Omega Products BT40 ER Collet Chuck - ER40 - 25,000RPM - G2.5 - 80mm Gauge Length - Form AD/B

Engineered for BT40 spindle systems, the BT40 ER Collet Chuck delivers reliable, high-precision tool holding for ER40 tooling in demanding milling and drilling operations.

• BT40 compatibility: Designed to integrate seamlessly with BT40 spindles for stable, repeatable toolholding in CNC machines.
• ER40 compatibility: Accepts ER40 collets, enabling a versatile range of cutting tools without changing holders.
• High-speed capability: Operates from 15,000 to 25,000 RPM, suitable for fast material removal and efficient machining.
• Gauge length: 80 mm gauge length provides solid balance and rigidity during heavy cuts and long reach operations.
• Precision ratings: G2.5 and G6.3 precision indicate excellent concentricity and minimal runout for improved surface finish.
• Form AD/B mounting: Form AD/B geometry ensures precise seating and repeatable tool changes within BT40 tooling setups.

This BT40 ER Collet Chuck is a purpose-built solution for shops that require tight tolerances and consistent performance across a variety of materials. The combination of secure clamping, low runout, and a broad RPM range translates to cleaner cuts, longer tool life, and better overall part accuracy. Ideal for precision milling, drilling, and pocketing tasks where tool stability and finish quality matter most.
