- ✓Tool guidanceControl entry condition, runout and overhang before the drill reaches full depth.
- ✓Chip evacuationMatch chip formation, coolant delivery and cycle to material behavior.
- ✓Breakthrough controlReview exits near weak walls, intersecting holes and finished faces.
- ✓Bore evidenceAgree what diameter, depth, position and straightness must be recorded.
06 / DESIGN FOR MANUFACTURING
Design Decisions That Improve Process Stability
Resolve access, datum and inspection questions before manufacturing release.
Provide a stable entry
A flat, supported entry improves guidance and reduces walk.
Define the bottom
Separate drill-point depth from required full-diameter depth.
Allow chip escape
Avoid blind geometry that traps chips without an evacuation strategy.
State functional intent
Identify whether flow, alignment, sealing or fastener access controls the bore.

What qualifies as deep-hole drilling?+
A hole is commonly treated as deep when depth is several times diameter, but the practical threshold depends on tool, material and acceptance needs.
Do you support gun drilling?+
Yes, when geometry and bore requirements justify the route; final capability is confirmed during review.
Can you drill small-diameter deep holes?+
Potentially. Diameter, depth, material, entry condition, straightness and inspection method must be reviewed together.
How are deep holes inspected?+
Methods can include gauges, depth checks, CMM position, borescope review and flow or functional testing.
