Which Drill Should You Use for Drilling Metal?
Choose a handheld drill or drill press for metal by speed range, steel capacity, chuck fit and workholding—not maximum torque alone.
For occasional holes in ordinary steel or aluminum, start with a variable-speed drill/driver whose manual covers the material and hole diameter. If buying a general-purpose handheld tool, a two-speed transmission and 1/2-inch chuck are useful priorities. Choose cordless for mobility, corded when charging interruptions would be inconvenient, and a drill press when the work fits on its table and controlled alignment matters.
You do not need hammer action for metal. A hammer drill can serve, but select rotation-only mode: Makita’s HP2050 manual explicitly specifies this for metal drilling. Do not pay extra for hammer mode solely for this job.
Choose the machine around the work
| Your work | Practical starting choice | What to check before buying |
|---|---|---|
| Occasional holes in brackets, sheet or installed metalwork | Cordless drill/driver | Rated capacity, low gear, bit-shank fit and working clearance |
| Repeated handheld drilling near an outlet | Corded variable-speed drill | Suitable speed range, auxiliary handle and rated metal capacity |
| Repeated holes in movable parts, or holes requiring controlled angle and depth | Drill press | Minimum spindle speed, metal capacity, reach, travel and room for a secured vise or fixture |
These are selection judgments, not a tested product ranking. An existing drill may already cover the job; check its manual before replacing it.
Corded does not automatically mean suitable for every metal hole. For example, DeWalt lists its DWD210G corded drill at 0–1,250 RPM with a locking side handle. Those are useful features to compare, but neither the cord nor its 10-amp rating establishes your required drilling capacity.
The specifications that actually decide the purchase
1. Speed range and low gear
Look beyond maximum RPM. At the same recommended cutting speed, a larger bit needs fewer revolutions per minute. The alloy, bit and setup determine the appropriate cutting speed; there is no single “metal RPM.” JET’s drill-press manual explains this relationship and the variables affecting it.
As an illustration—not a universal speed prescription—using 30 surface feet per minute in JET’s formula, RPM = 3.8 × SFM ÷ bit diameter in inches, gives approximately 230 RPM for a 1/2-inch bit and 910 RPM for a 1/8-inch bit. This is why both low-speed control and enough upper-range speed matter.
A variable-speed trigger and a mechanical low gear do different jobs. On the Makita XFD14, for example, the manual identifies low gear as low speed/high torque for heavy loading, and high gear as high speed/low torque for light loading. Its listed no-load ranges are 0–550 and 0–2,100 RPM. That is a useful specification pattern to look for, not proof of measured performance under load.
2. Metal capacity—not chuck size alone
Chuck size concerns the shank the jaws can hold. Drilling capacity concerns the tool’s stated application limit. Check both, including any separate limits for twist bits and hole saws.
The distinction can be gear-specific: Makita lists the HP2050 with a 1/2-inch chuck, but steel capacities of 1/2 inch in low gear and 5/16 inch in high gear. A bit fitting the chuck does not authorize using it in every gear or material. A reduced-shank bit likewise solves fit, not machine capacity.
For bit selection, use the separate metal drill-bit guide; the machine still needs to suit the selected cutter.
3. Control and workholding
For a handheld drill supplied with an auxiliary handle, plan to use it. Makita’s XFD14 manual requires the side grip and warns of strong reaction forces at breakthrough. It also requires securing workpieces in a vise or similar hold-down device. Handle and clamping requirements are part of tool selection, not optional extras.
For a drill press, check that the hole location is within the spindle-to-column reach and that the bit, workpiece and vise fit beneath the spindle. Confirm sufficient spindle travel for the required depth and a speed range matching the cutter. Secure the workholding to the table; do not hold metal by hand. JET’s manual requires clamps or a vise secured to the drill-press table.
If your current handheld drill meets the capacity, speed and fit requirements but you cannot hold it square or secure the part reliably, prioritize a better setup—or a suitable drill press—rather than shopping for a higher maximum-torque number.
