This enables us to slap our promise of “Higher Performance. BIG Kaiser manufactures our shrink fit holders to the highest standards with the highest quality materials. In dual contact, we also offer ER collet chucks, hydraulic chucks, shrink fit holders, shell mill holders, end mill holders, modular adapters, turning tools for MTC’s, integral milling cutters, holders for rigid tapping and much more!Īnd since we are on the topic, when it comes to shrink fit, it’s indeed true that as a whole, they offer high clamping forces, low runout, and a small nose diameter to reduce clearance issues. We’re certainly partial to the overall rigidity, precision and repeatability of BIG-PLUS®, but understand that there’s a place for all of these interfaces – which is why we offer them.īIG Kaiser offers virtually all of our tool holding systems in all three major dual contact designs, such as our well-known collet chucks based off of the New Baby Collet, and our heavy duty milling chucks. Each of the systems above has its fans and detractors, but overall, each does a great job for what it was intended to do.

Across the board, dual contact tooling offers superior rigidity, accuracy and repeatability when compared to conventional systems.

Because the BIG-PLUS® spindle system gets so much of our customers’ attention and interest, people often forget that BIG Kaiser offers an extensive line-up of other popular dual contact solutions, most notably HSK & BIG CAPTO.
