Guide · Cost of Ownership
The invoice shows price per blade; the job absorbs cost per meter. This guide gives you a simple three-term method — blade price, changeover downtime, scrap — to compare blades on the number that actually reaches your margin.
A blade that costs half as much and lasts a third as long is an expensive blade. The practical form of the comparison: cost per meter equals blade price, plus changeover cost, plus scrap cost, divided by meters of in-spec cut. All three numerator terms move when you switch blade class, substrate or supplier — which is why the quotient has to be measured on your machine and your material, not assumed from a price list.
Compare like for like: geometry, substrate (tungsten carbide versus HSS), and measured in-spec life per material. The published ranges on this site are references pending final catalog — for example, Z10-class oscillating blades at $28–45 per piece or K6t-class 10-packs at $13.25 — and a price only means something once it is divided by your logged meters of acceptable cut.
Every change costs a stopped table: unload, insert, recalibrate, run a test cut. Scheduled at the end of a job it is nearly free; mid-run it stops everything downstream of the table. Blade life therefore converts directly into downtime per shift, and a blade with predictable life can beat a cheaper one that fails without warning — unplanned changes also tend to arrive at the worst moment of the run.
A dead edge discovered after lamination or printing converts a cheap consumable into an expensive panel. Replacing at the first quality sign on high-value work is part of blade economics, not perfectionism. The policy pays for itself in avoided write-offs, and the replacement interval you learn from the log is what makes it affordable.
Keep a per-blade log: material and thickness, meters or standard jobs completed, the first defect observed and where it appeared, and the date the blade came out. A few weeks of records produce a per-material replacement interval you can plan around — and that interval is the denominator in the quotient above. No instruments required, only the discipline of writing the line down at changeover.
Tiers only pay when consumption is predictable and the blade is proven stable on your material. The site's published policy:
Trial small until in-spec life is proven on your stock; then commit to the tier. Buying 50 pieces of a blade you have not metered is a discount on an unknown.
List your blades and consumption — we verify compatibility against your nameplate photos first, then quote the tier that your logged life actually supports.
