Expertly engineered for high-precision hole-starting and alignment operations in demanding manufacturing environments, the Guhring Plain Type Machine Centre Drill range is the definitive industrial choice for establishing rigid workpiece seating. Manufactured from premium cobalt-alloyed high-speed steel (HSS-E) to strict Type A parameters, these double-ended tools are precision-ground to produce a clean, standard 60° countersink combined with a precise pilot entry point. This dual-action geometry guarantees perfect concentricity and completely eliminates tool wandering when initiating deep-hole drilling paths on CNC machining centres or setting up supporting work between conventional lathe centres. The robust web thickness and specialized flute structure efficiently clear compact swarf to maximize tool life and prevent entry breakage. This plain-type centre drilling series is optimized to deliver exceptional dimensional compliance across structural steels, mild steel, AS/NZS 3678 250 and 350 grade plate, free-cutting steels, and unalloyed case-hardened plates.
