At CNC Tools Depot, we supply a complete range of collets designed for superior accuracy, durability, and stability in machining operations. Collets are an essential component in CNC machining as they securely hold cutting tools or workpieces, ensuring vibration-free performance and precision results.
We offer collets from leading brands such as Korloy, Widia, Kennametal, Taegutec, ZCCCT, Kyocera, and Seco Tools. Whether you are performing milling, drilling, boring, or tapping, our extensive range of collets guarantees reliability and cost-effectiveness.
Collets are widely used across industries such as automotive, aerospace, die & mold, shipbuilding, energy, and precision engineering. Some key applications include:
Tool Holding – Ensures rigid clamping of cutting tools during milling, drilling, reaming, or tapping.
Workpiece Holding – Used in lathes and grinders for holding cylindrical workpieces with precision.
High-Speed Machining – Minimizes runout and vibration, improving surface finish and tool life.
Micro-Machining – Essential for small-diameter tools where precision clamping is critical.
We stock a wide variety of collets to suit every machining requirement:
ER Collets – Most versatile, available in a wide clamping range, ideal for milling, drilling, and tapping.
R8 Collets – Commonly used in milling machines, particularly Bridgeport-type machines.
TG (Tremendous Grip) Collets – Designed for heavy-duty machining with excellent gripping strength.
DA (Double Angle) Collets – Compact design, suitable for drilling and light machining operations.
Milling Collets – Specialized for holding end mills and milling cutters securely.
Spring Collets – Provide self-tightening action, commonly used in precision grinding.
Hydraulic & Pneumatic Collets – For automated CNC machines requiring quick-change tool setups.
✅ Global Brands in One Place – Korloy, Kennametal, Widia, Seco, Taegutec, and more.
✅ Wide Selection – ER, TG, DA, R8, and custom collets.
✅ High Precision – Ensures minimal runout for superior machining accuracy.
✅ Durability – Manufactured from high-grade alloy steel for long service life.
✅ Cost-Effective Solutions – Competitive prices with assured quality.
A collet is a clamping device used to hold cutting tools or workpieces securely in place during machining operations.
Collets provide higher precision and grip for smaller tools/workpieces, while chucks are more versatile but less accurate.
ER collets are versatile and used for milling, drilling, reaming, and tapping in CNC machines.
Most standard ER collets offer a runout accuracy of 0.005mm to 0.015mm, depending on grade.
Yes, ER collets have a flexible clamping range of about 1mm, allowing them to hold different tool sizes.
R8 collets are primarily used in milling machines (like Bridgeport) for holding end mills and drill bits.
TG (Tremendous Grip) collets are recommended for high-torque and heavy machining applications.
Collets should be replaced every 400–600 hours of use or when noticeable wear, runout, or tool slippage occurs.
Yes, high-precision collets are designed to withstand high RPM operations with minimal vibration.
Collets are widely used in automotive, aerospace, die & mold, electronics, medical device manufacturing, and general engineering.
