Makita XFD131: the precision speed controller for metal work

Makita XFD131: the precision speed controller for metal work

The Makita XFD131's self-tightening chuck held round-shank cobalt bits without any detectable wobble throughout our metal drilling test, which directly contributed to the rounder, cleaner hole entry faces we observed in our caliper measurements. The variable trigger provided the smoothest low-speed control of any drill in our test: we maintained 350 RPM for our steel drilling without hunting or surging, which is critical for clean metal holes.

Milwaukee 2801-20 M18 FUEL: the M18 precision drill

The Milwaukee 2801-20 FUEL drill matched the Makita on most metal drilling metrics and is the natural choice for M18 platform users. Its 0-2,000 RPM range and brushless motor delivered consistent speed in our steel drilling test. Hole quality was comparable to the Makita in mild steel; in stainless, the Makita's self-tightening chuck provided a marginal advantage in hole roundness due to better bit stability. For standard mild steel and aluminum work, the Milwaukee is equally capable.

Buying considerations

Variable speed trigger

Low-speed control (under 500 RPM) is essential for drilling steel. A trigger with smooth low-speed response is more important for metal drilling than maximum RPM.

Chuck stability

Self-tightening chucks and all-metal chucks hold round-shank drill bits more rigidly than plastic keyless chucks, which reduces bit wobble and improves hole roundness.

Brushless motor

Consistent speed under cutting load is the primary advantage. Brushless motors maintain their set RPM better than brushed motors when drill pressure increases in tough materials.

Two-speed gearing

Low gear (first speed) provides maximum torque at slow RPM, which is the correct setting for metal drilling. High gear is appropriate for wood and light assembly work.

Torque setting

For metal drilling, set the clutch to its drill mode (no slip) rather than a torque clutch position. You want direct drive without clutch slippage during hole completion.

Questions answered

What RPM should I use for drilling steel?

For drilling mild steel with standard twist bits, use 300 to 600 RPM for 1/4-inch bits and 100 to 300 RPM for 1/2-inch bits. Slower speeds with firm steady pressure produce better holes and extend bit life in metal.

What drill bits should I use for metal?

Cobalt HSS (M35 or M42) bits are best for hardened steel and stainless. Standard HSS bits handle mild steel and aluminum. Black oxide bits are adequate for light aluminum work. Avoid standard wood bits in metal -- they will break or walk on the surface.

Do I need cutting oil when drilling metal with a cordless drill?

Cutting oil extends drill bit life significantly when drilling steel or stainless. Apply a drop of cutting oil to the drill point before each hole. For aluminum, cutting oil is optional but beneficial. It reduces heat and produces cleaner chip evacuation.

Can a cordless drill drill stainless steel?

Yes, with cobalt bits and correct technique (low speed, firm pressure, cutting oil). Stainless work-hardens if you drill too slowly or stop mid-hole. Maintain steady pressure and complete the hole in one pass.
