BC Mill Chuck is a performance milling chuck designed for reduced harmonics and improved grip force with on-size cutting tools. Sealed by design with optional Jet-Blast for coolant applications.
Our testing has shown 100% improvement over popular German competitor's "heavy milling" hydraulic chuck.
CAT40-BC050-0283 slipped @ 155 ft/lbs
Competitor's Hydraulic slipped @ 70 ft/lbs
The test arbor is a carbide end mill blank that measure 0.4998.
We feel testing with carbide provides "real life" holding power assessment.
We shot a video to show how we tested and tightened the chucks.
