How to clean and maintain a drill
It’s easy to take tools for granted, and just expect them to work whenever we need them. However, our tools require a little bit of TLC every now and again. Your drill is no exception. A quick clean and check can extend their life and make yours more stress-free! Whether your drill is plug-in or cordless, there are component parts that you should look at. Here’s a step-by-step guide on how to clean a drill, with help from WD-40®!
Things you will need
Microfibre cloth
WD-40® Multi Use Product
WD‑40 Specialist® White Lithium Grease
Compressed air (optional)
Drill bit sharpener (optional)
Step 1
Store Correctly to Prevent Rust
Firstly, make sure you store your drill correctly. If it came in a case, keep it in a case! A case will keep the drill away from circulating dust particles and moisture.
If you use your drill in wet conditions, be sure to dry it completely before you put it away. Moisture can lead to rust formation. This, in turn, can jam the chuck and other moving parts including the motor itself. If you do spot any rust, then WD-40® Multi-Use Product can be used. Simply spray a little on a microfibre cloth and gently work it into the drill’s metal surfaces. This will create a water displacing layer that will help to protect your drill from rust. Always test on an inconspicuous spot first to determine compatibility with the drill’s surfaces.
Step 2
Wipe down the drill
To clean and maintain your drill, start by giving it a quick wipe down. Just use a microfibre cloth and give the drill a gentle rub to remove any dust and grime. It is important to wipe down the drill after every use as chippings from whatever you have drilled can attach themselves to the outer casing.
Step 3
Clean the ventilation slots
Occasionally, your drill will require more than just a rub down. Most drills have ventilation slots that will clog up over time. If the ventilation slots are not cleaned regularly, then damage can be caused to the internal machinery.
To clean these ventilation slots, don’t use a brush as this could push any dirt further into the slot. The best way to clean the ventilation slots of your drill is to gently blow into them or use a shot of compressed air. This helps remove any debris stuck in the slots.
Step 4
Lubricate well
Drills require periodic lubrication to prevent chafing, corrosion, and overheating. If your drill bit isn’t spinning freely, check for any small fragments that might be stuck at the base near the chuck. If it’s clean, there’s a chance that the chuck is jammed. This can be solved using a lubricant such as WD-40 Specialist White Lithium Grease. Simply spray some of the product onto the affected area and massage it in, no need to wipe it away. WD-40® will get your drill moving smoothly again!
Step 5
Keep drill bits sharp
The final step, if you want to clean and maintain your drill well, is to inspect the bit. Either replace your drill bits regularly or sharpen them. You can buy drill bit sharpeners at DIY retailers or online.
