DYNABRADE Cone Or Plug Grinder (Double Extension) - 53532
-
1 hp, Straight-Line, 18,000 RPM, Rear Exhaust, 3/8"-24 Spindle Thread.
- Includes 3/8"-24 Male Threaded Adapter (53610)
-
Extension Grinders allow operator to extend into work pieces and reach lengthy distances.
-
Extension length of 8-3/8? allows longer reach than competitive models! Extensions are constructed of steel for maximum durability.
-
Designed for minimal vibration. Extensions do not spin during tool use, so continuous tightening is not needed (as with some one-piece shaft-type extensions).
-
Tools can also be fitted with optional Buffing Pads, optional collets and inserts, plus optional Cone/Plug Wheels. (Note: Speed of tool must not exceed maximum operating speed of accessory.)

Maintenance Tips
-
Use clean, dry compressed air: Moisture and contaminants can damage the air motor and reduce tool life. Install a filter/regulator system whenever possible.
-
Lubricate daily: Add pneumatic tool oil to the air inlet before use to keep internal vanes and bearings operating smoothly.
-
Maintain correct operating pressure: Run at the recommended air pressure (typically 90 PSI) to prevent premature wear and maintain performance.
-
Inspect extension assemblies regularly: Check the double-extension shaft for looseness, wear, or damage before each use. Steel extensions are durable but should be inspected frequently.
-
Check abrasive accessories before use: Never use cracked, damaged, or improperly rated cone or plug wheels. Ensure accessory RPM ratings meet or exceed the tool's 18,000 RPM maximum speed.
-
Keep exhaust ports unobstructed: A blocked rear exhaust can reduce power and increase operating temperatures.
-
Inspect air hoses and fittings: Repair leaks immediately to maintain consistent airflow and tool performance.
-
Clean after every shift: Remove grinding dust and debris from the housing, spindle, and air inlet area to extend service life.
-
Store in a dry environment: Protect the grinder from moisture and corrosion when not in use.
