PERFORMANCE. • Double margin construction design stabilized the drill for greater hole accuracy and improved surface finish in final hole. • Minimized delamination at hole entry/exit. • Manufactured exclusively with Di-NAMITE coating for even wear, extended tool life and improved finishes. PRECISION. A test was conducted of our CFRP drill to determine the necessity of coating when drilling Carbon Fiber material. Fifty holes were drilled using a special size .190” CFRP drill. The tool’s design produces acceptable quality holes; but as shown in the photos, early edge wear on the uncoated drill resulted in holes with frayed edges. The diamond coated drill produced all 50 holes with little to no fraying and edge wear was 38% less than the uncoated drills. The geometry of the 8 Facet drill with the Di-NAMITE coating is a necessity for additional tool life and productivity when manufacturing Carbon Fiber material.
