Choosing between a 12v or 20v drill used to be simple. Now, not so much.
The dizzying choices between compact 12v models and powerhouse 20v tools can make your head spin.
Do lightweight 12v drills really have enough juice for serious jobs? And are bulky 20v beasts necessary for hanging pictures?
The truth lies somewhere in between. Picking the right drill for you is all about understanding power, portability and features.
This quick guide cuts through the numbers and myths. We’ll highlight where each drill type excels so you can find the ideal match for your needs. Let’s dispel the confusion and zero in on the perfect drill!
How to Choose Between 12V vs 20V Drill
When it comes to drills, one of the most common questions that comes up is whether you should choose a 12v or 20v model. On the surface, the voltage seems to be the key difference between these two drill types, but there are other important factors to consider as well. We’ll break down the key similarities and differences between 12v vs 20v drills to help you decide which is better suited for your needs.
Understanding Voltage and Power Output
The voltage rating on a drill refers to the amount of power it can output. Higher voltage drills can deliver more torque, enabling them to handle tougher jobs involving thicker or denser materials.
12v drills operate off lower voltage batteries and deliver sufficient power for lighter duty tasks like installing screws in wood or drilling small holes.
20v models utilize higher voltage lithium ion battery packs and can generate considerably more turning force for boring large holes or driving screws into tough materials like concrete or steel.
While the voltage plays a big role, it’s not the only factor determining the power and capabilities of these tools. You also have to look at the amp hour (Ah) rating on the batteries, which indicates how long they can run before needing a recharge.
Additionally, advanced motors, gearing and torque settings can vastly expand the functionality of 12v and 20v drills. Many 12v drills now use efficient brushless motors and optimized gearing to produce power approaching that of early 20v models.
So while 20v drills have the edge in power output, there is considerable overlap in capabilities between advanced 12v and basic 20v products. You have to look beyond just the voltage to assess factors like battery life, motor performance and chuck size to determine how well a drill will perform for a given task.
Key Differences Between 12v vs 20v Drills
Now that we’ve covered the basic voltage and power distinctions, let’s take a more detailed look at how these two drill types compare:
The higher voltage of 20v drills translates into considerably more turning force and torque. A typical 12v drill produces around 300 in-lbs of torque, while 20v models generate 400-600 in-lbs. This allows 20v drills to power through denser materials using larger bits.
Higher torque enables 20v drills to drill bigger holes, especially in metal and masonry. Most 12v max out at 3/8” to 1/2″ in steel, while 20v drills can bore holes up to 3/4” or larger. 12v models are suitable for drilling curtain rod holes or driving screws, while 20v drills are better for heavy duty tasks like installing lag bolts.
The lower voltage requirements of 12v drills mean their batteries tend to last significantly longer per charge. A 12v 2Ah battery may operate a drill for up to 8 hours, while a 20v 2Ah battery powered drill will only run for around 2 hours. However, 20v batteries charge faster.
Weight and Size
12v drills weigh 25-30% less than comparable 20v models. Their smaller batteries and motors make them more compact and easier to handle in tight spaces. 20v drills weigh up to 4-5 lbs and can feel bulky during overhead use.
Higher end 20v drills generally offer more power settings, sturdier construction and brighter work lights. However, advanced brushless 12v models now match 20v drills in precision and features. Basic 12v and 20v drills tend to lack power settings, metal gearing and clutch control.
The smaller 12v batteries cost substantially less than 20v lithium ion packs. However, the drill itself may cost more for advanced 12v brushless models. Basic brushed 12v drills are the cheapest options.
As you can see, the voltage rating doesn’t tell the whole performance story. While 20v models have a power advantage, especially for heavy duty tasks, 12v drills are quite capable for common DIY applications and feature impressive battery runtime.
Similarities Between 12V and 20V Drill
Here are 3 key similarities between 12v and 20v drills:
- Both 12v and 20v drills use lithium-ion batteries for long lasting power and rapid recharging.
- Variable speed triggers give users precise control over RPMs for different materials and applications.
- Keyless chucks allow for quick and easy bit changes by hand without needing tools.
In summary, the core technologies of lithium-ion batteries, variable speed triggers, and keyless chucks are common to both 12v and 20v drills. This allows them to provide convenient cordless use, speed control, and versatility regardless of voltage power level.
When to Choose A 12v Drill
Now that we’ve compared the key pros and cons, here are the best uses for a 12-volt drill:
Light Duty DIY Tasks
12v drills work extremely well for common jobs like hanging pictures and curtains, assembling furniture, installing cabinet hardware or screwing plywood subflooring. They have plenty of power for drilling and driving into softwoods and sheet goods.
Precision Drilling and Driving
The smaller size, lower torque and increased run time of 12v drills makes them ideal for detail work. Jobs like drilling small pilot holes or sinking delicate screws benefit from the enhanced control and accuracy of 12v drivers.
Working overhead on a ladder trying to support a 4 lb 20v drill can quickly become fatiguing and unsafe. The lighter 2-3 lb weight of 12v models reduces arm strain for extended overhead installation or construction tasks.
Tight Space Access
The smaller grip and battery pack of 12v drills allows for handier use in confined areas where maneuvering a full size drill is difficult. Jobs like installing shelving in closets and cabinetry are easier with compact 12v drivers.
Portable and Multi-Tool Use
Contractors, electricians and maintenance workers who need to carry tools from place to place prefer the lighter 12v drills for daylong portable use. The variety of 12v powered rotary and oscillating tools also enables efficient one-battery multi-tool use.
Budget Conscious Buyers
While prices vary widely, 12v brushed drill and battery kits can often be purchased for under $50. This makes them appealing for cost conscious DIYers who only tackle light duty drilling/driving tasks from time to time.
For most homeowners, 12v drill/drivers offer the ideal balance of power, portability and value for general around-the-house use.
Best Uses for A 20v Drill
20v cordless drills really shine in these applications:
Heavy Duty Drilling
Lag bolts, spade bits and hole saws require tremendous torque, especially in dense materials. 20v power easily bores 3/4” plus holes through solid wood, steel and masonry. 12v models bog down and lack the sustained torque for big bits.
Driving Long Screws
Deck construction, framing and other jobs requiring driving long screws benefit from the brute force of a 20v impact driver. Their extra power drives fasteners cleanly without stripping or breaking screw heads.
Extended High Power Use
Big projects like building a deck involve drilling and driving all day long. 20v lithium ion packs sustain high power output for several hours without fading or dying mid-job like lower voltage batteries can.
Frequent Recharge Cycling
Contractors and tradesmen work drill/drivers hard every day. 20v batteries hold up better to the frequent discharge-recharge cycles demanded by heavy professional use. Heat and wear take a greater toll on 12v packs.
Outdoor Job Site Use
The generator-like power of 20v tools makes them favored by builders and contractors for outdoor job site use. Rain, dirt and rough conditions are no match for the sturdy 20v drill design.
Hammer drills, right angle drivers, hole saws and other accessories call for maximum drill power. Specialty carpentry, plumbing and electrical bits work best with higher torque 20v models.
Investing in a 20v drill means you can add higher draw tools like circular saws, grinders and grease guns while using the same battery system. 20v tools prevent unexpected power limitations as your capabilities expand.
While their upfront cost exceeds 12v drills, 20v models offer long term value for professional contractors or avid DIYers needing serious drilling and driving power.
