High Speed Steel Spiral Reamers specially developed to size engine valve guides after installation.
 
These reamers have a 25mm pilot that is smaller than the reamer diameter. This pilot is inserted into the valve guide and is used to centre the Reamer and guide it during operation. This garantees straight and concentric holes.
 
These Reamers are compatible with both Cast Iron and Bronze Alloy Guides.
 
All Reamers are 180mm long
