A Quick Change Rubber Collet is a soft, flexible workholding collet designed for rapid replacement and non-marking grip of delicate, finished, or thin-wall components. It is ideal for automation lines, inspection stations, grinding, polishing, and light machining applications where frequent size changes, speed, and surface protection are essential.
A Friction Collet is a specialized workholding collet that grips components using high-friction contact surfaces rather than relying only on elastic spring force. It is ideal for smooth, hardened, plated, or polished components that tend to slip in standard steel collets, and is widely used in CNC turning, grinding, automation, and mass production applications.
A Multi Bore Collet is a special-purpose workholding collet designed with two or more bores to clamp multiple identical components simultaneously in a single cycle. Commonly used in CNC lathes, SPM machines, transfer lines, and automation systems, it increases productivity, reduces cycle time, and is ideal for high-volume production of small components.
An SDC Collet is a single-taper precision tool-holding collet designed to deliver strong gripping force with low runout. It is commonly used in CNC machining centers, drilling and tapping machines, and SPMs where high rigidity, repeatability, and accurate tool holding are required.
A Bearing Collet is a precision workholding collet designed to securely hold bearing components such as inner rings, outer rings, races, and assembled bearings during grinding, turning, inspection, and assembly operations. It provides uniform clamping, high concentricity, and distortion-free holding, ensuring bearing accuracy, performance, and long service life.
An F Series Collet is a heavy-duty workholding collet used on manual lathes, CNC lathes, and capstan or turret lathes. It provides strong gripping force, high rigidity, and reliable accuracy for medium to large diameter components, making it an ideal replacement for jaw chucks to achieve better precision and faster cycle times.
A W-Series Collet is a high-precision, draw-in type workholding collet commonly used on cylindrical grinders, tool and cutter grinding machines, milling fixtures, and inspection setups. It offers excellent concentricity, high rigidity, and repeatable accuracy, making it ideal for precision grinding and finishing operations.
The NBC Collet is a high-precision tool holding component designed for CNC, milling, and turning applications.
Provides superior clamping strength for consistent and accurate machining operations.
Made from high-grade hardened steel for exceptional durability and long service life.
Ensures minimal runout, improving cutting accuracy and surface finish quality.
Reduces vibration during machining, enhancing tool life and operational stability.
Compatible with NBC collet chucks and various tool holding systems.
Easy to install, remove, and maintain in workshop and industrial environments.
Perfect for machinists seeking precision, rigidity, and reliable performance.
