⭐ Key Features
•1/2" Diameter for Large Holes: Ideal for creating bolt holes in heavy steel plates and structural members
•Superior Hardness & Durability: Manufactured from M35 cobalt HSS (5% cobalt), heat-treated to HRC 72 for long-lasting performance in hard metal applications
•Extreme Heat Resistant TiAlN Coating: Withstands temperatures up to 1000°C. Reduces friction and tip temperature, preventing burn-out when drilling thick steel plates or structural beams
•135° Split Point for Aggressive Drilling: Self-centering tip eliminates walking and requires less downforce, ideal for large-diameter holes in hardened materials
•Long Working Length: 4-1/2" flute length allows you to drill through 3" thick material in one pass, perfect for pipe flanges and heavy equipment
•The drill bits use a dual-layer design for security and durability. The outer clamshell is ultrasonically welded, making tampering evident and ensuring factory-fresh arrival. Inside, a custom storage box prevents metal-on-metal contact, protecting bit edges and coatings. The box also serves as a permanent organizer, keeping bits separated by size. This system guarantees product integrity at purchase and offers a reusable storage solution for the bits' lifetime
