When a finishing job calls for a pronounced, continuous grain pattern rather than aggressive stock removal, the Dynabrade 13450 Dynisher Air-Powered Abrasive Finishing Tool provides the speed and power needed for controlled surface refinement. Its 1 HP pneumatic motor delivers added power for sustained finishing, while the 2,800 RPM free speed produces a deeper, longer grain pattern on the work surface. This combination is particularly useful for refinishing stainless steel sinks, kitchen countertops, fabricated panels, and other visible metal surfaces where grain direction and appearance matter.
The Dynabrade 13450 uses a 3/4-inch wheel arbor and is configured for compatible abrasive belts, conditioning discs, and flap wheels measuring up to 5 inches in diameter. It is an appropriate setup for the optional Dynabrade 92938 Dynacushion pneumatic wheel, which measures 5 inches in diameter by 3-1/2 inches wide. With a maximum airflow requirement of 41 SCFM and operation at 90 PSIG, the tool should be connected to an air system capable of maintaining the specified pressure and flow while the Dynisher is running.

Applications:
- Stainless steel fabrication — establishing and restoring directional grain patterns on panels, enclosures, and finished assemblies.
- Commercial kitchen equipment — refinishing stainless steel sinks, countertops, worktables, and visible food-service surfaces.
- Architectural metalwork — blending and graining railings, trim, panels, and decorative stainless steel components.
- Metalworking and weld finishing — conditioning areas around welds and matching repaired sections to the surrounding surface pattern.
- Industrial maintenance and restoration — renewing scratched or worn metal surfaces on equipment, fixtures, and fabricated components.
FAQs:
- Q: What type of finish does the Dynabrade 13450 produce?
A: Its 2,800 RPM speed supports a deeper, longer in-line grain pattern on the work surface. The final appearance also depends on the abrasive type, grit, contact pressure, and direction of tool movement. - Q: Does the Dynabrade 13450 include the pneumatic wheel?
A: The 13450 is the finishing tool, and the 92938 Dynacushion pneumatic wheel is listed as an optional accessory. The 13460 Versatility Kit is the separate configuration that includes the 13450 tool, pneumatic wheel, air chuck, abrasives, grease gun, grease, and gear oil. - Q: What air supply does this Dynisher require?
A: The tool operates at 90 PSIG and has a listed maximum airflow of 41 SCFM. Use a compressor and air line capable of maintaining that pressure and airflow at the tool inlet during operation. - Q: What abrasives can be mounted on the 13450?
A: The tool supports compatible abrasive belts, conditioning discs, and flap wheels up to 5 inches in diameter. Confirm the arbor fit, dimensions, and maximum operating-speed rating before mounting any accessory. - Q: How should the optional Dynacushion pneumatic wheel be inflated?
A: Inflate the wheel only enough to hold the abrasive belt without slippage. Excessive inflation can produce chatter marks on the finished surface.
