For once, the two curves point different ways
For most of 2026, carbide and bearing pricing moved together: both up, both tight. This month they separated.
Carbide paused. Ammonium paratungstate held near RMB 580,000 per tonne, well off March's peak of roughly RMB 1.52 million. That is real relief on the raw-material line — but it has not translated into availability. Cutting-tool lead times remain 12 to 20 weeks, because the tool-making capacity that absorbed the spike has not been unwound.
Bearings tightened upward. SKF and NSK standard ranges are quoting 26-week lead times, Timken 22 weeks, against 50% steel tariffs feeding the input cost. Standard-bearing price ranges that looked soft are firming as the reshoring capacity gains get absorbed.
Two categories, two playbooks
- Cutting tools — buy the dip in price, not the lead time. A lower APT print is a chance to lock volume at current prices, but only if you accept the 12–20 week delivery. Plan tooling orders against the lead time, not the spot price.
- Bearings — move before the re-price. With 22–26 week lead times and tariff pressure, the window to lock standard-bearing frameworks is closing. Treat availability, not price, as the binding constraint.
Reading the catalog matters
Both categories reward buyers who can read a specification. BBI Proferred cutting tools publish their HSS grades precisely: M2 holds red hardness to about 1000°F for general-purpose machine work, M35 cobalt adds abrasion resistance for difficult materials, and M42 super cobalt gives the best abrasion resistance and red hardness. Matching the grade to the job is how a tooling budget survives a price cycle.
On the bearing side, Timken's tapered roller line publishes single-row, double-row, mounted, and metric series with the fitting and setting guidance that lets a buyer standardize instead of substitute.

Set your reorder triggers to the lead time, not the price
When two categories move in opposite directions, a single purchasing rule stops working. Recalibrate each trigger against its own constraint. For tooling, that means ordering against a 12-to-20-week clock even though prices are soft. For bearings, it means treating 22-to-26-week lead times as the binding fact and moving the reorder point accordingly. A reorder point set from historical usage alone will not survive a lead-time change of this size. Recalculate it from current lead time, average consumption, and the cost of an expedite.
