the market, the answer is its air spring drive system.
Despite the fact that it is solely powered by batteries, it has compressed air performance. Let’s take a look at how the air spring drive mechanism functions.
Working Procedure Of Air Spring Drive System
Metabo’s Air Spring Drive System consists of a sealed compressed air cylinder and a spring. While running, the spring is rolled and compressed using the power produced by the battery-powered brushless motor and gains momentum. When you turn on the engine, the attached piston moves from downward to upward through the cylinder and compressing air into it. At the moment you pressed the trigger, compressed air is released forcibly, and push the piston downward. The piston then hit the nail head to shoot out from the gun. All these actions happened within a fraction of a second.
Though it has a piston and cylinder like a car engine, it is very distinct from a combustion engine. A combustion engine needs fuel (gasoline or petroleum), whereas the Metabo air spring drive system use spring compression. Therefore, it is economical and safer for our environment too.
From the above-described working procedure, you may seem that it’s a lengthy method, but it’s not. In reality, the brushless motor starts working even before the trigger is pulled. It implies that when you fire the nailer, the fastener is pushed with zero lag at once. It’s always prepared to hit the next nail. The method is fast enough to drive 2/3 nails per second, and its recoil feels like an excellent pneumatic nailer.
Air spring drive system, therefore, will give you the following advantages –
- Zero ramp-up time and faster response time between drives
- No burning noise and no gas fumes
- Consistent performance at low temperatures or high altitudes
- Less maintenance due to no need for regular cleaning of the combustion chamber
Metabo’s spring mechanism is powered by a brushless motor, which we already knew about. As a result, similar to other cordless nailers like the Dewalt, you’ll get frictionless rotation for longer run-time per charge, added longevity, and less maintenance hassle from it.
It will also ensure superior performance and accuracy to sink nails up to 3½ inches of size into any LVL or baseboards even through 5/4 decking boards or 4×4 engineered lumber all day long.
A powerful 18-volt 3.0Ah Lithium-Ion battery is used to supply power to the Metabo HPT NR1890DRS. As a result, you could drive up to 400 nails per single charge with it. Not only will you get enough driving power from it, but it will also give you a compact size for ultimate portability. It is 3/4″ shorter and .6 lbs lighter than other conventional 3.0Ah batteries.
And the battery is compatible to use all of your other 18v slide-type Li-Ion Hitachi or Metabo cordless tools, which is great.
There are also options if you think the above number of actuation isn’t enough to speed up your project and want to drive more nails per charge of battery. Metabo NR1890DRS enables you to increase the battery capacity from 3.0Ah to 6.0Ah. If you set a 6.0Ah battery, you can flush 780 nails per charge. Have a lot of fun! Oh, my goodness!
Please look at the ampere vs. the number of nails per charge graph below for a better understanding.
Low Operating Cost
If you have a Metabo Cordless Framing Nailer, you could save 25% of your operating costs as you no longer need to buy any gas cartridge or air compressor. Moreover, you can drive 25 percent more nails compared to a fuel cell-powered nailer with it. Let’s see the graph below to get more indulgent.
Considerations to draw the above graph:
- Without the cost of nails.
- The numbers of the total cost were relative values when the initial cost of competitor’s gas framing nailer indexed at 100.
- Electricity cost may vary depending on the state you stayed.
The new Hitachi cordless framing nailer came on the market in 2018 and is equipped with a control panel situated right at the base of the handle. You can control particular settings with this panel by pressing buttons.
- To get the device ready for a job, you have to press ‘ON’ switch of the nailer. For a second, you just hold the button, and it comes to life. It is a brilliant feature for the operator’s safety. You can use this button to quickly put the tools in off mode when you are not in action.
- You can check the battery life as there is a LED control to show the battery charge level.
- You can select either sequential or bump fire mode directly using this control panel. Where most other nailers offer a locking switch to change between firing modes, at the worst cases, you have to replace the trigger, Metabo cordless tools make it so easy that you have only press a button to do so. Very cool. Ha!
Depth Of Drive
Adjustment of drive depth is a crucial setting for each nailer. Metabo nail gun addresses it rightly and designs a quick change wheel/dial to align the depth-of-drive, which helps you get precision nailing. Based on your working surface density and variety, now you can set your desired drive depth without using any tools.
We love to mention that Metabo HPT comes with a pivoting rafter hook. Well, you will enjoy it. It’s large enough to hang the tool from a 4x beam, and it’s easy to rotate in or out of place as required.
Non-slip rubberized soft grip reminds us of the mastery in ergonomics of Hitachi power tools. Yes! Because of its ergonomically designed handle, you could enjoy driving nails all day with comfort.
It also comes with a side lock trigger switch located on the handle, which prevents accidental firing when the tool is not in use or you carry it from one place to another.
The tool weight with battery is 10.1 pounds, which is a bit heavier, but in practice, you will find it is a well-balanced cordless nailer for easy maneuverability while working at tight corners.
A dry fire lockout system prevents nailers from firing when fasteners are low for added safety.
Power Saving Mode
Are you going to lunch break without disengaging the battery from your Metabo cordless tools? There’s nothing to worry about! The Metabo HPT NR1890DR will automatically go to sleep mode after 30 minutes of inactivity. This function enables you to save battery power from unnecessarily drain-out and also ensure safety, as no one can accidentally drive nails at that interval.
If you want the tranquility of mind, at the same time, not want to annoy your neighbors, then you come to the right place. Metabo Hitachi cordless nailer concept so that you can achieve the same efficiency as a pneumatic nailer without any combustion or compression noise, drag hoses, or even the smell of gas fumes. Not only is it quiet enough, but it will also provide you with consistent efficiency even at low temperatures and high altitudes.
