UCY
UCY
The UCY Series from TCT is a revolutionary new drill bit that offers a conventional two-flute geometry that transitions into a single- flute geometry. The result is a tool that offers four-facet point centering, lower breakage rates, better overall accuracy, improved hole wall quality, and a standard repoint design.
Find a range of common sizes offered below. Custom diameters and flute lengths are available upon request.
