Asmita Industries manufactures a wide array of collets and related accessories for CNC, VMC, lathes, grinding machines, and more:
-
Machine Collets: Including CNC VMC Machine Collets, Milling Machine Collets, and Traub Machine Collets (DIN standard).
-
Collet Types: They produce specific designs such as Expanding Collets, Sleeve Collets, Crimping Collets, Diamond Collets, 5C, 16C, R8, TG, DA, and SDC collets.
-
Collet Chucks: The product line also includes various collet chuck systems like Hydraulic Rotary and Stationary Collet Chucks, Pneumatic Collet Chucks, and expanding collet mandrels.
-
Other Accessories: They also deal in associated items like collet adapters and machine fixtures.
Key Features of collet:
-
High Clamping Force: The tapered design translates axial tightening force into immense radial clamping force.
-
Precision and Repeatability: Collets provide high accuracy, excellent concentricity (low runout), and repeatable positioning of the held object.
-
Self-Centering: They reliably self-center the tool or workpiece, which aids in stable, vibration-free machining.
-
Limited Clamping Range: A specific collet usually has a very narrow range of diameters it can effectively clamp. This means multiple collets are needed to hold a variety of sizes.
Common Applications of collet :
Collets are widely used across various industries where precise and secure holding is essential.
-
Metalworking and Woodworking: They are a primary method for holding cutting tools (like drill bits, end mills, and reamers) in machine tools such as lathes, milling machines, routers, CNC ,VMC, HMC machine
-
Automobile industries: Split collets are used to hold engine valves under constant spring pressure. For high Production . Wheel Balancing mandrel for inspection of alloy wheel accuracy.
-
Jewelry: In jewelry making, a collet refers to the band or flange in which a gem is set. Bati collet and collet spindle.
-
Pump industries: Used for making of submersible pump parts, like Baul, Gunmetal bush, brass bush, S.S. Sleeve, Upper Lower, Impeller. we manufacturing collet chuck for clamping a submersible part

-
Pharma industries: we manufacturing a crimping collet For crimp a Medicine bottle, perfume bottle.
Types of Collets:
There are many industry-standard designs, with the ER collet system being the most widely used globally. Other types include:
-
ER Collets: The most popular general-purpose collet (e.g., ER-8 to ER-50 series), known for their versatility and ability to collapse slightly to cover a small range of sizes.
-
5C Collets: Primarily used for work holding, they often feature external threads at the rear for drawing the collet closed, allowing material to pass through the spindle.
-
R8 Collets: Developed by Bridgeport for milling machines, these fit directly into the machine taper itself and require an exact match between the collet and tool shank diameter.
-
Traub collet: Traub collet is widely used in CNC machine. For clamping a job. A15,A20,A25,A32,A42,A60,A80 collet series also know DIN collet.
-
Expanding collet: this Collet is used for Clamping internal diameter.
