True drilling cost per panel is bit consumption + board material + machine time. Knowing it lets process engineers justify a better entry/backup board that lifts hit count and lowers unit cost. This tool models cost per panel from your inputs.
Bit cost per panel falls as hit count rises. A lubricant aluminum entry sheet or UV melamine backup that adds 15-25% hits can offset its own price and cut total unit cost - while also improving burr and hole wall roughness. Model both scenarios before choosing. See our backup board range.
| Material | Throughput Impact | Hole Quality | Cost per Panel |
|---|---|---|---|
| UV Melamine backup board | High hit count | Excellent exit burr control | $$$ |
| HDF backup board | Standard hit count | Good burr control | $$ |
| Phenolic backup board | Moderate hit count | Good for back-drill | $ |
| Lubricated aluminum entry | +20-40% stack height | Excellent micro-via quality | $$$ |
| Standard aluminum entry | Baseline | Good universal protection | $$ |
Stable feed rate and clean exits are what let you push hit count without micro-drill breakage. Pair the right board with the parameters from this tool — see our backup board range and aluminum entry boards.

What is cost per panel? Bit consumption + board material + machine time, per panel.
What is cost per hole? Total panel cost divided by holes; the unit economics of drilling.
How do I lower drilling cost? Raise hit count with better boards, or lower bit/board/machine unit cost.
What is hit count? Holes a bit drills before resharpening; higher hit count lowers bit cost.
Does a lubricant entry sheet save money? Often yes - the hit-count gain can offset its price and cut total cost.
What is the machine rate? Hourly cost of the drill line; cycle time converts it to per-panel cost.
What is cycle time? Seconds per panel; longer cycle raises machine cost per panel.
What is tool life? Total holes per bit before resharpening; the mirror of hit count.
What is drill breakage cost? Wasted bit plus scrapped panel; good support reduces both.
What is burr and why care? Exit burr adds a cleaning step; clean exits save rework.
What is hole wall roughness cost? Rough holes may need extra desmear/plating care, adding cost.
What is the difference between mechanical and laser cost? Laser micro-vias avoid bits for tiny vias but need laser capex; compare by density.
Cycle time per hole is the sum of feed time (stack height / feed rate), retract time, and table positioning. Throughput (holes/hour) is the inverse of cycle time multiplied by spindle count. A move from 2-up to 3-up stacking can increase throughput by 50% — if the entry board supports it.
Excellon — PCB drilling machines ↗
Panel drilling cost = (drill bit cost + entry board cost + backup board cost + machine time cost + overhead) ÷ good panels out. Scrap from drilling defects often dominates the cost equation. Reducing breakage and burr defects through better consumable selection frequently pays for itself within weeks.
IPC — PCB cost factors (IPC-2221) ↗
First-pass yield in drilling is driven by positional accuracy, hole wall quality, and burr height. Defect rate calculators on this site help model the impact of parameter shifts. A 1% improvement in yield on high-layer-count boards can save thousands of dollars per month.
Sierra Circuits — Back-drilling ↗
Spindle utilization (actual drilling time ÷ total shift time) is the key machine efficiency metric. Unplanned downtime for drill breakage (15–45 min per event) is the largest utilization killer. Consistent consumable quality reduces breakage frequency and improves OEE.
Posalux — PCB drilling solutions ↗
Back-drilling requires controlled-depth accuracy ±0.05 mm to remove the stub without damaging the target layer. The entry board choice matters: a dedicated back-drill entry sheet with coating provides consistent Z-reference for depth registration and protects the surface from the larger back-drill bit.
YUESHAN — Back-drill depth control guide
Drill resharpening can recover 60–80% of original tool life at 30–50% of new bit cost. The decision to resharpen depends on the number of regrinds possible (typically 3–5 for micro-drills) and the quality requirement of the target holes. Resharpening is most economical for standard-diameter drills above 0.3 mm.
