Best Cordless Drill for Metal
Cordless drills have transformed the power tool industry by providing unprecedented mobility without the encumbrance of a power cord. Particularly in metalworking, where precision and power are paramount, the right cordless drill can make all the difference.
In this article we’ll talk about some considerations that you should make when choosing a cordless drill for metal drilling, ensuring you get the best performance for your specific needs.
Key Factors to Consider When Buying a Cordless Drill for Metal
Power (Voltage, Torque)
The ability of a cordless drill to efficiently penetrate metal is largely determined by two factors: voltage and torque. Voltage correlates with the overall power capacity of the drill; higher voltages mean more power. For light metalwork, a drill of 12 volts may suffice, but heavy duty tasks often require 18 to 20 volts.
Torque, measured in Newton meters (Nm), indicates the drill’s turning strength. High torque is crucial for drilling through tough metals. Light tasks generally need less than 30 Nm, whereas demanding operations might need over 50 Nm.
Selecting a drill that offers adjustable torque settings provides versatility across various metal types and thicknesses.
| Usage Type | Torque Requirement |
|---|---|
| Light Duty | Less than 30 Nm |
| Medium Duty | 30-50 Nm |
| Heavy Duty | Over 50 Nm |
Chuck Size and Drill Bits
The chuck holds the drill bit in place and its size determines the diameter of the bit that can be used. Standard sizes are 1/4 inch, 3/8 inch and 1/2 inch, with the latter being ideal for heavy duty metal drilling due to its compatibility with larger bits.
When working with metal, using the right drill bit is crucial; high speed steel (HSS) bits are common, but cobalt bits are preferred for tougher metals due to their superior heat resistance and longevity.
Speed and Gear Options
Variable speed control is critical when drilling metals. Different metals and bit sizes require different speeds to cut efficiently and avoid damaging the material or the tool.
Drills with multiple speed settings offer the flexibility to optimize performance, typically ranging from slow speeds for large bits through hard metals to high speeds for small bits in soft metals.
Hammer Drill Function (Optional)
While not essential for drilling into metal, the hammer drill function allows the drill to bore into masonry and concrete, useful for tasks that involve setting anchors into these materials. This dual-functionality can be a valuable addition for those who work with various materials.
Ergonomics and Weight
Long periods of drilling demand a drill that is ergonomically designed to reduce fatigue. Lightweight models minimize strain on the wrists and arms, particularly important when working in awkward positions or tight spaces.
Features such as padded grips and balanced designs enhance control and comfort.
