Thürmer Tools PRO TCT (carbide tipped) Bor 4.0X43/75 HSS, ground DIN 338

Thürmer Tools HSS Twist Drill with TCT tip (carbide-tipped), ground DIN 338, is a professional precision tool developed for efficient and accurate drilling—even in demanding materials. TCT stands for Tungsten Carbide Tipped, meaning the drill combines a robust HSS (high-speed steel) body with a brazed tungsten carbide cutting tip. This construction delivers very high wear resistance, improved heat resistance, longer tool life, and stable cutting performance in repetitive drilling operations. The precision-ground finish to DIN 338 ensures smooth chip evacuation and clean, dimensionally accurate holes with excellent guidance. Suitable for professional use as well as quality-focused DIY work, and typically used for drilling alloy steel, non-alloy steel, stainless steel, cast iron, spheroidal cast iron, aluminium, copper, titanium alloys, and plastics.
