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 DesignUnlike 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:Heavy-Duty ConstructionHigh-Speed Steel (HSS) Blades: Hardened to 62-64 HRC for exceptional wear resistance90-Degree Cutting Angle: Standard geometry for most external chamfering applicationsSingle-Flute Design: Provides smooth, chatter-free cutting on external surfacesRobust Build Quality: Engineered for demanding industrial environmentsVersatile Size RangeAvailable in multiple blade configurations to handle various external diameters:C12 Model: For shafts 3-12mm diameterC20 Model: For shafts 3-20mm diameter (most popular)C30 Model: For larger shafts 10-30mm diameterEX28 External RotoDrive: Specialized for 8-28mm external chamferingEX34 External RotoDrive: For heavy-duty 10-34mm applicationsErgonomic Handle SystemNG-3 Heavy-Duty Handle: Wide-body design with superior grip40mm Displacement: Provides leverage for removing heavy burrsLightweight Construction: Only 28 grams (blade) for reduced operator fatigueHeat-Treated Components: Ensures long-term durability under harsh conditionsQuick Blade ReplacementModular Blade System: Interchangeable blades for different sizes and materialsCompatible Holders: Works with NogaGrip-1 and RotoDrive holdersTool-Free Changes: Internal threading allows fast blade swapsCost-Effective Maintenance: Replace only worn blades, not entire toolTechnical Specifications:Blade Characteristics:Material: High-Speed Steel (HSS)Hardness: 62-64 Rockwell CAngle: 90 degrees (standard)Coating Options: Standard HSS or TiN-coated for extended lifeWeight: 28 grams (typical blade)Packaging: Individual or 10-piece packs availableHandle Specifications:Type: NG-3 Heavy-Duty with cranked designMaterial: Reinforced polyacetal plasticDisplacement: 40mm for heavy-duty applicationsCompatibility: All C-Type countersink bladesHeat Treatment: Wear-resistant surface treatmentApplications & Industries:Ideal For External Chamfering:Hydraulic & Pneumatic Shafts: Smooth chamfers prevent seal damage during assemblyDrive Shafts & Axles: Professional finishing for automotive componentsThreaded Rods & Bolts: Chamfer cut ends for easier nut startingDowel Pins: Remove sharp edges for safe handling and press-fittingTube Ends: Prepare pipe ends for welding or fitting assemblyBar Stock: Finish cut ends of round and hex bar stockCNC Machined Parts: Final deburring of external diametersRepair & Maintenance: Restore damaged thread starts on boltsMaterial Compatibility:Ferrous Metals: Steel, stainless steel, tool steel, cast ironNon-Ferrous Metals: Aluminum, brass, copper, bronze, titaniumPlastics: Nylon, acetal, polycarbonate, PVC, PEEKComposites: Carbon fiber, fiberglass reinforced materialsWood & Non-Metals: Hardwood dowels, composite rodsWhy 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 costsSignificantly faster than manual filing or grindingNo power consumption or air supply requiredMinimal training required for operatorsDurable construction provides years of reliable serviceHow It Works:Select Appropriate Blade: Choose C12, C20, or C30 based on your shaft diameterMount Blade: Attach countersink blade to NG-3 handle via threaded connectionPosition Tool: Place external countersink around shaft end or edgeRotate Continuously: Use cranked handle to rotate tool around workpieceApply Light Pressure: Let the sharp HSS blade do the cutting workInspect Results: Achieve smooth, uniform chamfer in secondsNoga Quality & Heritage:Noga Engineering has been the global leader in precision hand deburring tools since 1980. Their patented innovations have set industry standards for quality, ergonomics, and performance. The C-Type Heavy Duty Countersink represents decades of engineering excellence, delivering professional-grade tools trusted by manufacturers worldwide.Quality Certifications:ISO 9001:2015 certified manufacturingPrecision-ground cutting edgesRigorous quality control testingBacked by manufacturer warrantyPackage Includes:1x Noga NG-3 Heavy-Duty Handle (cranked design)1x C-Type Countersink Blade (specify size: C12, C20, or C30)1x RotoDrive Holder (compatible holder)User Manual with technical specificationsAvailable Configurations:Complete Sets: Handle + holder + blade (NG3100, NG3400 series)Replacement Blades: Individual blades (BC1211, BC2011, BC3011)Blade Packs: 10-piece quantity for production environmentsTiN Coated Blades: Extended life for abrasive materialsUpgrade your external deburring operations with the Noga C-Type Heavy Duty Countersink and experience professional-grade shaft chamfering that manual filing and grinding simply cannot match.

RotoDrive Cranked Countersinks which allows the user to chamfer holes, deep holes and continuous rotation for fast and accurate chamfering.   If a hole is drilled into a work piece, usually a rough edge will appear around the top of the hole. Noga countersinks can remove these rough ridges and put a chamfer between the hole and the surface into which the hole was drilled. Noga Countersinks can also create a deeper recess into a hole, in order to prevent a flat head screw from projecting over the surrounding surface. Noga Countersinks are hand-operated tools normally used for producing a small chamfer, but may also be gripped in a drill press to create deeper recesses. Noga Countersinks consist of three parts: A blade of high speed steel, a holder, and a handle. The Noga Countersinks are used like a screw-driver, pressed onto the hole, and rotated clockwise. However, another method to perform the rotation is offered with our Noga Countersinks Rotodrive system. In this case the blade-holder has the form of a crank, which enables the user to perform continuous rotations. With the Rotodrive system, Noga Countersinks also offers External Countersinks, with which rough edges can be chamfered on the outside of tubes and round bars. For external and internal light chamfering, Noga makes Reversible Countersinks. If a cross hole was drilled into a tube, this tool can be inserted into the hole, then a blade can swivel out to deburr the inside break-through, by rotating the tool clockwise and anticlockwise. Contrary to other Noga countersinks, this tool can create good chamfers also on curved surfaces, because its cutting edges will follow exactly the contour of the hole. As well as on the inside of cross holes, they can also chamfer the outside burrs.   APPLICATION Holes External Shaft
