Benefits & Use Cases
This versatile mini drill pen excels in environments where detail matters most. Its lightweight, ergonomic design makes it easy to maneuver during extended crafting sessions, while the variable-speed control allows seamless transitions between soft plastics, hard resins, stone beads, leather, shell art, and printed circuit boards. Crafters will appreciate how the low-speed setting (5,000 r/min) enables gentle drilling into fragile materials like acrylic or soft metals, while the high-speed mode (18,000 r/min) efficiently shapes denser items such as wood composites or ceramic accents.
Ideal for hobbyists, jewelry makers, model builders, and DIY enthusiasts, the Uolor mini drill supports a wide array of projects—from customizing keychains and earrings to assembling bracelets, anklets, and board necklaces. The cordless functionality eliminates reliance on fixed outlets, making it perfect for use in workshops, studios, or even outdoor settings when paired with a portable power source.
Please note that while powerful for its size, this tool is optimized for light-duty tasks and not suited for heavy drilling through thick metal, hardwood, or masonry. Always use appropriate speed settings and secure your workpiece properly to maintain accuracy and prevent slippage. With proper care and usage within recommended limits, this mini drill delivers consistent, reliable results across countless small-scale creative endeavors.
Important Notes
When replacing drill bits, always begin by removing the small screw at the tip of the drill using the provided Allen wrench. Loosen this screw fully before inserting or removing the desired bit, then tighten it securely to ensure firm retention during operation. Never force the drill beyond its rated capacity or attempt to operate it while connected to a charger unless necessary for recharging.
For optimal battery life, avoid draining the battery completely before recharging. Store the drill in a dry environment away from dust and moisture to preserve electrical components. Regular cleaning of the chuck area and bit storage compartment will help maintain smooth operation over time.

Nice pen drill to get into tight places!
No.. it is not your 3/8âs or 1/2 inch drill.. it works perfectly for small projects like plastic or wood or balsa wood thin steel.. but it will stop the bit several times if you push hard. Itâs a PEN DRILL! What to expect? But if you go slow it works great and battery charged last a long time! Well worth its price especially for a Hobbyist like me building Airplanes to fully operational submarines in small scale to gas powered RC cars.. etc⦠if you need to drill small holes delicate this is it!

Nice Little Drill
The Uolor 3-Speed Cordless Mini Drill Pen works well on small Projects. It is easy to hold and manipulate.The Battery is easily charged and seems to hold the Charge for quite awhile.I like the Convenience of being able to use this Drill for limited Work without having to break-out my larger Drill and Bits.I have only had this Product for about 2 Months so I cannot address its durability and staying-power.

Very Good for the price
For what I paid, it is useful. However, changing the drill bits is a hassle using the provided Allen wrench. It took awhile to drill accurately with it- slight bit wobble. I bought a more expensive model from another vendor and love that one. But, it was much more expensive and only bought due to the amazon day discount!

will fit tight corners and edges that most drills are too fat for
Its power is limited by its size so this is not construction-grade, but if used properly this can reach tighter spaces than a normal drill. Minimize stress on the motor by scaling up from smallest bit to your desired size, and rest the motor.

If you are looking for a good quality drill that does its job, this is NOT the right choice for you.
If you are looking for a good quality drill that does its job, this is NOT the right choice for you.Five minutes after opening the box, two of the smaller drill heads were already broken. The device is very poor quality, and it doesnât even charge completely (only 3 out of 5 lights turn on even after charging it for hours). Additionally, itâs not strong enough to carve material harder than cardboard or delicate, thin wood. The drill is either defective, or the one I received is used. I am extremely disappointed because I needed it, especially the two drill heads that broke. Not willing to waste my money buying the replacement heads, nor my time to return the drill. Will report the issue to the customer care for a refund.

It’s alright.
I like this for thinner materials. I used it on cloth to afix something on a purse and it did great. I then used it on some resin beads my friend gave me and it was really hard to drill all the way through. I broke one of the smallest bits immediately when it got stuck in a trial bead.Also it overheats quickly and gets the shavings stuck on the drill bits so it can be hard to keep going through without cleaning off the bit or trying to blow out the shavings which is hard when the hole is small and it hasn’t gone fully through yet. I started using water as a lubricant which helped some but the bits rusted after. I think if you have to drill short holes within stronger material or any holes in a thinner material this works but maybe get a stronger one for thicker materials where you have to make a lengthier hole. The battery also runs out quickly so I had to keep recharging it. But it charges quickly. All in all it’s not amazing but good enough for a first drill or if you don’t need one for regular use. Maybe I’ll get better as I use it more and then I’ll be happier with it.

One speed device
Device would not advance to level 2 (10,000 rpm) or level 3 (18,000 rpm). It would just turn off. Turn on – turn off – turn on – turn off. On the plus side, battery was fully charged. Was going to return but just kept fumbling with it and somehow it went to level 2 after level 1. It seems that if I sorta “flick” the on/off button instead of “press” like it says, it goes to next level. Whose idea was that?

Super cool!
Buy spare bits! Just in case it’s very light. Great value for money spent. Great size though I wish it had just a bit more drilling power. It has a great “auto save” feature in its design to save the motor from burning out when it binds while drilling. Overall. Great design.easy to use and functions as it should. I need like 2 more
