descriptionThere are several ways to drill holes larger than 3.2mm diameter。
With “step-drilling” or "pre-drilling",spindle load can be significantly reduced,resulting less spindle damage & better swarf draft.
With a special designed point angle of 165°，standard back-up plate 1.5mm thicknrss can still be used.
