High Performance Drilling in Carbon Fiber (CFRP)


RobbJack tool distributor Chicago

Solid PCD-Tipped W-Point Drill, designed specifically for Carbon Fiber Composites.

This powerful, newly developed tool had all the features needed to do the job right, including:

  • A solid polycrystalline diamond tip that outperforms diamond coating in materials with high plastic content, maintaining its edge longer
  • A sharp outer edge that cleanly shears the material without delamination, uncut fibers or fiber pullout
  • An innovative W-point geometry that supports the material as it pierces through
  • Tool life 25 times longer than traditional carbide drills in CFRP applications—and can be extended even further with re-sharpening



    When drilling carbon fiber–reinforced polymer (CFRP) wing spars, an aircraft manufacturer struggled with poor quality cuts and expensive scrap until switching to RobbJack’s new Solid PCD W-Point drill.

    The Problem

    Prized for its high rigidity and strength-to-weight ratio, CFRP is notoriously difficult to machine without delamination, uncut fibers and fiber pullout. One manufacturer was going through 25 carbide drills to make one ship set of wing spars, scrapping many very expensive parts along the way. The process was intolerably costly and unstable.

    Then RobbJack took on the challenge.

    The Result

    • The RobbJack Solid PCD-tipped W-point was the only tool that could meet the manufacture’s exacting design and performance standards, cutting over 4000 clean holes in tolerance; other tools struggled to get 160 holes.
    • It completely stabilized and streamlined a previously difficult and wasteful process—secondary operations were no longer required
    • Just one PCD-tipped W-point bit was sufficient to make a complete ship set of wing spars—a process that previously had gone through 25 lesser drills

    The RobbJack Solid PCD-Tipped W-Point consistently achieved clean, precise cuts. Plus, freed from the hassle and time of replacing worn drills, the manufacturer achieved increased capacity & throughput.

    AirPRO Dust Evacuation Nut for CNC Routers


    Stop losing time and money on dust clean-up. AirPRO Dust Extracting Nut from Techniks removes virtually all dust from nested cutting operations. Simply replace your collet nut with the AirPRO. Collet and toolholder sold separately.airpro_exp

    • Greatly reduces airborne dust and dust on the floor
    • Cleaner workpiece and safer work environment
    • Ese with ER32, ER40 or SYOZ25 collet chucks

    Problem: dust left behind after processing.
    Dust removal can become a time-consuming health and safety problem if the dust extraction on your CNC router is inadequate. The new AirPRO from Techniks removes dust from nested cutting operations so it never has a chance to accumulate. Sawdust is ventilated directly into the CNC dust collection hood by the AirPRO, leaving a cleaner cut and clean air behind.

    NOTE: AirPRO must be used with on-size precision ER collets and tightened to torque specifications (above) using a tightening stand, torque wrench and proper adapter or warranty becomes invalid.

    Ingersoll Cutting Tools Chicago – Grooving, Parting and Turning

    Grooving, parting and turning with 4 cutting edges with chip former.
    Ingersoll Cutting Tools Gold-Flex Quad Groove Line

    Ingersoll is pleased to officially introduce Gold-Flex, the new product line that features a 4-edged insert for multifunctional operations. Suitable for grooving, parting, lateral turning and chamfer machining, Gold-Flex provides excellent performance, repeatability and economy.

    Gold-Flex inserts feature a high-positive chip former that enables machining in multiple applications while providing excellent chip control in plunging and lateral turning operations. The result is excellent surface finish as the chips are broken and moved away from the work piece.

    The clamping system features a side torx screw and 3 cGoldFlexPicPR_240wontact points for stability and durability under demanding machining conditions. Insert indexing and changing is simple and accurate, and combined with the 4 cutting edge feature makes Gold-Flex an economical and efficient tooling system. This unique clamping design also protects the cutting edges that are not in use. Thus, if one or more of the edges are broken, the insert can simply be indexed to a new edge without adversely affecting the insert seating position.

    Gold-Flex is available in widths from .020” to .125” (.5mm – 3.18mm). Lead angles and full radius inserts are also available as standard items. All inserts are available in grade TT9080, a versatile grade suitable for machining a wide variety of materials.

    For more information on Gold-Flex, please contact General Cutting Tools, your Ingersoll Cutting Tools sales representative located in Chicago.
