Omega Products' BT40 Shrink Fit Chuck with Front Face Coolant is engineered for BT40 milling applications where strong, repeatable clamping and rigid performance matter. It securely holds cutting tools with minimal runout, helping you achieve precise finishes at speed while withstanding the rigors of high-speed machining.

Designed for demanding operations, this chuck incorporates integrated front coolant channels to actively cool the cutting edge during high-speed work (up to 25,000 RPM). It adheres to BT MAS403 (JIS 6339) Form AD/B standards and is balanced to G2.5 at 25,000 RPM, featuring a precise 4.5-degree engagement angle for stable, accurate toolholding. The specification set includes 14 mm and 120 mm measurements, reflecting its compact yet capable profile.

• Front Face Coolant Channel Integration: Delivers coolant exactly to the cutting zone for efficient heat removal, preserving tool life, reducing thermal distortion, and maintaining accuracy during heavy cuts at high speeds.
• BT MAS403/JIS 6339 Form AD/B Balanced to G2.5 @ 25,000 RPM: Ensures minimal vibration and consistent runout at top milling speeds, delivering reliable performance and smooth finishes across tough materials.
• Shrink-Fit Clamping for High Rigidity and Quick Tool Changes: Provides uniform, secure tool holding with strong clamping force, reducing runout and enabling faster, repeatable setups in busy shops.

This combination of direct coolant cooling, precise high-speed balance, and dependable shrink-fit clamping translates to longer tool life, fewer reworks, and more predictable part quality. It helps streamline setups, lowers downtime, and supports consistent productivity across a wide range of milling tasks.
