Techniks End Mill Holder’s h5 bore tolerance ensures a tighter fit with the cutting tool shank so run-out is minimized extending tool life and improving surface finishes. Each End Mill Holder is balanced to 15,000 RPM @ G6.3. Stubby gage lengths are available when Z-axis stroke is limited. Extended gage lengths are available for long reach applications such as machining on horizontal machining centers. Rigid Reach End Mill Holders feature a tapered body design that reduces vibration and enhances rigidity and are an excellent choice when machining at extended lengths. DualDRIVE End Mill Holders are designed to work with dual-contact spindles to provide superior rigidity under heavy side loads. HSK63A End Mill Holders are manufactured to meet or exceed the H5 specification. H5 is an extremely accurate bore I.D. and provides improved T.I.R. for extended cutting tool life. H5 bore tolerance for improved concentricity and tool life Taper ground to AT3 specification for maximum spindle contact Balanced to 15,000 RPM at G6.3 Coolblast: Coolant channels in the bore direct coolant precisely to the cutting edge Effective removal of chips for faster feed rates H5 bore tolerance for improved concentricity and tool life
