What is better than a hole saw?
For thick metal, an annular cutter or step drill bit often gives faster, cleaner results.
Which is better, TCT or HSS annular cutter?
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.
What is the difference between solid carbide and tungsten carbide?
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.
What is the difference between a hole saw and an annular cutter?
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.
What is the difference between a drill and an annular cutter?
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.
What are annular cutter bits used for?
They cut large-diameter holes in metal efficiently, removing only the material at the hole’s perimeter, which reduces cutting time and effort.
Is an annular cutter only made for through holes?
Mostly, yes—they’re optimized for through holes, but with careful depth control, they can be used for blind holes.
How to put a circle cutter on a drill?
For hole saws or circle cutters, attach them to the drill using the appropriate arbor/mandrel, ensuring it’s tightened securely before use.
How precise are annular cutters?
They’re extremely precise compared to twist drills, producing burr-free holes with tight tolerances and clean edges.
How long do annular cutters last?
With correct feed, speed, lubrication, and material matching, a quality cutter can last dozens to hundreds of holes before resharpening.
