Introduction to Annular Cutter
Annular cutters, also called mag drill bits, core cutters, rota-broach cutters, or broach cutters, are metalworking tools used in creating holes. It's often used with a magnetic drill press and is considered a more efficient alternative to standard twist drills or hole saws due to its unique cutting mechanism that only removes material around the periphery of the hole.

Functions of Annular Cutter
Efficiency
Because an annular cutter only cuts the outline of a hole, it can cut almost 4 times faster than traditional drill bits like twist drills or hole saws. In addition, you can create a hole in one shot with a mag drill bit, with no pre-drilling and step-drilling required.
Power saving
Unlike hole saws, mag drill bits require less power to operate due to their design. Instead of drilling through the whole workpiece, the cutters only focus on the outline, thus requiring less energy during operation.
Longer service life
Several cutting edges cut the workpiece simultaneously, so annular cutters are less likely to wear quickly. In addition, HSS and tungsten carbide are extremely durable wear-resistant materials, ensuring the longer service life of mag drill bits.
Burr-free
Due to the design of the teeth, annular cutters create fewer chips and can evacuate the chips during operation, leaving burr-free holes in the workpiece.
Accuracy
Mag drill bits can create accurate and clean holes by using a pilot pin. It is of great importance to drill holes accurately in applications like pipping.
Fabrication and assembly of steel structures
In industries such as construction, automotive, and aerospace, annular cutters are employed to create precise holes for bolting, riveting, and fastening components together. The ability to produce accurately sized holes is crucial for ensuring the structural integrity and safety of any assembly.
Plumbing and HVAC Installation
When installing pipes or ductwork, professionals need to drill precise holes through walls, floors, and ceilings. Annular cutters excel in these scenarios by offering the capability to cut through steel, aluminum, and other metals with ease. Their efficiency allows plumbers and HVAC technicians to complete installations quickly while maintaining high standards of accuracy.
Machinery and equipment manufacturing
In production environments, where components require precise fittings, the use of annular cutters can significantly enhance workflow and efficiency. By providing clean cuts, these tools help reduce the risk of misalignments during assembly, which can lead to costly rework and delays. The reliability and performance of annular cutters make them ideal for high-volume production settings.
Metalworking Repair and Maintenance
When machinery breaks down or components wear out, precise hole drilling is often required to replace parts or perform upgrades. Annular cutters can facilitate this process by allowing maintenance professionals to make quick and accurate modifications, ensuring that machinery can return to operation with minimal downtime.
Woodworking and construction applications
Annular cutters can be used to create holes for dowels, screws, and other fasteners in various woodworking projects. The clean and precise cuts they provide are essential for achieving strong joints and connections, enhancing the overall quality of the finished product. This adaptability makes annular cutters valuable tools for both professional woodworkers and DIY enthusiasts alike.
The annular cutter creates the hole in a 3-step process:
The pilot pin accurately centers the cutter over the area to be drilled.
During drilling, the pilot pin retracts and allows the internal lubrication to reach the cutting teeth.
When the hole is complete, the slug is automatically ejected from the cutter, leaving an accurate, finished hole.
