Ritter R131 Triple Spindle Horizontal Boring Machine - 1" Centers

Built for shops that demand precision and repeatability, the Ritter R131 horizontal borer offers single, double, or triple spindle boring capability in one dedicated machine. Stile and rail boring setup features are engineered to minimize costly errors and rejected parts while keeping production moving efficiently. Like all Ritter machines, the R131 is proudly designed and manufactured in the USA.

How the Ritter R131 Works

A pneumatic clamp holds the workpiece securely against the table throughout the boring cycle, which is activated by a foot pedal for hands-free operation. Index stops, bed height, and depth of cut are all fully adjustable, giving operators complete control over every bore. The triple spindle gear head with 1″ spindle centers makes this machine equally capable for simple single-hole jobs or complex multi-spindle applications.
