"Heli-Flex” PCD end mills are designed for ultimate performance. All Standard end mills are configured with precisely ground PCD tips held to stringent tolerance range. It is possible to custom tailor “Heli-Flex” end mills for special applications (fig 1). The cutting edge can be designed utilizing multiple grades of diamond or even a combination of PCD/Carbide for machining ferrous and non-ferrous materials with one tool.

       • 08 Grades of PCD Material

       • High Performance Carbide Shank

       • Center Cutting End Geometry




Helical PCD tipped drills are well suited for carbon fiber reinforced plastics (CFRP) and all non-ferrous material applications. The helical flute design will allow for increased feed/speed rate, improved surface finish and increased tool life.

Special multi-facet geometries will substantially reduce or eliminate the “push through” effect or burrs on carbon fiber panel applications typically found in the aerospace industry. Our manufacturing process does not limit “Heli-Flex” drills to small diameter applications.

“Heli-Flex” drills can be tailored to optimal performance levels for all non-ferrous applications including multi-material stacks found in the aircraft manufacturing industry, cast aluminum, carbon fiber reinforced plastic, metal matrix composite, ceramic, graphite, brass, bronze and copper.

Heli-Flex Benefits

FLEXIBILITY: Standard series matched to general applications. Special applications can be configured with multiple grades of PCD or Carbide to achieve optimum results. Multi-material stack lay ups can be machined with a combination of grades on the same flute.

REDUCED COSTS: It is possible to re-sharpen, recondition and re-tip. Increased tool life 50-750 times standard carbide will lead to maximum cost savings. Minimize your inventory levels and reduce machine set up cost.

INCREASED PRODUCTIVITY: Much greater feed/speed rate than conventional tooling. Increased depth of cut and maximum material removal rate. Hard diamond matrix leads to less spindle down time and fewer tool change cycles.

ENHANCED WORK PIECE QUALITY: Improved surface finish is achieved through helical design and highly honed flute edge. Improved thermal conductivity and less material build up.
