Drill Bits

The Dormer A777 drill bits are designed for both professional and industrial use, offering reliable performance in high-stress environments. The 135° split point design reduces walking and ensures precise drilling, while the HSS-E cobalt construction extends tool life and maintains sharpness longer, even at high temperatures. Constructed from high-speed steel with 8% cobalt, these drill bits offer exceptional hardness, heat resistance, and wear resistance, making them ideal for demanding applications. Features & Benefits • High speed cobalt steel • Standard spiral flute design • DIN338 • Bronze finish • NAS907J • Right hand rotation/cutting • 135° point …

The MAK4 is a premium SDS Max drill bit with a dynamic 4 cutter head. It has a symmetrical head geometry with centering tip which helps to limit the effects of rebar collision, with shortened spiral windings and conical shaped dust tracks for extra fast material removal. The MAK4 significantly raises the performance parameters of drilling speed and life expenctancy, considerably reducing the cost per hole. Ideal for concrete, stone, masonry, engineering brick, fixings & anchors. Features & Benefits • Premium SDS Max drill bit with a dynamic 4-cutter head • Symmetrical head geometry with centering tip • Shortened spiral windings and conical shaped dust tracks for extra fast material …
