Big Kaiser HDC toolholder

Big Kaiser has expanded its HDC jet-through hydraulic chuck line to include the BCV interface and additional inch sizes. HDC toolholders are designed for high-precision five-axis machining. With maximum speeds of 35,000 rpm and clamping range of ¼" to ½", they are suitable for many applications in the automotive, aerospace, medical, and die and mold industries.

A thread feature allows for convertible coolant delivery between jet-through coolant and center-through coolant. According to the company, Jet-through hydraulic chucks are ideal toolholders for finishing applications, which benefit from improved coolant delivery. The coolant flows through the end of the toolholder and angles toward the cutting tool tip to improve surface finish and tool life.

HDC toolholders require only one hex key wrench to clamp or loosen the cutting tool, easing tool changes and eliminating any need for special equipment. The toolholder provides 0.00012" total indicator runout (TIR) at 5×D.

  • The Knob Problem

    The retention knob is an unmistakably critical component of the machining process. However, the tightening of the knob itself can lead to the toolholder not seating securely in the machine. You may be losing tool life to knob tightness without even knowing it.

  • Too Small To Touch

    Hummingbird takes on machining work that is too small for most shops to handle. In fact, Hummingbird tries not to handle it either. To accurately machine the tiniest parts, this shop relies on processes that are as hands-off as possible.

  • The Humble Pull Stud

    I’ve said that the toolholder is the least appreciated element in many milling processes, but the pull stud (or retention knob) is perhaps the least appreciated component of the toolholder.
