High-Performance Spotting for Precision Hole Starts

This 90° solid carbide spotting drill with AlTiN coating is engineered for accurate hole positioning and chamfering in high-performance machining environments. The 90-degree point angle is ideal for preparing holes prior to drilling or creating precise chamfers for flat-head fasteners. Manufactured from premium solid carbide, this tool delivers exceptional rigidity and dimensional stability. The AlTiN (Aluminum Titanium Nitride) coating provides enhanced heat resistance, improved wear protection, and extended tool life—making it well suited for higher-speed machining and tougher materials.
