Tool Talk: Inline Cordless Screwdrivers
Mike and Brant from Sumake North America: Tool Talk. Today we’re going to cover our new inline cordless screwdrivers. These packages come with the driver, two batteries, a torque cover, a belt hook or hanging hook and a couple bits.
The batteries are 10.8 Volts, 3 amps. They should last approximately 8 hours. We sell the package with two batteries just so you always have one charging – especially if you’re doing two shifts. The batteries are very easily inserted into the battery charger as well as easy to remove from the screwdriver.
This tool has a brushless motor, an auto-stop clutch and a torque dial at the tip of the driver to allow you to change the torque. As you twist this dial either clockwise or counterclockwise you’re going to be either increasing or decreasing the torque against the scale that’s on the tip of the driver. Clockwise is to increase, counterclockwise is to decrease. The tool also features audible and visual torque status indicators which can be turned off on request, but will indicate whether the clutch was tripped properly or not to the operator.
So let’s run this down. You’ll notice it’s very smooth, quiet and it’s also very accurate. This clutch is accurate to +/- 3%. Now if I turn the tool around, you’ll notice it has not been beeping as it just did there, you’ll see the top light here will light up green when there’s a successful fasten.
Error Beep Review
For demonstration purposes I’m going to stop the screw before it seats to give a no good indication. You’ll notice at the bottom here there’s going to be a red light that comes on in one long deep will indicate that the screw is not applied properly.
When to Use Inline Cordless Tools and Angle Adapters
What we’ve noticed is that most of our customers that are purchasing these to work at work stations where there’s not already electrical ran. So they don’t have to run the Electric, they can just have a cordless tool work there. We’ve also seen a lot of people purchasing these that are actually having assembly where they have to walk around, so they’re not carrying a cord with them as they walk around. We have some customers who are actually looking for a small angle cordless tool, so we also developed an angle adapter. You can remove this part and put on the angle adapter to turn it into an angle screwdriver as well.
Torque Cover Overview
Let’s talk about the torque cover. To put the torque cover on, the first thing you do is remove this collar. Now we are ready for the torque cover. A good question is why do we need the torque cover? As you can see it’s easy to move this torque setting knob which would change your end result of what your torque is. So what’s suggested is once you set the screwdriver up for the torque for your application, you use the torque cover to ensure that it doesn’t get changed during the operation of inserting the screw. So now, if your end user grabbed on here they are not going to be twisting the torque knob and changing the torque. So we highly suggest that you use the torque cover that comes with the tool.
Inserting a Bit
These assembly drivers come with your standard quarter inch hex female bit receivers. When you’re changing the bit either putting one in or taking it out, you should always have the driver on neutral so there’s no chance the driver starting up on you. To put the bit in, simply line it with the bit receiver, stick it in part of the way and grab the bit receiver and pull away from the driver. At that point, you can stick it in the rest of the way and ensure that it’s locked in place. To take it out, just reserve those steps, pull the bit receiver away from the tool, pull the bit out and then you can remove it and switch to a different bit.
Battery Charger Overview
Let’s take a look at the battery charger for this cordless tool. The battery fits in here quite easily as I mentioned earlier. Once you put it in, there’s indicator lights at the top to tell you what’s going on. The red blinking light means that this battery is being charged. Orange means that it’s less than 80% charged. Once it becomes fully charged, the green light will come on and these two lights will go off and it will indicate that the battery charger has charged. Relatively easy to use and a battery that’s been run down to about 20% life cycle left will take just under an hour to charge. That’s one of the reasons we deliver two batteries with this package.
Inline Cordless Tool Maintenance
So it’s recommended that you send in these tools to be recalibrated and certified every year. If you’re using them three shifts a day, it’s recommended between six and in 12 months but if you’re using the standard one to two shifts a day each year should get you by just fine.
