Drill Torque Control
Ever wonder what those numbers are for on the tip of your drill? The ones that you can spin but no one actually talks about what they do? If you’re new to the drill world or if you’ve just bought a drill to install some curtains in your house, chances are you have no idea what these numbers are for.
Before We Begin
It’s worth noting that not all drills are the same so if you check your drill and find different numbers and settings don’t get concerned. This is normal and you can find your drill specifications on the manufacturer’s website.
To understand the importance of drill torque control we must first get an understanding of why it matters. If you have ever screwed into a piece of wood with a flat head wood screw, you may have seen that the top of the head drops below the surface of the wood. Flat head wood screws have a head designed to sit flush with the surface of the wood. If you over-drill chipping may occur around the edge of the hole over time. Over-torquing can damage the surface material, under-torquing will not advance the screw.
A drill clutch is a built-in device used to control the amount of drill torque before a breaking point. This is known as a slip clutch. You may know this as the sound of clicking that occurs when you are trying to screw something in, but it won’t turn. A clutch is designed to slip once the appropriate level of torque is achieved so that the screw being installed will not hurt the material it is being installed into.
Most drills have numbers with preset torque points. Turning the numbered dial from side to side. Our drill starts at the number 1 which is the least amount of torque meaning slippage will happen under very little torque. It ends at 15 which is the highest output the drill can handle. There is also a drill setting that has no slippage and is only supposed to be used with a drill bit. You can adjust the torque by turning to a new number once your drill clutch begins to slip.
If you are unsure about the proper torque to use start with a lower number and begin installing your screw. If your clutch starts to slip, simply move the settings
up to a higher number and continue. Your goal is to get the clutch to slip right as the head rests in its intended position so you do not run the risk of hurting the material you are installing into.
You now know everything you’ll need to about a drill clutch and torque control to get started with all your DIY or professional projects!
