3Pcs 3/8 Inch Drill Bit - Industrial M35 Cobalt Titanium Aluminum Nitrite, 135° Split Point - 3/8" Diameter & 5" Total Length with 3-5/8" Working Length - for Heavy-Duty Steel, Stainless & Alloy

3Pcs 3/8 Inch Drill Bit - Industrial M35 Cobalt Titanium Aluminum Nitrite, 135° Split Point - 3/8" Diameter & 5" Total Length with 3-5/8" Working Length - for Heavy-Duty Steel, Stainless & Alloy

• 3/8" Diameter for Heavy-Duty Applications: Suitable for large holes in structural steel, beams, and heavy plates
• Superior Hardness & Durability: Made from M35 cobalt HSS containing 5% cobalt, heat-treated to HRC 72 for extreme durability in hard metal applications
• High-Performance TiAlN Coating: Withstands temperatures up to 1000°C, protecting the bit from burning and ensuring consistent performance in stainless steel and structural steel
• 135° Split Point for Aggressive Starts: Self-centering tip reduces walking and dramatically lowers drilling force, ideal for thick plates and beams
• Ideal for Construction and Fabrication: Perfect for steelworkers, ironworkers, and heavy equipment maintenance
• 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
