COMOWARE Cobalt Drill Bit Set 14Pcs M42 8% HSS with Case

Meet a drill bit set designed to tackle demanding materials with calm confidence. The COMOWARE Cobalt Drill Bit Set blends a tough M42 8% cobalt high-speed steel core with precise geometry to support reliable performance across metal, wood, and plastic projects. This kit is built for projects that demand both endurance and accuracy, offering a balanced mix of strength, precision, and organization.

Key features that matter in real work

• 8% cobalt HSS (M42) material aims for longer tool life and improved wear resistance compared to standard high-speed steels.
• 135° split point paired with a gold oxide finish helps start holes cleanly and reduces wandering, while improving chip clearance.
• Fully ground bits with round straight shanks promote stable operation and consistent cutting performance.
• Designed to cut through hardened metals and alloys, including stainless steel, cast iron, high-temp alloys, titanium alloys, hard plastics, and wood, with broad applicability for professional and DIY tasks.
• Vertical operation design distributes blade-tip stress evenly to help minimize tip damage during heavy drilling.

What you get and how it helps

• 14 pieces in a single jobber-length set: 1/16", 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 3/16", 7/32", 1/4", 5/16", 3/8", 1/2".
• Plastic indexed storage case for quick access and organized tool management, so you can locate the right size fast.

Real-world use scenarios include drilling pilot holes in stainless brackets, cutting through hard plastics, or creating precise holes in cast iron. The robust build supports repeated drilling sessions in workshop settings, while the sharp geometry aims to produce clean holes with less effort. The kit’s broader size range helps you cover small pilot holes up to large through-holes in a single set, reducing the need to swap bits mid-project.
