Ridgid DP15501 15-Inch Floor Drill Press: Specs, Capacity, Parts, and Owner Notes

The Ridgid DP15501 is a 15-inch floor-standing drill press sold through Home Depot under the Ridgid brand, covering the main requirements of a small-shop floor press: a 1/2 HP motor, 12 speeds from 300 to 3,100 RPM, a 12 by 12-inch cast-iron table, and a 15-inch swing. It is a current-production machine with active warranty support, and it occupies a specific position in the floor press market: more capable than an entry-level 10-inch benchtop, less industrial than a 17-inch or larger floor press, and priced for the hobbyist or light-production shop. This guide covers the actual specifications, what each one means in use, and what owners commonly note.

Specifications: 1/2 HP motor, 8 amps, 120V, 12 speeds (300 to 3,100 RPM via step-pulley belt drive), 15-inch swing (7.5-inch throat depth), 3-3/4-inch spindle travel (quill travel), 5/8-inch chuck capacity, 12 by 12-inch cast-iron table, total assembled height approximately 56.7 inches, width 11.65 inches, depth 22.24 inches, approximate weight 225 lbs. The machine ships disassembled and requires assembly.

Straight answer: the DP15501 is a solid mid-range floor press for general wood and light metal drilling. Its main practical limits are the 3-3/4-inch spindle travel (limiting for deep holes without repositioning) and the step-pulley speed system (no variable speed; speed changes require stopping the machine and moving the belt). Both are typical of machines in this price class.

What the specs mean in practice

15-inch swing and throat depth

The 15-inch swing means the spindle can reach 7.5 inches from the column face, which accommodates panels and boards up to 15 inches wide for center-line drilling. For off-center holes in wider stock, the workpiece must be repositioned or the hole must be within the 7.5-inch reach.

12 speeds (300–3,100 RPM)

12 belt-driven speeds via a step-pulley system cover the main drilling range for wood and soft metal. 300 RPM at the low end suits large Forstner bits and large bits in hard material; 3,100 RPM at the high end suits small bits in soft material. Speed changes require opening the belt cover, moving the belt to the appropriate step combination, and closing the cover — a one-minute task.

3-3/4-inch spindle travel

3-3/4 inches (95mm) is adequate for drilling through standard board thicknesses and most dowel and joint applications. For deep hole drilling (through thick stock, or for deep pockets), this is a limiting spec; repositioning the table up to reduce the gap between the chuck and the workpiece is the workaround.

5/8-inch chuck capacity

The 5/8-inch chuck accepts bits and accessories up to 5/8-inch shank diameter, which covers the full range of standard drill bits and most Forstner bits. Spade bits and most brad-points in common sizes also fit.

Cast-iron table and workholding

The 12 by 12-inch cast-iron table has slots for clamps and vises. Owners commonly note that standard drill press clamps do not always engage the slots cleanly; checking slot compatibility before buying workholding accessories saves time. A Palmgren 3-inch drill press vise and a WEN DPA423 cross-slide vise are commonly used accessories with this class of machine.

Parts and warranty

The Ridgid DP15501 is sold at Home Depot and carries Ridgid’s 3-year limited service warranty covering defects in workmanship and materials, including brushes, chucks, motors, switches, cords, gears, and batteries. Parts are available through Ridgid’s authorized service center network (call 1-800 on warranty card for nearest location) and through third-party parts sites including PartsWarehouse (partswarehouse.com, which lists DP15501 parts by key number from the machine’s parts diagram). The UWM-hosted parts diagram PDF is also available online with the full numbered parts list.

For a replacement chuck: a 5/8-inch keyed chuck with JT33 arbor is a common fit on JT33 spindles (confirm the spindle taper from the machine’s documentation). A universal ratcheting chuck key covers a lost key.

Owner notes

Owners of the DP15501 commonly note three things:

1. Table clamp compatibility: Standard clamps may not fit the table slots perfectly; confirm slot dimensions before buying workholding accessories.
2. Assembly: The machine ships in a box and requires assembly; allow an hour or more. The process is straightforward but the machine is heavy, so having a second person helps for the column-to-base step.
3. Belt access: Speed changes require access to the belt; the cover opens without tools, but the step requires stopping the machine, which is expected and not a defect.

The honest flaws

Two honest flaws. First, the 3-3/4-inch spindle travel is the most commonly cited practical limitation; a machine with 4.5 or 5 inches of travel would cover more applications without table repositioning. Second, the step-pulley speed system means no speed adjustment while running — you must stop, move the belt, and restart for each speed change, which adds time in mixed-material work.
