This detailed product description refers to the premium quality spot weld drill from Wieländer+Schill, specifically designed for efficient and precise machining of steel materials. The high-quality HSS (High-Speed Steel) base material and the special TiN-GOLD coating guarantee a long service life and excellent cutting performance.
This drill is the ideal choice for body repair work where the removal of spot welds requires precision and reliability. The drill's design is optimized for fast and clean material removal, minimizing the risk of damage to surrounding material.
Key advantages:
Long Lifespan: The HSS (High-Speed Steel) base material provides exceptional strength and wear resistance.
Superior Surface Treatment: A TiN-GOLD (Titanium Nitride Gold) coating significantly reduces friction, increases heat resistance, and improves chip evacuation, resulting in smoother drilling and longer tool life.
Precise Spot Weld Removal: Features a geometry optimized specifically for drilling spot welds.
Optimal Rotational Speed: The recommended speed range ensures optimal tool performance when machining steel.

A TiN-GOLD Coating not only represents an aesthetic value; it is an extremely hard ceramic layer applied to the surface of the drill bit. This coating ensures that the drill bit resists the high temperatures generated during high-speed drilling, especially when machining hard materials like steel. The gold color refers to the high-quality coating process, which guarantees the tool's consistent performance.
A HSS (High-Speed Steel) material choice ensures the drill bit remains flexible while maintaining its sharpness. The two-flute (2 Flutes) design is ideal for chip evacuation at the drilling depth, preventing tool clogging and overheating.
Area of application: This drill bit is specifically developed for the fast and clean drilling through spot welds used in the automotive and metal processing industries, enabling the damage-free removal of weld points during body panel replacement or repair. The standard 8 mm diameter fits most factory spot welds.
The recommended speed of 800-1000 rpm ensures the proper cutting speed without causing the drill bit to overheat or the tool edge to wear prematurely. The precise 8.0 mm diameter guarantees that the drilled hole perfectly fits standard spot weld dimensions.
This product belongs to the Wieländer+Schill category of „Separating Tools”, found within the „Drilling Tools” section, confirming its professional quality and specialization.
