VEVOR Annular Cutter Set, 4 pcs Weldon Shank Mag Drill Bits Kit, 1″ Cutting Depth, 1″ Cutting Diameter, HSS, 2 Drill Bits with 2 Pilot Pins and Plastic Cases, for Magnetic Drills, Steel, Aluminum

M2AL High-Speed Steel Construction for Extended Tool Life

This annular cutter with Weldon shank is made of M2AL high-speed steel, known for its high wear resistance and dependable performance in high-temperature drilling applications. Durability means the cutting blades stay sharp through repeated use on both steel and aluminum, reducing the number of tools that need to be replaced on active job sites. The M2AL composition is designed to withstand the heat generated during metal cutting for extended periods without softening or altering its edge geometry.

In addition to surface hardness, the material delivers consistent performance across a range of metal thicknesses and types. Each cutter in this set retains its shape during extended drilling, ensuring reliable results from the first to the final hole. With this level of material quality, projects can proceed without unnecessary disruptions, especially in workshops and field activities where tool reliability directly affects productivity.

4-Piece Cutter with Weldon Shank Kit for Complete Drilling Readiness

This kit is a full 4-piece set that includes two cutters with Weldon shanks, each with a cutting diameter of 1” and a cutting depth of 1”, and two 1/4” x 3” pilot pins for precise hole positioning. Everything comes in designated plastic storage boxes, so it can easily be taken between job sites or stored in a tool cabinet without loose pieces rolling around. A combination of cutters and pilot pins is included in a single kit, so you can start drilling right away without sourcing equipment individually.

The pilot pins that come with it help hold the cutter with Weldon shank in place during the first plunge, producing clean, well-placed holes. Each case is designed to keep the parts firmly in place, shielding the cutting edges from harm during shipping. This Weldon shank cutter kit is ideal for maintenance crews and fabricators who require a grab-and-go drilling option for everyday metalwork.

1″ Cutting Depth and 1″ Diameter for Precise Metal Removal

This cutter with weldon shank has a depth of cut of 1″ (25.4 mm) and a cutting diameter of 1″ (25.4 mm), providing a dependable size for routine structural and sheet metal work. The annular design cuts a ring of material rather than the entire slug, requiring less power from your magnetic drill and producing less waste with each cut. This method also results in lower cutting forces, which decrease the stress on the workpiece and the tool.

The entire profile remains small enough to work in tight or overhead positions, with a total blade length of 2.46 inches, including the shank. The flat, pointed blade design allows for a smooth cutting entry and helps prevent the cutter from walking on the surface during startup. The dimensions of these Weldon shank cutters make them suitable for common applications such as drilling bolt holes, conduit openings, and access points in metal constructions.

3/4″ Weldon Shank for Quick Installation on Magnetic Drills

All cutters use a 3/4″ Weldon shank. This is the most common shank type for magnetic drills from the major manufacturers. Compatibility means you can mount and dismount the cutters with standard Weldon clamps, eliminating the need for adapters or specialized tools for the transition. Fast tool changes are particularly useful for production tasks or multi-hole setups where cutter sizes change frequently.

The Weldon shank also offers a solid, non-slip fit in the drill arbor, preventing the cutter from spinning loose during heavy cuts. This solid connection means cleaner hole finishes and more precise cutting, especially when working with thicker material. The shank style makes for quick setup and smooth operation, whether using a portable mag drill on structural steel or a bench-mounted machine in the shop.

Annular Cutting Design with Enlarged Chip Slots for Smooth Operation

These bits use an annular cutting geometry, so they cut metal in a ring pattern rather than grinding through the entire diameter of the hole, leaving a clean slug. This approach uses far less energy from the drill motor than twist drilling, making it easier on equipment and the operator during repetitive work. The outcome is higher hole productivity with significantly less vibration and noise at the work surface.

The body of the cutter has enlarged chip slots. These are important for diverting metal shavings from the cutting area. These grooves minimize chip build-up around the teeth, helping to maintain a consistent feed rate and reducing the possibility of the cutter sticking in the middle of the hole. This combination of an annular shape and efficient chip clearance keeps the drilling process clean throughout, even in dense materials such as structural steel.

Versatile Cutter with Weldon Shank for Multi-Material Metalworking

This cutter with weldon shank is designed for a variety of metalworking jobs, from cutting structural steel beams and plates to drilling clean holes in aluminum panels and components. With the M2AL HSS material and the annular cutting design, consistent results are obtained across these diverse metals without any need to adjust the procedure or tooling setup. For fabrication shops, maintenance teams, and on-site contractors, a single package that covers various material types is helpful.

It is widely used in steel frames to cut bolt holes, in drill openings for conduit and piping, and to prepare connection points in aluminum fabrication projects. For most of the ordinary drilling activities encountered in construction, manufacturing, and repair operations, a cutting depth of 1” and a diameter of 1” are appropriate. If you regularly operate mag drills on mixed materials, this set is a practical, ready-to-use solution for the workplace or the field.
