Under the right conditions, a precision boring operation can correct for a drilled hole that is slightly out of location. That's one of the pieces of practical advice in "A Word about Boring Heads,” a short technical article by Criterion Machine Works. Boring equipment such as boring tools and heads are one of Criterion's specialties. The company knows a lot about boring operations and has captured some of this knowledge and wisdom in several articles on its web site.
For example, the article mentioned shows that the key to precision boring as a fix for an out-of-location whole is the ability of a boring head with single-point tool to remove more stock from one side of the hole than the other.
A companion piece, "A Word about Boring Tools," offers similar insights and recommendations. Its discussion about the importance of keeping the cutting edge of the boring tool on the exact centerline of the hole is clear and well-illustrated.
