Step Bores

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

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

Accu-Cut has diamond tool solutions for your step bore applications.  Our step bore tools will help you improve concentricity between bores and, when followed with blind bore and step bore tools, can achieve superior geometry and surface finish.

• Adjustable 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
