ER25, ER32, and ER40 collets and HSK63 tool holders for CNC routers and machining centers, from IMS and X-Edge.

Collet condition affects cut quality more than most people expect — a worn or mismatched collet introduces runout that shows up as inconsistent edge finish or premature bit wear, often misdiagnosed as a problem with the bit itself rather than the holder. Hardened steel construction holds concentricity better over repeated tool changes than lower-grade alternatives.

HSK63 holders add balance and vibration control at higher spindle speeds, which matters most on tight-tolerance work where spindle chatter shows up directly in the finished surface.
