Noga C-Type Heavy Duty Countersink Blades & Handles - Professional External Chamfering Solution
The Noga C-Type Heavy Duty Countersink represents a breakthrough in external deburring technology, featuring a patented design specifically engineered for chamfering external shafts, rods, tubes, and cylindrical surfaces. This innovative tool system is essential for professionals in mechanical assembly, automotive manufacturing, hydraulic systems, aerospace fabrication, and precision machining operations.
Revolutionary External Countersink Design
Unlike traditional countersinks designed for internal hole deburring, the Noga C-Type features a unique external configuration that wraps around the outside diameter of shafts and rods. This patented geometry enables you to create perfect chamfers on external edges where conventional tools simply cannot reach.
Patented RotoDrive Technology:
The cranked handle design with integrated RotoDrive mechanism allows continuous 360-degree rotation around external workpieces. This continuous rotation capability delivers exceptionally fast and accurate chamfering compared to intermittent manual methods, reducing production time by up to 60% on repetitive external chamfering operations.
Key Features:

Why Choose Noga C-Type External Countersink?
Unmatched External Deburring Capability:
The C-Type is the only hand tool specifically designed for external shaft chamfering with continuous rotation capability. Traditional files, grinders, or internal countersinks cannot match its speed, precision, and consistency on external diameters.
Production Efficiency:
The continuous rotation feature dramatically increases throughput in production environments. What once required 2-3 minutes of filing per shaft now takes just 15-20 seconds with the C-Type countersink.
Operator Safety:
Unlike angle grinders or files that generate heat, sparks, and sharp metal fragments, the C-Type operates cleanly and safely. The controlled cutting action produces small chips rather than dangerous flying debris.
Consistent Quality:
Every chamfer is uniform and repeatable. The 90-degree blade angle ensures compliance with engineering drawings and assembly requirements, eliminating rework from inconsistent manual deburring.
Cost Effectiveness:
Replaceable blade system reduces long-term operating costs
Significantly faster than manual filing or grinding
No power consumption or air supply required
Minimal training required for operators
Durable construction provides years of reliable service
How It Works:
Select Appropriate Blade: Choose C12, C20, or C30 based on your shaft diameter
Mount Blade: Attach countersink blade to NG-3 handle via threaded connection
Position Tool: Place external countersink around shaft end or edge
Rotate Continuously: Use cranked handle to rotate tool around workpiece
Apply Light Pressure: Let the sharp HSS blade do the cutting work
Inspect Results: Achieve smooth, uniform chamfer in seconds
