NU5A Compact Scan



equipment,ltd. is pleased to introduce the new

Nordutensili NU5A Compact Scan machine, 

the first totally automatic compact spiral router bit sharpener in the world.


  • The NU5A Compact Scan will grind all types of solid carbide spiral bits
  • The first machine designed specifically to resharpen for spiral router bits
  • Compact overall size allows easy and problem-free installation
  • Two wheels mounted together, one 75mm(3") D6A9 wheel for OD grinding and one 100mm(4") D12V9 wheel for Fluting & End grinding
  • Automatic wheel measurement program activated every time the machine is switched on
  • The NU5A Compact Scan does not require a specialist to operate, very little time is needed for training on how to use the machine and the mechanical and electronic systems are easily accessible
  • What makes the NU5A Compact Scan so revolutionary is the software which, through automatic laser analysis, allows the machine to determine all the tool parameters and automatically set-up and grind the tool with angular precision better than 0,03°
  • Due to the simplicity and ease of use, one operator can operate multiple machines at the same time and take up very little space


  • Productivity: You do not have to sharpen a spiral tool on a machine designed to manufacture the tool
  • No Errors: Due to exact laser analysis of the spiral tools parameter
  • Cost savings: No operator training costs due to the simplicity of the machine
  • Safety: Due to the totally enclosed working area
