An R8 Collet is a precision tool-holding collet designed for R8 spindle milling machines, commonly used on Bridgeport-type mills. It provides accurate centering, strong gripping force, and quick tool changes for holding end mills, drills, and cutters.

A Double Cone Collet is a precision collet featuring front and rear tapered surfaces that enable uniform radial clamping. This design delivers high concentricity, strong gripping force, and minimal runout, making it ideal for both tool holding and workholding applications where accuracy and stability are critical.      

An Expanding Collet, also known as an internal gripping collet or expanding mandrel, is a workholding device that clamps components from the inside diameter. When actuated mechanically, pneumatically, or hydraulically, it expands uniformly to grip the bore, ensuring excellent concentricity and secure holding without causing external deformation.    

A Thada Collet is a traditional heavy-duty workholding collet commonly used on Indian automatic lathes, capstan lathes, turret lathes, and SPM machines. It is designed for strong gripping force, rugged durability, and economical mass production, making it ideal for applications where long service life and reliability are prioritized over ultra-fine accuracy.

A Drill Collet is a precision tool-holding collet used to securely hold drill bits, reamers, taps, and straight-shank tools with higher accuracy and grip than conventional drill chucks. It is commonly used on lathes (tailstock), drilling machines, milling machines, CNC machines, and SPMs where low runout, firm holding, and consistent drilling accuracy are essential.

A Sliding Head Collet is a high-precision workholding collet used on sliding headstock (Swiss-type) CNC lathes. It supports the bar close to the cutting zone, minimizing deflection and vibration and enabling tight tolerances, superior surface finish, and high productivity, especially for long and slender components.      

A Bar Feeder Collet is a precision guide and gripping collet used in CNC bar feeding systems to support, center, and stabilize bars during automatic feeding into CNC lathes. It ensures smooth bar movement, reduced vibration, and consistent machining accuracy, especially at high spindle speeds.

A Crimping Collet is a precision forming tool used in perfume and cosmetic packaging machines to uniformly crimp aluminum caps onto glass bottles. It ensures leak-proof sealing, a clean finished appearance, and consistent, repeatable crimping quality.

A Straight Collet is a cylindrical, straight-bore tool-holding collet used to hold straight shank tools such as drills, reamers, end mills, taps, and grinding tools. It provides direct axial holding without a taper, making it suitable for drilling, grinding, inspection, and light machining applications.      

A Milling Collet is a precision tool-holding collet used to securely clamp end mills, slot drills, reamers, and cutters in milling machines and CNC machining centers. It ensures accurate centering, strong gripping force, and vibration-free cutting for improved surface finish and extended tool life.

A Hydro Reduction Sleeve is a precision adapter sleeve used inside hydraulic tool holders to reduce the bore size for holding smaller diameter tools. It provides excellent concentricity and vibration damping, allowing a single hydraulic holder to accommodate multiple tool sizes while improving machining accuracy, flexibility, and cost efficiency.

A Carbide Collet is a high-performance workholding collet made entirely from tungsten carbide or featuring carbide gripping surfaces. It offers exceptional wear resistance, high gripping force, and long service life, making it ideal for high-volume production, abrasive materials, and applications where standard steel collets wear out quickly.

A Diamond Collet is a specialty workholding collet featuring a diamond-coated or diamond-grit gripping surface for exceptional grip and extreme wear resistance. It is ideal for high-volume production and smooth or hardened materials where standard steel collets tend to slip or wear quickly.      

A DA Collet is a single-angle, heavy-duty tool-holding collet designed for drilling, milling, and tapping operations. It delivers strong gripping force and high rigidity, making it well suited for SPM machines and CNC machining centers requiring reliable, slip-free tool holding.

A TG collet (Tapping Collet) is a heavy-duty tool-holding collet designed for high-torque applications such as tapping, drilling, and reaming. It provides strong gripping force and high rigidity, making it ideal for operations where ER collets may slip. The TG series is DIN 6499 / ISO compatible.

An OZ Collet is a heavy-duty tool-holding collet designed for milling, drilling, and tapping operations. It provides strong gripping force and high rigidity, making it ideal for SPM machines and CNC machining centers where reliable, slip-free tool holding is required.

An SK Collet is a single-taper, heavy-duty tool-holding collet designed for drilling, tapping, reaming, and milling operations. It provides strong gripping force, high rigidity, and slip-free performance, making it ideal for SPM machines and CNC machining centers.      

A 3J Collet is a heavy-duty workholding collet used in automatic lathes, capstan lathes, turret lathes, and SPM machines. It delivers strong gripping force, durable construction, and reliable performance for medium-diameter, repetitive production jobs, making it well suited for Indian machine shop applications requiring consistent and rugged holding.

A Die Grinder Collet is a precision tool-holding collet designed to securely clamp rotary burrs, mounted points, grinding stones, polishing tools, and carbide burrs in electric or pneumatic die grinders. It provides a firm grip, low runout, and safe, stable performance during high-speed operations.

A Pull Stud Collet is a precision retention component used in CNC tool holders to securely engage the pull stud (retention knob) with the machine drawbar. It ensures reliable tool clamping, accurate tool positioning, and safe operation at high spindle speeds in BT, CAT, HSK, and ISO tool holder systems.
