Expertly engineered for high-efficiency hole-starting and chamfering operations in modern automated manufacturing environments, the Guhring NC Spotting Drills HSS 90-Degree range is the definitive industrial choice for ensuring flawless drill alignment. Manufactured from premium high-speed steel (HSS), these tools feature a specialized un-coated bright finish that provides an ultra-sharp cutting edge to minimize torque loads and prevent work hardening on entry. The specialized ultra-short flute length and heavy web core deliver exceptional torsional rigidity, completely eliminating tool deflection or walking when initiating deep hole sequences on CNC machining centres or conventional drill presses. Ground to an exact 90° point angle, these heavy-duty steel spotting drills establish an absolute true location point while simultaneously cutting a clean entry chamfer for subsequent twist drills, eliminating an extra tool-change cycle. This versatile HSS spotting series is optimized to deliver exceptional tool life and reliable accuracy across tough structural materials, including structural steels, mild steel, AS/NZS 3678 250 and 350 grade plate, free-cutting steels, and unalloyed case-hardened plates.
