Floating Holders Floating Holders Full floating action that compensates for the misalignment of the tool to the work piece. Lateral float is 1/32" from centerline. Precision action of the holder provides the drive for the closest tolerance work. These holders are self-centering and internal float members are shielded from the intrusion of chips and dirt. All steel working surfaces as well as shank and holder hole are heat treated to maintain precision of spindles and tools. Morse tapered hole holders when used with the Split Sleeve Reamer and Tap Drivers offer tooling adaptation, simplified floating action minimizes downtime and maintenance requirements.
