Champion CSK-SET-5 Countersink Set — Zero Flute HSS Countersinks for Professional Deburring & Finishing
The Champion CSK-SET-5 Countersink Set is a comprehensive professional kit featuring Champion’s zero flute countersinks, engineered for smooth, chatter-free deburring and countersinking across a wide range of hole sizes. Designed for metalworking, fabrication, maintenance, and assembly applications, this set delivers clean chamfers and precise flat-head fastener seating with consistent results.
Each countersink in the CSK-SET-5 is manufactured from high-speed steel (HSS) and utilizes a zero flute cutting geometry that maintains continuous cutting contact with the workpiece. This design eliminates vibration, reduces grabbing, and produces superior surface finishes—especially on thin materials and softer metals where traditional multi-flute countersinks struggle.
The CSK-SET-5 offers expanded size coverage compared to smaller sets, making it an ideal solution for shops and technicians who need versatility and reliability when deburring drilled holes, breaking sharp edges, and preparing holes for flat-head screws.
What’s Included in the CSK-SET-5
- Multiple zero flute countersinks covering a broader range of countersink diameters
- High-speed steel construction for durability and long tool life
- Standard round shanks for use in hand drills and drill presses
- Protective storage case for organization and portability
