Diamond Tool Life

What this topic covers

Why useful life depends on workpiece, loading, thermal conditions and acceptable finish.

Core engineering ideas

Tool life ends when wear changes dimension, finish, force or process stability beyond an acceptable limit.

Longer nominal life is not always better if a tool cuts too slowly or unpredictably.

Useful comparison requires consistent workpiece and process conditions.

System tradeoffs

Diamond is not ideal for every material; chemical wear can make cubic boron nitride or conventional carbides better choices in some ferrous applications.

Quality and verification

Tool qualification uses wear, finish, dimensional stability, force and failure-mode evidence rather than hardness alone.

Lifecycle perspective

Refurbishment, retipping and recovery can preserve the value of tool bodies and diamond-bearing material.
