SW ER Collets are engineered to provide exceptional clamping accuracy and long-term durability for modern CNC machining applications. Every collet is manufactured using premium alloy spring steel and precision-ground to ensure uniform elasticity, stable gripping force, and minimal runout.
Each ER collet undergoes precision heat treatment, CNC grinding, and strict quality inspection to guarantee excellent dimensional accuracy and repeatability. The optimized slot design provides even clamping pressure around the cutting tool, reducing vibration and improving machining stability.
Whether used for milling, drilling, reaming, tapping, engraving, or high-speed machining, SW Cutting ER collets deliver reliable performance under demanding production conditions.
Product Features
Manufactured with strict tolerance control to ensure excellent runout accuracy and repeatable positioning.
Made from high-quality alloy spring steel with optimized elasticity and fatigue resistance.
Even pressure distribution provides secure tool holding while minimizing vibration.
Long Service Life,Advanced heat treatment increases hardness, wear resistance, and durability under continuous production.
Precision grinding ensures smooth surfaces and protects the spindle and tool holder.
Compatible with all standard ER collet chucks manufactured according to DIN 6499 standards.
