Description
3-7/16″ Diameter – Annular Cutter – High Speed Steel – 4″ Depth of Cut | The 9100SE series broach annular cutters are expertly crafted for the swift and efficient production of large diameter holes, providing significant energy savings and faster penetration with less thrust than traditional solid drills. These innovative cutters remove only the periphery of the hole and discharge a slug upon completion, drastically reducing drilling time. For instance, while a solid drill might take 3 minutes and 45 seconds to drill a 1-1/4” hole in a 3/4” plate, the 9100SE series accomplishes the same task in just 35 seconds. Prepackaged with corresponding pins, these cutters accommodate sizes ranging from 7/16″ to 1-1/2″, making them an ideal choice for efficient metalworking.Additional information

FAQ's: Annular Cutters
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.
How do you attach a hole cutter to a drill?
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.
How accurate is an annular cutter?
Very accurate—most produce holes within ±0.005" tolerance when used in a stable setup with proper feed and speed.
Do annular cutters need a pilot hole?
No. Annular cutters use a pilot pin that helps center the cut and eject the slug. A separate pilot hole is not required.
Can you use an annular cutter in a hand drill?
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.
