High Speed Uncoated Carbide Step Drill Extra Long Life No Coating for Sharp Cutting CNC Use

Our High-Speed Uncoated Carbide Step Drill is engineered for precision and durability in demanding machining applications. Made from solid tungsten carbide (WC) without coatings, this step drill delivers exceptional sharpness, heat resistance, and extended tool life—ideal for high-speed CNC operations and manual use.

Key Features
  • Solid Tungsten Carbide Construction - Superior hardness (90-94 HRA) for wear resistance in hardened materials.
  • Uncoated Design - Ensures razor-sharp cutting edges, reducing friction and material buildup (ideal for non-ferrous metals).
  • High-Speed Performance - Optimized flute geometry for efficient chip evacuation at elevated RPMs.
  • Multi-Diameter Steps - Single bit replaces multiple drill sizes (e.g., 4-12mm range in one tool).
  • CNC & Handheld Compatible - Precision-ground for stability in CNC machines or handheld drills.
  • Extra Long Tool Life - Carbide's heat resistance minimizes wear, even in continuous operation.
Advantages

No Coating = Sharper Cuts - Avoids edge rounding common with TiN/TiAlN coatings, critical for fine finishes.

Better for Sticky Materials - Prevents aluminum/copper from adhering to flutes.

Cost-Effective - Uncoated carbide lasts longer than HSS while being cheaper than coated carbide.

Applications
  • Metalworking: Drilling stainless steel, aluminum, brass, and thin sheet metal.
  • Electronics: Precise holes in PCBs, fiberglass, and ceramic substrates.
  • Automotive/Aerospace: Lightweight alloy machining and deburring.
  • DIY & Maintenance: Versatile use for HVAC, plumbing, and repairs.
