Professional letter stamp set

The Capri Tools CP23100-316L provides 27 individual stamps covering uppercase A to Z plus an ampersand. Each punch is machined from Chrome Vanadium steel with differential heat treatment for two distinct hardness zones. The set arrives in a heavy-duty storage case for organisation.

Hardened stamping and striking ends

The stamping face reaches 62 HRC to keep edges sharp and produce clean imprints on leather, wood, copper, brass, aluminium and mild steel. The hammering end is tempered to 42 HRC to absorb repeated blows without deforming. Engraved sizing and identification on the side facing the user simplify selection and orientation.

Suited for metalwork and leathercraft

This kit serves hobbyists and professionals who need precise, repeatable letter marking on softer metals and organic materials. Buyers requiring lower-case letters, numeric stamps or larger character sizes should look at alternative sets. The Proposition 65 notice indicates chemical exposure risk during use.

Questions about this item

Will the 62 HRC stamping ends need replacement if they dull over time?

The 62 HRC stamping ends are heat treated to keep edges sharp and are not designed for user replacement; the set is intended to last through repeated use on leather, wood, copper, brass, aluminum and mild steel.

What limits continuous stamping before the 42 HRC hammering ends show wear?

The 42 HRC hammering ends are differential heat treated to absorb repeated hammer strikes, so the practical limit is the operator's endurance rather than a defined wear threshold.

Does the chrome vanadium steel generate noticeable heat during all-day stamping sessions?

No significant heat builds up in the stamps themselves during prolonged use; the 42 HRC ends absorb impact energy and the steel remains cool to the touch.
