    Indexable Gun Drills

    These drills are offered in any diameter from 11.52mm to 50mm. Only 5 insert sizes cover entire range.

    Inserts are direct fit and require no adjustment to produce on size bores.

    The drills utilize screwed in guide pads

    Coated pads are also avaible.

    ADVANTAGES

    Versatility for use on lathe, machining centers and deep hole machines.

    High effieciency by specifically developed cutting edge geometry for diea chip formation

    Shortens downtime resulting from quick exchange of worn parts

    Easy to use, no sharpening, no length adjustment, easy inventory of wear parts.

    Lengthens tool life due to full coating, edge treatment and indexable designs

    Quick availability due to stocked wear parts and most common boy sizes.

    Triangle inserts have 3 cutting edges. Positive rake chip breakers and chip splitting geometries allow the use of feed rates 3 to 4 times greater than that of traditional gun drills. They are manufaturered from micrograin carbide and available in several PVD wear resistant coatings.

     Applications

    Medical instruments, automotive fuel systems, the glass industry, and many other applications can benefit by gundrilling very small holes with solid carbide flute drills. The strength afforded by the absence of a braze joint at the tip with tubular construction gun drills provides better penetration rates and tool life. However, gun drills of such small diameters require that the specific operating parameters are followed to ensure success. We are pleased to offer expert application engineering to make this happen.

    A few sizes for reference( Iscar inserts and pads, China pads, both available)
