Techniks 32956 HSK 63A x SLN 5/8 - 3.75 Tool Holder

The Techniks 32956 HSK63A x SLN 5/8" - 3.75" Tool Holder delivers rigid, high-precision end mill clamping for CNC milling on HSK63A centers, featuring Coolblast Through-Spindle Coolant Channels for dedicated through-spindle coolant delivery and reduced runout. Designed for precision end mill retention, it uses a 5/8 in bore, provides a 3.75 in projection length, a tool-holding length of 2.09 in, with a nose diameter of 1.63 in, a body diameter of 1.89 in, an overall diameter of 2.48 in, and an overall length near 5.01 in. Constructed from hardened alloy steel (8620), it offers a H5 precision bore and AT3 ground taper accuracy, with a G6.3 balance rating at 15,000 RPM to support high-speed machining. Its primary function is precision end mill clamping with reduced runout, and it is compatible with HSK63A CNC machining centers and milling machines. This holder supports replacement, retrofit, precision machining, and preventive maintenance in aerospace, automotive, mold and die, medical component manufacturing, and other precision metalworking environments where low runout and excellent surface finishes are critical.
