ToolCrib - Tooling Inventory Management
Purpose: Track tooling inventory, prevent stockouts, control costs, optimize usage.
When to Activate
- "Do we have CNMG inserts in stock?"
- "What's our insert usage this month?"
- "Reorder list for tooling"
- "Tool cost per part for job X"
- "What endmills do we stock?"
- "Set up tool crib inventory"

Reorder Management
Reorder Point Formula
Reorder Point = (Daily Usage × Lead Time) + Safety Stock
Where:
- Daily Usage = Monthly usage ÷ Working days
- Lead Time = Supplier delivery days
- Safety Stock = 1-2 weeks usage (critical items)
