Questions about this item

Will the 5/16" die threads need re-cutting after repeated flaring jobs?

The hardened steel dies resist thread wear; clean metal shavings after each use and store dry to maintain cutting edges for the 14 February 2025 production batch.

What stops the die set from binding during a long run of tube flares?

The fixed 5/16" pitch and single-size geometry mean alignment errors, not tool limits, cause binding first; keep tubing square and lubricated.

Does the hand tool heat up or tire the user during all-day shop use?

No powered components generate heat; the lightweight forged body and knurled handles limit fatigue during continuous 5/16" flaring sessions.
