FAQ's: Annular Cutters

For thick metal, an annular cutter or step drill bit often gives faster, cleaner results.

TCT (tungsten carbide tipped) is better for hard materials like stainless steel and cast iron; HSS (high-speed steel) is more forgiving and cost-effective for mild steel.

Tungsten carbide is the primary material used to make solid carbide tools. “Solid carbide” usually means the whole cutting edge is carbide, while some tools just have carbide tips.

Hole saws are for wood, plastic, and light metal, while annular cutters are precision tools for metal, offering cleaner cuts and longer life in heavy-duty applications.

A drill bit removes all material inside the hole, while an annular cutter removes only a thin ring, leaving a solid slug in the center.

They cut large-diameter holes in metal efficiently, removing only the material at the hole’s perimeter, which reduces cutting time and effort.

Mostly, yes—they’re optimized for through holes, but with careful depth control, they can be used for blind holes.

For hole saws or circle cutters, attach them to the drill using the appropriate arbor/mandrel, ensuring it’s tightened securely before use.

They’re extremely precise compared to twist drills, producing burr-free holes with tight tolerances and clean edges.

With correct feed, speed, lubrication, and material matching, a quality cutter can last dozens to hundreds of holes before resharpening.

Use the correct arbor or adapter for your drill type. For annular cutters, you’ll typically use a Weldon shank adapter in a magnetic drill.

Very accurate—most produce holes within ±0.005" tolerance when used in a stable setup with proper feed and speed.

No. Annular cutters use a pilot pin that helps center the cut and eject the slug. A separate pilot hole is not required.

Not recommended. Annular cutters are designed for use in magnetic drill presses or rigid setups. A hand drill can’t provide the stability and torque needed for safe, accurate cutting.
