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.
A design providing precision where tapping operations on close centers is required. The Collis assembly of tap drivers and chucks allows for easy tapping operations in the "hard-to-reach" areas. This type of assembly eliminates the need for costly pulley taps.
Multiple spindles require the accuracy of precision Acme threads and the concentricity of a precisely ground O.D. and I.D. All adapters are produced to precise automotive standards to maintain maximum spindle performance and minimize tool runout.
The lock nut provides the positive positioning desired in the spindle.
Collis Tap Drivers utilize the four way split to provide maximum gripping of the tap, to minimize pull-out and to reduce down time. Dimensions follow the automotive specifications.
The square on tap shank engages with the broached square hole in the Tap Driver for a positive drive of the tap. Made from high quality steel and heat treated. Collis Tap Drivers are made to withstand the strain and abuse of production tapping operations. Tap Drivers listed are readily available from stock, sizes not listed can be quoted and supplied on request.
