KURATA TOOLS - Leading Manufacturer of High Precision Clamping Systems. Discover How We Help
KURATA Tools specializes in the R&D, production, and sales of high-precision clamping systems for CNC machine tools.
The Collet Chuck Holder Tool Back Pull Type is a high-performance tool holding system engineered for modern CNC machining centers, precision milling machines, and high-speed production environments. Designed to deliver superior clamping stability and machining accuracy, this precision CNC collet chuck holder ensures reliable tool retention even under heavy cutting loads.
As a professional CNC collet chuck holder manufacturer and collet chuck holder supplier, we provide advanced tooling solutions optimized for precision, durability, and flexibility across multiple machining applications.
The Collet Chuck Holder CNC Milling Tool Back Pull Type adopts an innovative back pull type collet chuck mechanism that pulls the cutting tool axially toward the spindle during tightening. This design improves tool stability, minimizes runout, and prevents interference with fixtures or machine tables.
Compared with conventional holders, the tool back pull type collet chuck provides stronger gripping force, making it ideal for high-speed milling, drilling, tapping, and reaming operations.
Our collet chuck holder factory manufactures a complete range of holders including:
ER collet tool holder systems (ER11–ER50)
ER32 tool holder, ER40 tool holder, and ER25 collet chuck
BT collet holder and BT ER collet chuck
HSK collet and SK taper compatibility
Straight shank ER collet holder options
Custom OEM collet chuck tool holder solutions
| Feature | Description |
|---|---|
| High Precision Concentricity | Concentricity tolerance ≤0.005 mm ensures minimal tool runout and precise machining. |
| Strong Clamping Force | Axial pull-back design of the back pull type collet chuck holder provides stable and uniform clamping for heavy-duty cutting. |
| Durable Material | Made from high-quality 20CrMnTi or SCM415 alloy steel, heat-treated to HRC 56–60 for superior wear resistance. |
| Dynamic Balance | Each collet chuck tool holder is dynamically balanced up to G2.5 at 25,000 RPM for high-speed CNC machining. |
| Wide Compatibility | Compatible with ER collet sizes from ER11 to ER50 and various taper types including BT, SK, CAT, and HSK. |
| Extended Service Life | Hardened and corrosion-resistant surfaces ensure long-lasting performance and low maintenance. |
