How often is production stopped because of an out of stock cutting tool?
As tool designs become more specialized, the sources of supply become more fragmented and further away from the point of consumption (e-commerce, drop-shipping) the chances of this happening become greater.
Let’s divide MRO into three distinct categories:
1. MISSION CRITICAL CONSUMABLES are the cutting tools, abrasives, coolants and other supplies that are essential for production and will cause it to be stopped if not available. They also cannot be easily substituted.
2. MISSION CRITICAL DURABLES are primarily the toolholders, cutting tool bodies or other devices that hold mission critical consumables. They are purchased once and should last indefinitely. If they need to be replaced, it is probably because of a catastrophic event, which will buy a little time to get another one.
3. EVERYTHING ELSE are the tools and supplies that are price but not time sensitive. They can also be easily substituted from local sources. Examples would be AA batteries or HSS jobber drills. They may be supplied on a contract, but if you ran out you could easily find equivalents locally.
Those items that fall into the first category must have a different supply strategy than the rest to prevent production interruptions.
