No. A spring-wire specification and a cutting-tool qualification address different requirements. Test candidates against workpiece, thickness, diameter, support length, wear and impact conditions.

Ideal elastic buckling mainly depends on modulus, section and effective length. Hardness is a separate indicator related to indentation and wear and cannot guarantee resistance to misalignment or shock.

A rotational reading also contains roundness, support and surface effects. Do not treat it automatically as centerline straightness; define a method and evaluation length matching the drawing.

It may reduce binding while weakening lateral support. Check alignment and installation distortion before balancing friction against guiding stiffness.

It gives an ideal elastic critical load under concentric compression. Initial curvature, eccentricity, clearance, yielding, fatigue and dynamic effects require separate margin and application testing.

Yes, if hole burr, diameter, position or process force exceeds the acceptance limit. Structural survival and acceptable-part production are different criteria.

Review substrate support, treatment temperature, thickness-related clearance changes and tip geometry. Establish the actual benefit with a controlled comparison under common conditions.

Provide pin, bushing and die drawings, workpiece and stack details, speed and lubrication, hole-quality targets, existing damage evidence, quantities and timing. Separate unresolved items for prototype verification.
