12V or 20V cordless drill — which do I need?

A 12V drill is perfect for light-duty tasks like hanging pictures, assembling furniture, and driving small screws. For general construction, deck screws, drilling in hardwood, and versatility, a 20V drill is the better all-around choice.

What is a brushless motor and is it worth it?

A brushless motor uses electronic commutation instead of carbon brushes, resulting in 25-50% longer runtime, more power, less heat, and longer motor life. It costs more but pays for itself in performance and durability.

How do I use the clutch settings?

The clutch prevents over-driving screws. Lower numbers (1-5) disengage at light torque for small screws in softwood. Higher numbers (15-20) allow more torque for large screws in hardwood. The drill icon bypasses the clutch for drilling holes.

Drills & Drivers

$40-$80 for 12V kits, $80-$150 for basic 18V/20V kits, $150-$250 for brushless kits with two batteries, $200-$350 for premium brushless kits.

The cordless drill is the single most essential power tool for DIYers and professionals alike. Combining a motor, adjustable clutch, variable speed trigger, and rechargeable battery, it drills holes and drives screws in wood, metal, plastic, and light masonry. Modern lithium-ion batteries deliver impressive power and run times, making corded drills nearly obsolete for most applications.

Modern lithium-ion batteries deliver impressive power and run times, making corded drills nearly obsolete for most applications.
Cordless drills are used for drilling holes in wood, metal, and plastic, driving and removing screws, assembling furniture and cabinets, installing hardware and hinges, boring holes with spade bits and hole saws, mixing paint and thin-set (low-speed models), and general construction and maintenance tasks.
Voltage (12V, 18V/20V), brushless motor (longer life, more power, less heat), chuck size (3/8 or 1/2 inch), clutch settings (15-25 positions), 2-speed gearbox (low for driving, high for drilling), max torque (in-lbs), LED work light, battery type and capacity (Ah), belt clip, magnetic bit holder, and compact size for tight spaces.

What It's Used For

Cordless drills are used for drilling holes in wood, metal, and plastic, driving and removing screws, assembling furniture and cabinets, installing hardware and hinges, boring holes with spade bits and hole saws, mixing paint and thin-set (low-speed models), and general construction and maintenance tasks.

Types & Variations

12V Compact (lightweight, for light-duty work and tight spaces), 18V/20V Standard (most popular all-around choice), 20V Brushless (longer runtime, more power), Compact Sub-Compact (ultra-light for overhead work), and Hammer-Drill Combo (adds hammer function for masonry). Note: DeWalt 20V MAX and Milwaukee M18 are 18V nominal.

How to Use

1) Insert the correct bit into the chuck and tighten by hand or with the ratcheting mechanism. 2) Select the speed setting — low gear for driving screws, high gear for drilling. 3) Set the clutch to the appropriate level — lower numbers for small screws, higher for large screws, drill symbol for drilling. 4) Mark your drilling point and use a center punch for metal. 5) Start at low speed to establish the hole, then increase speed. 6) For driving screws, let the clutch disengage at the correct torque to avoid stripping.

⚠️ Safety Tips

Wear safety glasses when drilling, especially in metal. Secure small workpieces with clamps — never hold them by hand while drilling. Be cautious of the bit catching and spinning the workpiece. Use the auxiliary handle for large bits. Check for hidden wires and pipes before drilling into walls. Remove the battery when changing bits. Start slowly on slippery surfaces like tile.

Maintenance

Charge batteries before they fully deplete to extend life. Store batteries in a cool, dry place. Clean the chuck jaws and keep them free of debris. Blow dust from motor vents with compressed air. Inspect the chuck for wobble and replace if worn. Apply a drop of oil to the chuck mechanism periodically. Keep the tool clean and dry.

Price Range & Recommendations

Price Range: $40-$80 for 12V kits, $80-$150 for basic 18V/20V kits, $150-$250 for brushless kits with two batteries, $200-$350 for premium brushless kits.

Beginners should get the Ryobi ONE+ P215K ($60 range) or DeWalt DCD771C2 ($80 range) — both are reliable and affordable. For better long-term value, invest in a brushless model like the DeWalt DCD791D2 or Milwaukee M18 2801. Pros need the Milwaukee M18 FUEL 2903 or DeWalt DCD800 for maximum torque, compact size, and compatibility with their existing battery platform.
