The 5C Collet Chuck provides enhanced precision compared to a standard 3-jaw chuck, delivering secure, repeatable workholding for high-accuracy machining. When paired with the appropriate 5C collet, it can accommodate round, square, and hex-shaped stock, expanding workholding flexibility and improving repeatability on demanding projects. Note: 5C collets are not included and must be purchased separately. .sc-prod-desc{ color:#111; line-height:1.7; font-family:system-ui,-apple-system,Segoe UI,Roboto,Helvetica,Arial; font-size:15px; } .sc-prod-desc p{ margin:0 0 12px; color:#333; opacity:.95; } .sc-note{ margin-top:10px; padding:12px 14px; border-radius:14px; border:1px solid rgba(0,0,0,.10); background:rgba(245,158,11,.10); color:#111; } .sc-note strong{ font-weight:800; }
