Consistency and speed can be difficult to achieve in cross-hole deburring, even when the operation is performed on a CNC machine tool. One common limitation is the cutting tool. Rather than static cutting edges, tools designed specifically for cross-hole deburring tend to employ inserts that spring outward from the shank into the space created by the intersecting bore. Limited to only feed and speed rate adjustments, even the most skilled machinist might struggle to complete the operation as efficiently as possible.
