The Young Cycle 36-piece combination set (YC607) includes 27 letters (A–Z plus &) and 9 numbers (0–8) — 36 pieces in all, for jobs that need both letters and numbers.
Chrome-vanadium steel (CRV/6150), hardened to 58–62 HRC.
Character heights run from 1.0mm to 10.0mm, with square shanks from 6.35mm to 12.70mm. One set covers both letters and numbers, which suits mixed alphanumeric marking without buying two separate sets; if the content changes frequently and you want a whole row in one strike, consider the YC610B interchangeable steel type kit. Young Cycle is a steel stamp manufacturer in Taiwan, producing in our own Taichung plant since 1986, OEM / ODM welcome.
