VEVOR Annular Cutter Set, 5 pcs Weldon Shank Mag Drill Bits Kit, 25.4 mm Cutting Depth, 15.87 mm Cutting Diameter, HSS, 3 Drill Bits with 2 Pilot Pins and 3 Plastic Cases, for Magnetic Drills, Steel

Weldon Shank Drill Bits That Fit Most Magnetic Drills

The majority of magnetic drills are designed to accept a standard 3/4" Weldon shank, which is what these Weldon shank drill bits use. These bits fit right in if your mag drill has a Weldon clamp, which is what most do. They are widely compatible because of that common shank. They fit the tool you already have, so you don't need a special fitting or adapter.

It is compatible with all brands. These cutters are compatible with nearly every major brand of magnetic drill on the market because the Weldon shank is a common standard. Switching cutters takes only a few seconds, and they're easy to install and remove during regular tool changes. That simple, universal fit reduces downtime between holes. It eliminates the need to worry about whether a new cutter will fit in your machine for anyone who regularly uses a mag drill: wide fit, standard shank, and quick changes are all available.

M2AL HSS Build for Wear Resistance and Long Life

The M2AL high-speed steel used to make the cutters was selected for its ability to withstand severe cutting. Because of M2AL HSS's high wear resistance, the cutting edges don't dull after a few holes and remain sharp even after repeated use. Additionally, it can withstand high temperatures, which matters because drilling steel generates heat at the edge. A cutter that deteriorates or softens quickly when exposed to heat needs frequent replacement.

A longer service life is directly correlated with resistance to heat and wear. In the long run, quality steel is worth it because you get more holes per cutter and more jobs out of the set before you need to replace anything. Cheap cutters cost less upfront, but they wear out faster and end up costing more. These are designed to continue cutting cleanly through numerous steel jobs. The durability of the M2AL HSS build is what makes working cutters worth their money.

5/8 in Diameter and 1 in Cutting Depth for Steel

Each cutter drills a 5/8-inch (15.87 mm) hole to a full 1-inch (25.4 mm) cutting depth. That bit size and depth cover many typical metalworking holes. These cut cleanly through thick material, such as structural steel plate, in a single pass rather than stopping short because of the 1-inch depth. Without a second operation, you obtain a full-depth hole with the precise diameter you require.

You can get precise, repeatable holes thanks to the cutters' uniform 5/8" diameter. A cutter that maintains its size matters when drilling a run of holes that must all match. Hole after hole, these produce the same spotless 5/8" bore. The result is accurate, full-depth holes in steel and other metals, thanks to M2AL steel, which maintains a sharp edge. Accuracy and depth are crucial for structural work where the hole size must be precise.

Annular Cutting Design for Smooth Chip Flow

In contrast to a typical twist drill, these are annular cutters. An annular cutter cuts only the ring around the edge, leaving a solid slug in the center, rather than chewing up the entire hole into chips. Cutting is quicker and requires less force because there is much less material to remove. Mag drills use this design because it effectively drills a clean hole in thick steel.

Larger chip slots maintain smooth cutting. Instead of allowing chips to pack up and jam the cut, those wider slots move them out of the way as the cutter operates. The cutter enters the material cleanly rather than skating or grabbing because its flat, pointed blade geometry helps it bite in steadily at first. These cutters bore through steel with less effort and mess thanks to their annular design, large chip slots that clear debris, and blade geometry that facilitates entry.

5-Piece Set with Pilot Pins and Storage Cases

The five-piece Weldon shank drill bits set includes three annular cutters, two pilot pins, and three plastic storage cases. The 1/4" by 3" pilot pins perform a crucial function. To start precisely, they center the cutter on the mark. When the hole is finished, they eject the remaining slug from the cutter's center. Since pilot pins are the most likely to be lost, having two pins means you have a spare.

The three storage cases keep everything safe and organized for transport. Each cutter has its own case, so loose cutters don't rattle around a toolbox and chip their edges. This makes it easy to grab the right cutter and go, while also protecting the cutting edges. Keeping the cutters, pins, and cases together as a set ensures you arrive with everything you need, with nothing missing for maintenance, replacement, and routine metal drilling.

Weldon Shank Drill Bits for Structural Metalwork

These Weldon shank drill bits aren't designed for light-duty hobby drilling but for real structural metalwork. They cut various metals you'll encounter on a job, including structural steel, stainless steel, aluminum, cast iron, and copper. These handle the common metals that a fabricator or field crew encounters, so you don't need to switch to different bits for different metals due to their broad material capability.

That toughness matches the applications. These cutters are designed for heavy jobs that require precise, full-depth, clean holes, such as drilling in steel structures, bridge construction, rail projects, shipbuilding, and general metal fabrication. They enable you to precisely drill holes in structural steel wherever the work is located when used in conjunction with an on-site magnetic drill. This set delivers the durability and cutting performance that serious metalworking demands: for large projects, structural steel, and properly executed holes.
