Annular-cutter life cannot be reduced to one guaranteed hole count.
Use the comparison as a controlled buying record. It should identify the application, the exact tool variants, the evidence reviewed and every field still requiring supplier confirmation.
Start with the hole and assembly requirement
Define the cutter identity and acceptance endpoint.

Compare cutting structure and operating behavior
Record material, thickness, scale and interrupted features.

Confirm machine, interface and workholding
Log diameter, depth and holes completed by application group.

Frequently Asked Questions
How many holes will a cutter make?
There is no universal count; it depends on stated conditions.
What shortens life?
Material, depth, instability, runout, cooling, feed and damage can all contribute.
Does TCT always last longer than HSS?
No universal conclusion applies across all work.
When should a cutter be replaced?
At the documented wear, damage, quality or behavior endpoint.
Can worn cutters be reground?
Only when the exact construction and condition are approved for professional regrinding.
How should suppliers be compared?
Use identical material, holes, machine, method and replacement endpoint.
Conclusion
Tool life is a measured application result. A useful record explains not only how long a cutter ran, but under exactly which conditions and why it was retired.
