Countersinks – Hand Deburring Tools

Noga countersinks are hand deburring 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 patented 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 patented 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.

Noga Countersinks are specialized hand deburring tools designed to provide clean and precise chamfers on drilled holes and edges. These tools efficiently remove rough ridges and create smooth, professional finishes on both internal and external surfaces. Noga countersinks are ideal for tasks like chamfering holes and deburring edges, ensuring a polished look.

A key feature of  countersinks is the patented Rotodrive Cranked Countersinks system, which allows for continuous rotation, making deep hole chamfering easier and more accurate. The ergonomic cranked handle provides enhanced control and comfort during use.

For external deburring, Noga countersinks effectively remove burrs from the outside of tubes and rods, ensuring smooth edges on cylindrical materials. Additionally,  countersinks offer reversible countersinks that feature a swiveling blade, allowing for inside deburring and external surface chamfering with ease. These versatile tools guarantee clean finishes on both flat and curved surfaces.

Constructed with high-speed steel blades, countersinks and Noga tools offer durability and sharp cutting performance. Whether working with metal or plastic, these tools ensure long-lasting results and improved efficiency in achieving smooth chamfers and burr-free edges.

FAQs

 What are countersinks used for?

Ans: Countersinks are specialized deburring tools designed to remove rough edges from drilled holes. They create a smooth, chamfered edge that improves both the appearance and functionality of parts, especially by allowing flat-head screws to sit flush with the surface.

 How does the Rotodrive system improve the chamfering process?

Ans: The Rotodrive system allows for continuous rotation, making it easier to chamfer deep or difficult-to-reach holes. This feature provides better control, efficiency, and precision, which is ideal for both light and heavy-duty deburring tasks.

 Can countersinks be used for external deburring as well?

Ans: Yes, countersinks are also highly effective for external deburring. They can be used to chamfer the edges of tubes, rods, and other cylindrical surfaces, providing a smooth finish on both internal and external surfaces of materials.

 What materials can countersinks handle?

Ans: Countersinks are versatile and can handle a wide range of materials, including metals, plastics, and composites. The high-quality blades are designed for durability and performance, allowing you to achieve a smooth, professional finish on different materials.

 Why should I choose a countersink over other deburring tools?

Ans: Countersinks offer a precise and controlled method for chamfering both internal and external edges. Their design allows for smooth, consistent results even on curved or cross holes, making them an essential tool for creating clean, functional edges. With their durability and efficiency, countersinks are a preferred choice over other deburring methods.
