Powermatic PM2800B Drill Press Parts: A Complete Sourcing Guide
The Powermatic PM2800B is the current-generation flagship in the Powermatic drill press lineup — the latest evolution of the 2800 series with refinements to the variable speed system, improved depth readout, and updated table mechanics. If your PM2800B needs a part, you’re in the best possible position: an active manufacturer, full documentation, and parts in stock.
How the PM2800B Differs From the 2800
The PM2800B is an updated 2800 with several improvements:
- Refined variable speed control — smoother speed dial with better RPM stability under load
- Updated digital depth readout — more accurate display with reset function
- Improved table lock mechanism — more positive lock at any height
- Updated quill feed handles — improved ergonomics
- LED work light — integrated, same location as the 2800
Core specs remain:
| Specification | PM2800B |
|---|---|
| Swing | 20 inches |
| Spindle travel | 6 inches |
| RPM range | 170 – 3,000 RPM |
| Motor | 1-3/4 HP variable speed |
| Spindle taper | MT3 |
| Chuck capacity | 5/8 inch |
| Table | 20” × 20” cast iron, T-slots |

Variable Speed Drive: Service and Parts
The PM2800B’s variable speed drive is electronically controlled. Key service considerations:
- No V-belts to replace — drive system is electronic; routine belt service is not required
- Control board — if the speed display behaves erratically, runs at wrong speed, or fails to control, the control board is the part to order; source only through Powermatic for the correct board revision
- Speed sensor — the motor has a speed feedback sensor; if spindle speed doesn’t track the dial, the sensor or board may be involved
Chuck and Arbor: MT3 Is the Interface
The PM2800B’s spindle is MT3. For any chuck work:
- MT3 chuck arbor assembly — the correct spindle interface for the PM2800B
- JT33 keyed chuck — mount on the MT3 arbor for a complete assembly
- Chuck key — keep a dedicated spare; the PM2800B ships with one but a spare stored on a nearby magnetic strip is worth having
To remove the factory chuck: lower the quill, insert a drift through the quill ejection slot, and tap with a mallet. Support the chuck with your other hand.
Quill Return Spring
The torsion spring assembly in the quill return is a Powermatic-specific part. Order by part number from the PM2800B parts diagram through Powermatic or eReplacementParts.com.
Symptoms of spring failure:
- Quill returns slowly after each plunge
- Quill doesn’t return to full up position
- Quill drops under its own weight when feed handles are released
Table Height and Lock Mechanism
The PM2800B’s rack-and-pinion table mechanism is improved over earlier 2800 versions. If the table won’t lock securely:
- Check the lock bolt threads for wear or contamination
- Clean and lubricate the rack
- If the rack teeth are worn, the rack is a Powermatic-supplied replacement part
For maximum precision, re-square the table to the spindle after any table height or tilt adjustment.
Workholding for the PM2800B’s Large Table
The 20” × 20” T-slot table handles serious workholding setups:
- 4-inch precision drill press vise for most precision metalwork and woodwork
- Palmgren drill press vise for production runs and heavy stock
- T-slot step-block clamping sets for plate work
Bolt the vise to the T-slots rather than just resting it on the table — at 1-3/4 HP, the PM2800B has the torque to shift an unbolted vise on large cuts.
Built-In Lighting
The integrated LED work light is a Powermatic assembly. If it fails, order the replacement through Powermatic. A supplemental gooseneck LED light positioned from the side adds lighting angles that the built-in unit can’t cover.
Pre-Order Checklist
- ✅ Serial number (essential for PM2800B parts orders — board revisions change)
- ✅ Machine registered with Powermatic
- ✅ Part number from PM2800B parts diagram
- ✅ MT3 taper confirmed for chuck/arbor work
- ✅ Chuck key pilot size measured if replacing key
- ✅ Drive system symptom documented for control board orders
Final Thoughts
The Powermatic PM2800B is the best drill press Powermatic currently makes. It’s designed for serious production work and backed by a manufacturer that stands behind its machines. Parts are available, service is accessible, and the machine itself will outlast most of what you put in front of it.
