5 32 Inch Cobalt Drill Bit Set (5/32 Inch)

Key Features

• 5/32" Diameter for Common Applications: Great for general metal drilling and fasteners
• Superior Hardness & Durability: Manufactured from M35 cobalt HSS containing 5% cobalt, heat-treated to HRC 72 for maximum durability and long tool life
• Heat-Shield TiAlN Coating: Reduces friction and prevents tip burning, allowing faster drilling in soft metals without clogging the flutes
• 135° Split Point for Easy Starts: Self-centering tip eliminates walking on smooth surfaces, giving you clean, accurate holes every time
• Compact Flute for Control: 2" working length reduces bit flex, ideal for hand drilling in thin steel, aluminum sheets, and copper pipe
• 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
