Powermatic DS20 20" Disc Sander 2hp, 1PH, 230V - PM9-1791276

Powermatic DS20 20" Disc Sander 2hp, 1PH, 230V

Disc sanders have always been useful in woodworking. The Powermatic DS20 20" Disc Sander takes that concept with its brute power, 20” diameter disc and an array of user-friendly features. Near the top of the feature list is a huge, articulated cast iron table, making it clear that the DS20 20" Disc Sander is a serious tool.

The DS20 20" Disc Sander comes with a 2 horsepower, 1 phase, 230V motor. Powermatic motors are rated using a continuous duty cycle for a true representation of its power rather than the “peak” or “max developed” figures. The motor is big, heavy and built to operate efficiently and smoothly for years. The heavy platen that backs the abrasive is driven directly from the motor shaft, ensuring a very consistent 1,720 RPM.

The DS20 20" adhesive-backed discs attach to a precision-machined steel platen that is mounted directly to the motor shaft using a large-diameter flange for maximum strength and alignments. This mass of this 9/16” thick by 20” diameter steel platen dissipates heat while resisting distortions and vibrations. Its sheer mass adds a flywheel effect that further smooths the sanding process.

Because the platen is made from steel, scraping spent abrasive discs from its surface is much easier without fear of damaging the softer materials often used to make the platen on other sanders. The inertia developed by the heavy platen and motor mean that the Disc Sander will take a long time to “spin down” after it is shut off. The DS20 features an easy-to-use hand brake that applies a specially formulated disc to the rear of the platen to safely stop it in seconds.

A full shroud below the table does a good job of evacuating dust from the lower half of the disc before it has a chance to come above the table. The shroud terminates in a 4” diameter port that makes connecting standard dust collector hose simple. We recommend a dust collector with a minimum 600 CFM capacity.

Maintenance Tips

• Clean regularly: Remove sanding dust and debris from the disc, table, and motor after each use to ensure smooth operation and prevent buildup.
• Inspect the sanding disc: Check the disc for wear, damage, or uneven sanding, and replace it when necessary to maintain consistent performance.
• Lubricate moving parts: Apply oil or lubricant to the disc arbor, bearings, and other moving components to reduce friction and prolong the lifespan of the machine.
• Check belt tension: Inspect the drive belt for wear, and ensure it is properly tensioned for smooth and consistent power transfer.
• Monitor motor and electrical components: Inspect the motor and wiring for any signs of wear or damage to ensure safe operation.
• Tighten fasteners: Periodically check all bolts and screws to ensure they are tight, preventing vibrations and ensuring stability during use.
• Check alignment: Ensure that the sanding disc is properly aligned with the table to achieve even sanding and avoid uneven wear
