Keyless Drill Chucks with thru-hole for EDM

• There are the ones having a thru-hole from the tapered hole to the inside diameter.
• Since the cutting tools and/or electrodes can be inserted up to the top face of the spindle taper, it is useful for the electric discharge machines.
• All the parts are precision-made and hardened enough, and, moreover, the outside is totally enclosed type, all of which enduring an outstanding durability of the chuck.
• The run-out accuracy is less than 0.0020 inch that is equal to Precision Class (Silver). The accuracy is kept for a long time.

* ◆The Taper angle is the same as JT.NO.1, but taper length is shorter than standard JT.NO.1.
  The detail must be inquired to us.
* ◇Production on order.
* Diameters in the above are the maximum thru-hole diameters.
