Expertly engineered for high-precision hole-starting and chamfering operations in high-speed automated manufacturing environments, the Guhring NC Spotting Drills HSS TiN Coated 90-Degree range is the definitive industrial choice for ensuring flawless drill alignment. Manufactured from premium high-speed steel (HSS) and enhanced with an advanced Titanium Nitride (TiN) coating, these rigid tools deliver exceptional surface hardness and superior thermal resistance to eliminate rapid edge breakdown during continuous production paths. The specialized ultra-short flute length and thick web core provide maximum torsional rigidity, completely eliminating tool deflection or walking when initiating deep hole sequences on CNC machining centres. Ground to an exact 90° point angle, these spotting drills create an absolute true location point while simultaneously cutting a clean entry chamfer for subsequent twist drills. This heavy-duty 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.
