Description

Built for the Stone Market, Not Adapted From Something Else

The Samurai ST-358 is a heavy-duty pneumatic wet stone grinder built in Japan. It runs a 570W motor at 10,000 RPM - the output range where diamond cup wheels cut granite, quartz, and engineered stone efficiently without bogging down. Fabrication shops run this tool for edge shaping, profile cuts, sink cutouts, seam leveling, and surface prep before polishing begins.

The center water feed integrates directly into the spindle, keeping cooling water exactly where the diamond is in contact with stone. The rear exhaust design routes exhaust air away from the work surface, which matters when you are making a clean cut and need clear line of sight.

Specs and Features

  • 570W motor - consistent power output under load on hard materials including Absolute Black granite and engineered quartz
  • 10,000 RPM at 16 CFM / 90 PSI - the operating range for efficient material removal and edge shaping on stone
  • 5/8-11 arbor - U.S. standard thread for diamond cup wheels, disc attachments, and core drill bits
  • Center water feed - integrated cooling delivers water at the contact point; cleaner and more consistent than an external hose setup
  • Rear exhaust design - exhaust routes away from the work area and operator line of sight
  • Maximum 5-inch disc diameter - covers the full range of cup wheel sizes for granite and stone fabrication work
  • Adjustable handle - sets to right or left-handed grip
  • Easy-grip, easy-twist on/off knob
  • Replacement parts available separately - service the tool without replacing the whole unit
  • 1-year warranty against manufacturing defects

How It Fits Into a Complete Fabrication Setup

The grinder comes first. Edge profiling, cutouts, surface damage removal, seam leveling - the ST-358 handles the material removal stage before polishing begins. Once the shape is right and the surface is clean, switch to the ST-235 wet stone polisher for the progressive grit sequence through to a finished gloss.
Pair the two tools and you have the full fabrication workflow in two pneumatic tools, both made in Japan, both supported with available ST-358 replacement parts. Buy direct or through one of our authorized dealers.
Frequently Asked Questions
What is the RPM of the Samurai ST-358?
10,000 RPM at 16 CFM / 90 PSI. This is the operating range for efficient material removal on granite, quartz, marble, and engineered stone.
What size diamond cup wheel fits the ST-358?
The ST-358 accepts diamond cup wheels and disc attachments up to 5 inches in diameter via a 5/8-11 arbor thread - the standard connection for U.S. stone fabrication diamond tooling.
Is the ST-358 pneumatic or electric?
Pneumatic. It requires compressed air at 90 PSI / 16 CFM. Shops with a compressor will find pneumatic preferred for wet stone work - no overheating risk, lighter weight, consistent RPM under load.

Yes.Replacement parts are available directly through samuraiairtools.com. OEM parts maintain the tool's performance specs and keep the warranty intact.
What materials can the ST-358 grind?
Granite, quartz, marble, porcelain, and other hard natural and engineered stone materials. The 570W motor handles the full range of hard stone without loss of cutting speed.
