17 965 Delta Drill Press: What Owners Should Check Before Buying or Repairing

The Delta 17-965 is a 16-1/2-inch floor drill press from Delta’s long-running 17-900 family, and it is one of those machines that keeps circulating on the used market because it was built well enough to outlast its original owners. If you are looking at one, or you already own one and want to keep it running, the questions are always practical: what are its real specs, what fails on it, and can you still get parts? Here is what to check before you buy or before you start turning wrenches.

What the 17-965 is

The 17-965 is a floor-standing drill press with a 16-1/2-inch swing, part of Delta’s 17-900 series (the 17-900 and its variants share much of the same design). It uses a stepped-pulley belt drive for multiple spindle speeds, a cast-iron table that raises, tilts, and locks, a Morse taper spindle, and a keyed chuck. This is a mid-size floor machine built for woodworking and light metal, with the mass and rigidity a floor press gives over a benchtop unit. It predates lasers and digital readouts, so it is a straightforward mechanical machine, which is part of its appeal for owners who like to fix their own tools.

Why owners keep them

Let me be direct about the draw. A floor-standing 16-1/2-inch Delta has real presence: enough swing for wide work, enough spindle travel for most tasks, and the heavy iron that keeps holes straight. Delta’s build quality on these was a step above bargain machines, and because the design is simple, there is very little to go wrong that a patient owner cannot service. That combination, capable size plus fixable simplicity, is why the 17-965 holds its following.

What to check before buying or repairing

Run through these on any 17-965:

• Spindle and quill. Turn the spindle by hand for smoothness, check quill side play, and check chuck runout. A little runout is usually a tired chuck; a lot can mean a bent spindle.
• Spindle return spring. A weak or broken spindle return spring is a common issue on older presses. It is serviceable, but confirm the quill returns smoothly.
• Belt and speeds. Check the belt condition and that all speed positions line up on the pulleys. Set belt tension per the manual.
• Table hardware. Confirm the table clamp handle, raising handle, table bracket, and alignment pin all work and lock. Missing table hardware is common and worth noting.
• Switch and motor. Test the toggle switch and confirm the motor runs smoothly. Note the voltage and follow proper grounding, avoiding long extension cords.

Parts support and the honest caveat

Here is the practical picture. Delta went through ownership changes over the years, so some model-specific parts for the 17-900 series can be intermittent to source, with certain numbers going in and out of stock. The everyday wear items, belt, chuck, key, and the return spring, are generic or well-documented, so routine service is easy. For anything specific, keep the model number handy and use Delta’s parts service and the owner community. Buy a 17-965 for the solid machine it is now, rather than assuming every internal part is a quick order.

Tooling and replacement parts

Keep a 17-965 running with standard tooling. A quality 5/8-inch keyed drill chuck with an MT2 arbor restores accuracy, a fresh drill press V-belt smooths the drive, and a drill press spindle return spring fixes a weak quill return. Keep a spare drill press chuck key and add a drill press vise. Confirm the taper before ordering an arbor.

The verdict

The Delta 17-965 is a solid buy and worth repairing when the castings are sound and the machine is complete, because it pairs a capable 16-1/2-inch floor-press size with a simple, fixable mechanical design. Before you commit, check the spindle, quill, return spring, belt, table hardware, switch, and motor, and confirm the table locks and the quill returns cleanly. Weigh the one caveat, that some model-specific parts can be intermittent to source, while wear items are easy. Keep the manual and model number, fit a good chuck and belt, and this old Delta floor press will keep working for a long time.

Takeaways:

• The Delta 17-965 is a 16-1/2-inch floor drill press from the 17-900 family, a simple, fixable mechanical machine.
• Owners value its floor-press size, rigidity, and the ease of servicing a straightforward design.
• Check the spindle, quill, return spring, belt, table hardware, switch, and motor before buying or repairing.
• Wear parts are generic; some model-specific parts can be intermittent, so keep the model number handy.

FAQ

What are the Delta 17-965 specs? It is a 16-1/2-inch-swing floor drill press from Delta’s 17-900 series, with a stepped-pulley belt drive, multiple spindle speeds, a cast-iron tilting table, a Morse taper spindle, and a keyed chuck.
