Step Bore Finishing

Accu-Cut size-adjustable step bore finishing tools can simultaneously process two concentric diameters.

Our precision step bore tools can process two concentric diameters simultaneously holding the tightest tolerances.

Accu-Cut has diamond honing tool solutions for your step bore applications. Our finish step bore tooling will help you improve concentricity between bores to achieve superior geometry and surface finish.

• Adjustable precision step bore tools can achieve less than 0.003mm concentricity between two bores
• When followed by blind bore and through bore finishing tools, 0.000020”roundness, 0.000015” straightness, and 4 Ra surface finish can be achieved
