Which Delta 12-Inch Drill Press Belongs in Your Shop?

The Delta 12-inch drill press, most often the model 11-990, is one of those benchtop machines that shows up constantly on the used market and for good reason: it was a well-built, sensibly sized press that Delta sold to homeowners and woodworkers for years. A 12-inch swing hits a genuine sweet spot, big enough to center a hole in a 12-inch board, small enough to sit on a bench, and Delta’s name means the parts and manuals are still findable. If you are weighing a 12-inch Delta against a smaller 10-inch or a bigger machine, the choice comes down to swing, power, and what you actually drill. Here is how to decide.

The Delta 12-inch drill press (model 11-990) is a benchtop drilling machine with a 12-inch swing, a 1/3-HP 115V induction motor, 5 belt-driven speeds from 620 to 3,100 RPM, a 1/2-inch chuck, a tilting cast-iron table, an adjustable depth stop, and a column-mounted work lamp and utility tray, built for light-to-general drilling in wood, plastic, and thin metal.

Short answer: the Delta 12-inch 11-990 belongs in your shop if you want a compact benchtop press with a bit more swing and table than a 10-inch, for woodworking and light metal. It is a light-duty machine (1/3 HP, belt-change speeds), so step up to a floor press for heavy or large-bit work. On the used market, a clean 11-990 with Delta parts support is a solid value. Here is the detail.

What the 12-inch 11-990 is

The 11-990 is a benchtop press built around a 12-inch swing, meaning 6 inches from the bit to the column, enough to center a hole in a 12-inch workpiece. Its specifications tell you exactly who it is for:

• 1/3-HP 115V induction motor drawing about 6.5 amps: light-to-general power.
• 5 speeds from 620 to 3,100 RPM, set by moving the belt on the pulleys.
• 1/2-inch keyed chuck and a 2-3/8-inch stroke.
• Tilting cast-iron table (about 8-1/2 by 9-7/8 inches) with slots for clamping, and side edges for angle drilling.
• Column-mounted work lamp and utility tray, thoughtful touches Delta included.

It is a woodworking-friendly light-duty machine, not a metal-shop workhorse.

Who it suits

The 12-inch Delta suits the woodworker or general DIYer who wants more than the smallest benchtop press but does not need a floor machine. The extra swing over a 10-inch press lets you reach the center of wider boards, and the tilting table and depth stop handle angled and repeat drilling. For furniture work, general shop tasks, and light metal, it is well matched.

It does not suit heavy metal drilling, large-diameter bits, or production work. The 1/3-HP motor and belt-change speeds are the honest limits.

Setting it up right

• Mount it solidly to a sturdy bench so it cannot rock.
• Square the table by checking a rod in the chuck against the table with a square in two directions.
• Set the belt speed for the bit and material: slower for larger bits and metal, faster for small bits in wood.
• Use the depth stop for repeatable hole depths.
• Check the return spring so the quill returns smoothly.

The honest flaws

Light-duty power. At 1/3 HP, large bits in hardwood will bog it. Match your bits to the machine.

Belt-change speeds. Five speeds set by moving the belt, no dial.

Short stroke. A 2-3/8-inch quill stroke means deep holes need the table repositioned.

Discontinued. The 11-990 is a used-market machine now, so buy on condition and completeness.

Buying a used 11-990

Because these are bought used, inspect carefully: spin a bit to check runout, pull the quill through its full stroke for smooth travel and return, start the motor and listen for a clean run, and check the table, column, and castings for damage. A cracked belt or worn chuck are cheap, expected fixes; a cracked casting or dead motor are not. Delta parts support runs through Delta’s parts network and Sears PartsDirect by the model and type number, so a sound machine needing only wear parts is worth restoring. See our Delta drill press replacement parts guide for the ordering flow.

How it compares

Against a 10-inch Delta such as the Delta 11-985, the 12-inch 11-990 adds swing, a larger table, and more speeds for a small step up in size. Against a current benchtop like the variable-speed WEN 4212T 10-inch or the larger WEN 4214T 12-inch, the Delta trades a speed dial and a fresh warranty for cast-iron simplicity and used-market value. If you need heavier capacity, a floor press like the Delta 17900 is a different class. Choose the 12-inch Delta for a well-made light-duty benchtop; choose a WEN for variable speed out of the box.

The verdict

The Delta 12-inch drill press (11-990) belongs in your shop if you want a compact, well-built benchtop machine with a useful 12-inch swing for woodworking and light metal. Its 1/3-HP motor, 5 belt speeds, tilting cast-iron table, work lamp, and utility tray make it a pleasant light-duty press, and its limits, modest power, belt-change speeds, and a short stroke, are exactly what you would expect. On the used market, a clean example with Delta parts support is genuine value. If you drill large bits, heavy metal, or need deep strokes and variable speed, step up to a floor press or a current variable-speed benchtop instead.

Frequently asked questions

What are the specs of the Delta 11-990 drill press? A 12-inch swing, a 1/3-HP 115V induction motor (about 6.5 amps), 5 speeds from 620 to 3,100 RPM, a 1/2-inch chuck, a 2-3/8-inch stroke, a tilting cast-iron table around 8-1/2 by 9-7/8 inches, an adjustable depth stop, and a column-mounted work lamp and utility tray.

Is the Delta 12-inch drill press good for metal? For thin metal and small-to-medium bits at the correct slow speed, yes. Its 1/3-HP motor is not built for large-diameter bits or heavy continuous metal drilling, so match your bits to the machine.

What does a 12-inch swing mean on a drill press? It means the distance from the bit to the column is 6 inches, so the machine can drill to the center of a 12-inch-wide workpiece. Swing is always twice the throat distance.

Can you still get parts for a Delta 11-990? Yes, common wear items like the belt, chuck, switch, and spring are available through Delta’s parts network and Sears PartsDirect by the model and type number, plus matched generics. Record the numbers before ordering.

How many speeds does the Delta 11-990 have? Five, ranging from 620 to 3,100 RPM, set by moving the belt between pulley steps rather than a variable-speed dial. Use slower speeds for larger bits and metal, faster for small bits in wood.

Should I buy a used Delta 12-inch drill press? If it is complete and in good condition, it is a solid light-duty benchtop value. Check spindle runout, quill travel, motor sound, and the castings, and budget for a belt and possibly a chuck.

What is the difference between the Delta 11-990 and a 10-inch Delta? The 11-990’s 12-inch swing gives more reach and a larger table than a 10-inch press like the 11-985, along with more speeds. Both are light-duty benchtop machines; the 12-inch simply handles slightly wider work.
