Solid Carbide Drills

HSS (High-Speed Steel) drills are versatile and commonly used for drilling a variety of materials, such as steel, wood, and plastics. They are more affordable compared to carbide drills and are suitable for less demanding applications. On the other hand, carbide drills are made of a tougher material that can withstand higher temperatures, making them ideal for drilling hard materials such as stainless steel, titanium, and other alloys. Carbide drills offer superior performance and longer tool life, but they come at a higher cost.

Yes, carbide drills are capable of drilling through hardened steel. Due to their hardness and heat resistance, carbide drills can effectively cut through tough materials like hardened steel without losing their edge. However, it’s essential to ensure proper drilling parameters (e.g., speed, feed rate, and coolant) to prevent excessive wear or breakage.

While carbide tools are known for their durability and performance, they come with some drawbacks. The main disadvantage is their brittleness — carbide tools are more prone to chipping or breaking if not handled correctly or if they encounter shock loads. They also tend to be more expensive than their HSS counterparts. Furthermore, carbide tools require precise machining conditions and careful handling during installation and operation.
