Matework Countersink Drill Bit Set – M2 Cobalt HSS, 6-Piece, 1/4 Inch Quick-Change Hex Shank

Precision countersinking for metal and wood, made practical

The Matework Countersink Drill Bit Set brings together advanced materials and thoughtful design to help you achieve clean, controlled countersinks across a range of materials. Each bit is built around M2 cobalt high-speed steel, with a cobalt coating that enhances durability, corrosion resistance, and heat tolerance. The result is reliable performance through demanding tasks, without the guesswork that can slow you down on the job.

Performance you can count on

Key attributes are designed for real-world use in workshops and job sites. The five-flute geometry optimizes stability during cutting and promotes efficient debris evacuation, which helps maintain steady feeds and reduces heat buildup. A crisp, sharp edge paired with a robust coating supports smooth entry and consistent countersinking, even when you switch between metals and plywood.

• High-quality M2 cobalt HSS with a cobalt coating for durability, corrosion resistance, and heat tolerance.
• Five-flute design delivers stable cuts and efficient chip removal for faster drilling.
• Includes six sizes: 1/4", 3/8", 1/2", 5/8", 3/4" and a 5/16" special size to cover common countersink needs.
• Laser-engraved step sizes on the shanks for clear visibility and precise settings on the fly.
• 1/4" quick-change hex shank enables fast bit swaps and reduced downtime.

Versatility for metal and wood projects
