Radial Arm Drill Press: The Right Machine for Large Panels and Angled Holes
You have a tabletop that is 36 inches wide, and you need a row of perfectly aligned holes down the center. A standard drill press can drill the middle, but the throat depth limits how far you can reach without repositioning the work. Every time you move the piece, you risk misalignment. A radial arm drill press solves this by moving the head along a horizontal arm instead of moving the workpiece. The swing is variable, and the head tilts for angled and horizontal drilling.
A radial arm drill press is a floor or benchtop machine with a head that slides along a horizontal arm extending from the column. The arm can be 34 inches long or more, which lets you drill holes far from the column without moving the base. Most radial arm presses also tilt the head 90 degrees left or right, turning the spindle horizontal for edge drilling and mortising. The table tilts too, adding even more flexibility for angled joinery and hardware.
If you build furniture, cabinets, or work with large sheet goods, a radial arm drill press gives you reach and angles that a standard press cannot match. The trade-off is size, weight, and price. These machines are larger and heavier than standard presses, and the long arm creates leverage that demands a sturdy bench or a bolted floor installation.
Three Radial Arm Drill Presses That Earn Their Floor Space
The Palmgren Radial Arm 5-Speed Floor Step Pulley Drill Press is a 1/2-horsepower floor model with a radial arm that extends from 9 to 33 inches. The head tilts, the table tilts 45 degrees left and right, and the five speeds range from 600 to 2,592 RPM. The spindle travel is 3-5/32 inches, and the table is cast iron with a rack-and-pinion height adjustment. The base is a wide cast iron pedestal, and the machine weighs about 190 pounds.
What keeps it from being perfect is the price and weight. This is a serious machine for a serious shop. The variable swing is excellent, but the arm is not as rigid as a fixed head at full extension. If you push a large bit at the outer reach of the arm, you may get slight deflection. For large panels and furniture work, the Palmgren is a reliable choice. Skip it if your shop is small or your work is small enough for a standard press.

The Grizzly G7945 34-Inch Benchtop Radial Drill Press is a 1/2-horsepower benchtop model with a 34-inch swing. The head tilts 90 degrees left and 45 degrees right, and the table tilts 90 degrees left and right. The five speeds range from 550 to 3,000 RPM, and the spindle travel is 3-1/4 inches. The base is cast iron, and the machine weighs about 110 pounds. It is designed to sit on a sturdy workbench rather than the floor.
The honest flaw is the benchtop format. A 34-inch radial arm on a benchtop creates a lot of leverage. If your bench is not deep, heavy, and bolted down, the machine will flex or tip when you drill at the outer reach of the arm. The table is also smaller than a floor model, which limits the size of the workpiece you can support. For a shop with a solid, deep bench and no floor space, the G7945 is a good compromise. For a production floor, buy a floor model.

The Shop Fox W1669 34-Inch Benchtop Radial Drill Press is a 1/2-horsepower benchtop model with a 34-inch swing. The head tilts 45 degrees left and 90 degrees right, and the table tilts 90 degrees left and right. The five speeds range from 550 to 3,000 RPM, and the spindle travel is 3-1/4 inches. The base is cast iron, and the machine weighs about 110 pounds. It is very similar to the Grizzly G7945 in specifications and capacity.
The flaw is the same as the G7945: it needs a heavy, deep bench to be stable at full extension. The table is small for large panels, and the head may flex slightly at the outer reaches of the arm. The Shop Fox is a close alternative to the Grizzly with slightly different tilt geometry. For most home shops, the choice between the two comes down to availability and price. Buy the one you can find. For a production shop, upgrade to a floor model like the Palmgren.

Who Should Skip a Radial Arm Drill Press?
If you only drill small parts, standard hardware holes, or occasional dowels, a radial arm drill press is overkill. The extra capacity, weight, and setup time will not improve your work. A standard benchtop or floor drill press is simpler, cheaper, and more than adequate for most tasks.
Also, if your shop is small and every tool must fit against a wall, a radial arm drill press may be too large. The arm extends far from the column, and the head tilts, which means you need clearance on multiple sides. A compact benchtop or a floor press tucked into a corner is a better fit for tight spaces.
Verdict and Takeaways
A radial arm drill press is not for everyone, but it is indispensable for the right work. The Palmgren is the best choice for a production shop or a serious furniture maker who needs reliability and reach. The Grizzly G7945 is the best benchtop radial for a home shop with a solid, wide bench. The Shop Fox W1669 is a close alternative with slightly different tilt geometry.
Before you buy, measure your bench or floor space. Check the head travel and tilt range against your typical workpieces. And be honest about how often you need radial reach. If you only need it once a month, consider a drill guide or a simple jig. If you need it every day, a radial arm drill press will pay for itself in saved time and better accuracy.
