Delta 16-1/2 Floor Drill Press: Setup, Capacity, and Support

All Posts floor drill presses Noah Carter Last updated on April 15, 2026

The Delta 16-1/2 floor drill press, usually the model 17-965, is one of the classic full-size Delta presses, and it is a machine that rewards an owner who understands it. A 16-1/2-inch swing on a cast-iron floor column, a 3/4-HP motor, and a wide belt-speed range make it capable of real woodworking and metal drilling. But like any floor press, it drills its best only when it is set up correctly, used within its capacity, and kept serviceable. If you own one or are eyeing a used example, here is the practical guide to setup, capacity, and support.

The Delta 16-1/2 floor drill press (model 17-965) is a full-size floor-standing drilling machine with a 16-1/2-inch swing, a 3/4-HP 120/240V motor, a 5/8-inch chuck, a rack-and-pinion tilting cast-iron table, 16 belt-driven speeds from roughly 200 to 3,000 RPM, and a quill stroke near 4-7/8 inches, built for general-to-heavier drilling in wood and metal.

Short answer: the Delta 16-1/2 floor press is a capable general-purpose machine for a shop with the floor space. Set it up by leveling and stabilizing it, squaring the table, and matching belt speeds to the job; work within its 5/8-inch chuck capacity and 4-7/8-inch stroke; and get parts through Delta’s network and Sears PartsDirect by model and type number. It is an excellent used-market floor press. Here is the detail.

What the 17-965 is

The 17-965 is a full-size floor drill press. Its specifications explain its reach:

16-1/2-inch swing (8-1/4 inches bit-to-column), centering a hole in a 16-1/2-inch workpiece.
3/4-HP 120/240V motor, wired for either voltage, with power for large holes in hardwood and general metal.
5/8-inch chuck for bigger bits than a benchtop machine.
16 belt-driven speeds from roughly 200 to 3,000 RPM, a wide range for wood and metal.
Quill stroke near 4-7/8 inches, long enough for deep holes.
Rack-and-pinion tilting cast-iron table and an external depth stop.
Low runout, around 0.002 inch, for accurate drilling.

Setting it up right

Floor presses reward careful setup:

Level and stabilize. Set it on a flat floor and stabilize the base so it cannot rock. Bolting it down helps for heavy work.
Square the table. Put a rod in the chuck and check it against the table with a square in two directions; adjust the table until true.
Set the belt speed. Use the speed chart: slow for large bits and metal, fast for small bits in wood. With 16 speeds, you can dial in the right RPM for almost anything.
Set the depth stop for repeatable and blind holes.
Check the return spring for smooth quill return, and adjust tension if needed.

Working within its capacity

Understanding capacity keeps the machine happy and safe:

Chuck capacity is 5/8 inch, so bits with shanks up to that fit directly; larger bits need reduced shanks.
The 3/4-HP motor handles large Forstner bits and hole saws in wood and general metal, but is not a production metalworking motor. Slow down and let it cut.
The 4-7/8-inch stroke covers most holes in one pass; deeper holes need the table repositioned.
The tilting table handles angle drilling; clamp the work for anything but the lightest holes.

The honest flaws

Belt-change speeds. Sixteen speeds are generous, but they are set by moving the belt, not a dial.

Floor space and weight. It is a heavy floor machine to place and move.

Used-market condition. No warranty on a used unit; condition is everything.

Stroke shorter than newer models. At about 4-7/8 inches, it is shorter than the 6-inch stroke on the current 18-900L.

Parts and support

Parts for the 16-1/2 Delta come through Delta’s parts network and Sears PartsDirect, keyed to the model and type number, covering belts, chucks, springs, pulleys, and switches, plus matched generics for belts and chucks. Because it is a well-known machine, wear parts are generally findable. Record the model and type before ordering. Our Delta drill presses models, parts, and support guide and used Delta drill press guide cover the inspection and ordering flow.

How it compares

Against the current Delta 18-900L, the 16-1/2 (17-965) is the simpler used-market machine: similar power and swing, but the 18-900L adds a laser, a longer 6-inch stroke, an auto-tensioning belt, and a five-year warranty. Against the Delta 17900 (17-900), it is a close sibling in the same floor-press family. Against a benchtop like the variable-speed WEN 4212T, the Delta 16-1/2 is a heavier, more capable class at the cost of size. Choose the 16-1/2 Delta for floor-press capability and used-market value; choose the 18-900L for current features and warranty, or a benchtop for light work.

The verdict

The Delta 16-1/2 floor drill press (17-965) is a capable, well-built general-purpose machine that drills its best when you level and stabilize it, square the table, and use its 16 belt speeds to match the job. Work within its 5/8-inch chuck capacity and 4-7/8-inch stroke, keep it serviceable through Delta and Sears PartsDirect parts, and it handles woodworking and general metal for decades. Its trade-offs, belt-change speeds, floor space, used-market condition, and a shorter stroke than the newest models, are typical of the class. For a shop with the floor space that wants proven cast-iron capability, it is an excellent used-market floor press.

Frequently asked questions

What are the specs of the Delta 16-1/2 floor drill press? A 16-1/2-inch swing, a 3/4-HP 120/240V motor, a 5/8-inch chuck, a rack-and-pinion tilting cast-iron table, 16 belt-driven speeds from roughly 200 to 3,000 RPM, a quill stroke near 4-7/8 inches, and a spindle runout around 0.002 inch. It is the model 17-965.

How many speeds does the Delta 16-1/2 drill press have? Sixteen belt-driven speeds from roughly 200 to 3,000 RPM, set by moving the belt between pulley steps. The wide range covers slow metal drilling and fast small-bit work in wood.

Is the Delta 16-1/2 floor press good for metal? Yes, for general metal drilling. Its low speeds, 3/4-HP motor, and cast-iron mass handle steel within reason. Use a slow speed for large bits, a center punch, and steady feed. It is not a dedicated production machine.

Can you still get parts for the Delta 17-965? Yes, wear items like belts, chucks, springs, and switches are available through Delta’s parts network and Sears PartsDirect by model and type number, plus matched generics. Record the numbers before ordering.

What is the chuck capacity on the Delta 16-1/2 drill press? It has a 5/8-inch chuck, so bit shanks up to 5/8 inch fit directly. Larger-diameter bits need reduced shanks. That capacity is typical for a full-size floor press of this class.

Does the Delta 16-1/2 floor press run on 240V? The 17-965 motor is wired for 120/240V, so it can run on either supply. Confirm the wiring configuration on your specific machine before connecting it.

How does the Delta 16-1/2 compare to the 18-900L? Both are floor presses. The current 18-900L adds a laser, a longer 6-inch stroke, an auto-tensioning belt, an 18-inch swing, and a five-year warranty, while the 16-1/2 (17-965) is the simpler machine commonly found on the used market.
