Delivery in time can be guranteed since we have our own factory,8. Strict inspection during the process of manufacturing. Products advantages 1. axis precision, can reach 20000rpms speed, but will not increase the pressure on the axis of the machine. Double tool life, improve the core of life, high quality surface polishing. 2. Accurate and precise concentricity can extend the life of cutter, the coolant can be directly through the chuck flow tool, products amounted to or exceeded the ANSI standard. 3. Have high flexibility of the ER collet series, does not need to be replaced chuck, and it can be used for drilling, reaming and milling and tapping screws processing program, also do not affect the accuracy. Handle attached to DIN coolant holes; balance has chuck, axis and tool life compared with the general chuck durable, productivity higher; thread through hole design allows the coolant is flowing, when to stop using available bolt blocked via holes. 4. ER Collet series using has heat treatment and grinding the special stainless steel material manufacture, has high precision, high clamping force and persistence collet can clip to a specific range of specifications. Can be used in boring, milling, drilling, tapping hole etc..
