Dayton Drill Press Parts: How to Find What You Need

Grainger sells a lot of industrial tools under house brands, and Dayton is one of the oldest and most trusted of them. If your Dayton drill press needs a part, the good news is that Grainger is still very much in the parts business. The challenge is that this ecosystem works differently from consumer-brand presses. You do not search by model name the way you might on Amazon or Sears PartsDirect. You search by Grainger stock number, and once you know that, ordering is straightforward. Here is how the whole system works.

A Dayton drill press is an industrial-grade benchtop or floor-standing press sold by Grainger under its Dayton house brand, sharing OEM origins with other Grainger brands such as Westward. Models include 15-inch floor presses (stock number 400H52), 17-inch floor presses (stock number 467L86), and 20-inch versions (stock numbers in the 1KEN5 through 1KEN7 range), with parts sourced through Grainger’s industrial supply network rather than consumer-retail channels.

Short answer: to find parts for a Dayton drill press, record your Grainger stock number from the machine’s ID plate, then contact Grainger at 1-800-GRAINGER or use grainger.com. Parts are sourced by stock number rather than model name, and Grainger’s industrial supply chain gives access to wear items including belts, chucks, chuck keys, and service components. Here is what you need to know.

The stock-number system

Dayton does not organize its products the way consumer brands do. There is no “Dayton model 1234” in the Craftsman 113-series sense. Instead, every Dayton tool carries a Grainger stock number printed on the ID plate, and that number is the key to the entire parts ecosystem. With it, you can search grainger.com or call Grainger’s industrial counter and often pull up a parts list or cross-reference diagram. Without it, you are guessing.

Step one, always: find the Grainger stock number on your press before anything else.

Common Dayton drill press models

The Dayton lineup covers a range of sizes that suit industrial and serious-hobbyist shops:

• 15-inch floor press (400H52): 7-1/2 inches spindle-to-column, a mid-size floor machine suited to general fabrication work.
• 17-inch floor press (467L86): Larger swing for center-of-board capacity on wider stock.
• 20-inch machines (1KEN5, 1KEN6, 1KEN7): Full floor presses with industrial-grade motors built for production and heavy shop use.

If your press has a Westward badge, note that Westward is another Grainger house brand sharing OEM sources with Dayton, so parts cross-reference applies in both directions.

What parts to expect to need

For any drill press that sees regular use, the wear items are predictable:

V-belts. These stretch and crack over time and are the most common reason a press loses power or slips. Grainger stocks V-belts by size and part number; confirm the cross-section and length from your press before ordering.

Chuck and chuck key. A worn keyed chuck is a common upgrade even on sound machines. A replacement 1/2-inch or 5/8-inch keyed chuck from a quality maker restores clean, accurate drilling, and chuck keys go missing over years of shop use.

Laser batteries. Some Dayton presses include a dual crosshair laser that runs on AAA batteries. The laser module mounts separately and simply needs fresh batteries when it dims.

Bearings and spindle components. These are longer-service items, but Grainger’s industrial supply chain can source them by specification when you provide the stock number and request a service parts diagram.

How to order

For common wear items like belts and chucks, grainger.com is the fastest path. Search by stock number or part specification, add to cart, and ship. For less common components, calling Grainger at 1-800-GRAINGER connects you to their industrial counter, where staff can pull up machine documentation and cross-reference parts by stock number. Grainger maintains documentation for Dayton machines that may not be publicly visible online.

The honest caveat

Dayton is an industrial-channel brand, not a consumer one. Documentation, diagrams, and parts depth are strong through Grainger’s system, but they require working within that system. If you are used to searching a consumer parts site by model name, the stock-number approach feels different at first. Once you have the number in hand, Grainger’s sourcing is one of the best in the business.

Dayton versus other presses for parts support

Compared to a Craftsman, the Dayton parts world is more streamlined once you know how it works, routing through a single industrial supplier rather than a patchwork of retail channels. For shops that already buy through Grainger, this is no friction at all. For home hobbyists new to industrial supply, starting at grainger.com is the right move. Our JET drill press guide and WEN drill press guide cover alternatives with consumer-channel parts and support.

The verdict

Dayton drill presses are honest, industrial-grade machines, and parts support through Grainger is solid once you approach it correctly. Record your Grainger stock number, use grainger.com or call 1-800-GRAINGER, and you have access to V-belts, chucks, keys, bearings, and service documentation. The stock-number system feels unfamiliar coming from consumer brands, but it is a cleaner route to parts once you learn it.
