Description

Why the ST-235 Is the Industry Standard for Granite Shops

The Samurai ST-235 is a pneumatic wet stone polisher built in Japan. It has been the reference tool in stone fabrication for years - copied by competitors, trusted by fabricators who run it daily on granite, quartz, marble, and engineered stone.

This is not a general-purpose angle grinder with a water attachment. The ST-235 was designed specifically for the demands of a fabrication shop: wet environment, high cycles, full grit progression from 50 through 3,000. It runs at 5,000 RPM at 90 PSI / 16 CFM with a 5/8-11 arbor for complete compatibility with standard diamond polishing pad systems.

Specs and Features

  • 5,000 RPM at 90 PSI / 16 CFM - right in the range for granite edge polishing
  • 5/8-11 arbor thread - compatible with all standard diamond polishing pads and backer systems
  • Built-in brass lubrication port - oil directly into the motor without disassembly; keeps the motor running at full power over time
  • Integrated water fittings - standard pneumatic and water connections; ships with hoses included
  • Adjustable handle - sets to right or left-handed grip for working different edge profiles
  • Easy-grip, ambidextrous on/off twist knob
  • Parts and repairs readily available - no waiting months for a replacement component
  • 1-year warranty against manufacturing defects
Built for Professional Fabrication
Pneumatic tools run cleaner in wet shop environments than electric. No overheating shutdowns in the middle of a production run. Lighter weight reduces fatigue on edge detail work. The ST-235 pairs directly with the Samurai ST-358 wet stone grinder - grind with the 358, polish with the 235. Need to replace a component?

Frequently Asked Questions
What RPM does the ST-235 run at?
5,000 RPM at 90 PSI with a 16 CFM air requirement. This covers the working range for granite edge polishing through a full diamond pad progression.
What pad size does the ST-235 use?
4-inch and 5-inch diamond polishing pads via the standard 5/8-11 arbor thread. Compatible with all major diamond pad systems used in granite fabrication shops.
Is the ST-235 compatible with standard diamond polishing pads?
Yes. The 5/8-11 arbor is the U.S. industry standard for stone diamond tooling. The ST-235 works with the full range of diamond pads available from fabrication suppliers.
Does the ST-235 work on quartz and marble as well as granite?
Yes. Variable speed and water-fed operation make it suitable for granite, quartz, marble, porcelain, and other natural and engineered stone materials. Adjust pad pressure for different stone hardnesses.
How do I oil the ST-235 motor?
The built-in brass port on the tool allows direct lubrication without disassembly. Add air tool oil regularly - this is the single most important maintenance step for extending the life of any pneumatic tool.
issues caused by flaws in the product's manufacturing process, not normal wear and tear or damage from misuse: not adding sufficient oil, or excessive grinding is not a MFG defect
