Can you use an annular cutter in a hand drill?
Hougen makes many different annular cutters even ones for sheet metal. Below are two styles of annular cutters for use in hand-held drills and drill presses. They offer many of the same advantages as the mag drill annular cutters such as speed, quality of hole and longer tool life.
What is an annular cutter bit used for?
An annular cutter is a specialized bit for drilling through steel. Like a hole saw for wood, an annular cutter only cuts the outside edge of a hole. It produces accurate burr-free holes to close tolerances without pre-drilling or step drilling.
Which is better TCT or HSS annular cutter?
Although seemingly more costly than the HSS cutter initially, TCT cutters are more robust and can cut multiple times more holes, operate at higher speeds and in some cases can cut through even the toughest of materials, including stainless steel and cast iron.
How many holes can an annular cutter cut?
They have up to 12 cutting edges to cut around the hole, leaving only a center slug which pops out. Quality burr-free holes can be cut in a single pass, 3-5 times faster than conventional twist drills. They can also cut multiple (overlap) hole configurations as well as curved surfaces and interrupted cuts.
Do annular cutters need a pilot hole?
The annular cutter creates the hole in a 3-step process: The pilot pin accurately centers the cutter over the area to be drilled. 2. During drilling, the pilot pin retracts and allows the internal lubrication to reach the cutting teeth.
What is the difference between twist drill and annular cutter?
Twist Drill: Twist drills are efficient for smaller holes, but they may require more force and time when drilling larger holes due to their design. Annular Cutter: Annular cutters are more efficient for larger holes, as they remove material quickly and generate less heat due to their cutting method.
Can annular cutters be used on wood?
A hole saw and an annular cutter are both cutting tools used to create holes in materials such as metal, wood, or plastic.

Can you mill with an annular cutter?
They don’t only make great hole saws but they also make fairly dandy face mills if you only take a small skim. Easy to sharpen too. The main purpose of the centre pin is to be able to centre the hole on the marked spot – it will pick up a dot punch mark easily !
How do you cut a deep hole?

What is the difference between carbide and HSS annular cutters?
Tungsten carbide tipped (TCT) TCT core drills are more expensive than HSS core drills but are faster and more efficient in making larger holes. TCT core drills are cheaper for bigger diameters i.e. above 41 mm. Tip breakage is more likely than with HSS core bits, and TCT bits may not be re-sharpened.
Do annular cutters work on stainless steel?
Annular cutters are designed to cut through a wide range of metals, including steel, stainless steel, cast iron, aluminium, brass, and copper. Because of this variety, manufacturers produce cutters from different materials, suited to a range of different applications.
What is HSS annular cutter?

Do you need a pilot pin for an annular cutter?
Pilot pins are essential for the use of annular cutters, as they provide the following practical uses: Use the appropriate cutting lubricant; oil, spray or paste.
Which tool is used for cutting deep holes in wood?

How much does a HSS annular cutter cost?
So, you’re looking into annular cutters for your hand drill, huh? That’s a smart move! These handy tools are perfect for drilling precise holes in a variety of materials, especially when you need a clean, perfectly sized hole.
But with all the different types and sizes available, it can be a bit overwhelming to choose the right one. Let me guide you through the world of annular cutters!
What are Annular Cutters?
Imagine a donut-shaped blade with a central core. That’s essentially what an annular cutter is. Instead of removing material from the center like a standard drill bit, an annular cutter cuts a ring-shaped hole around the core.
Why Use Annular Cutters?
Precision: These cutters are designed to cut clean, accurate holes with consistent diameters. No more struggling with wobbly bits or uneven cuts!
Versatility: You can use them on various materials, including wood, metal, plastic, and even fiberglass.
Efficiency: Annular cutters are faster and easier than using multiple drill bits to achieve the desired hole size.
Types of Annular Cutters
1. High-Speed Steel (HSS): This is the most common type of annular cutter, known for its durability and affordability. They work well on various materials, but they might need sharpening over time.
2. Carbide-Tipped: These annular cutters feature carbide teeth, making them incredibly strong and long-lasting. They can handle tougher materials and offer a longer lifespan than HSS cutters.
3. Bi-Metal: As the name suggests, these cutters combine high-speed steel with a carbide edge. This combination gives them the strength of carbide and the affordability of HSS. They’re a good option for occasional use on a variety of materials.
Choosing the Right Annular Cutter
Material: Consider the material you’re going to drill. HSS cutters work well for most materials, but carbide-tipped cutters are necessary for tougher materials.
Hole Size: Determine the exact diameter of the hole you need. Annular cutters come in a wide range of sizes, so you’ll find one that’s perfect for your project.
Depth: Decide how deep you need to drill. Annular cutters come in various lengths, so select one that’s long enough for your project.
Using Annular Cutters
1. Secure the Material: Clamp your workpiece securely to a workbench or use a vise. This ensures stability and prevents the workpiece from moving while you’re drilling.
2. Center Punch: Use a center punch to mark the center point of the hole. This helps guide the annular cutter and prevents it from wandering.
3. Start Slowly: Begin drilling at a slow speed and gradually increase it as the cutter bites into the material. This helps prevent the cutter from overheating and ensures a smooth cut.
4. Apply Pressure: Apply gentle but firm pressure as you drill. Don’t force the cutter, as this can lead to breakage or uneven cuts.
5. Lubricate: Lubricating the cutter with cutting oil or water helps keep it cool and improves cutting performance.
Safety Precautions
Always wear eye protection. Flying debris can be hazardous.
Use gloves to protect your hands.
Keep your hands clear of the rotating cutter.
Be careful when removing the workpiece. The cutter might still be rotating.
Annular Cutter vs. Hole Saw:
Both annular cutters and hole saws are used to create circular holes. However, they have some key differences:
Annular Cutters: They are more precise and offer a cleaner cut, making them ideal for projects requiring high accuracy.
Hole Saws: They are generally faster and better for drilling larger holes. They are also more versatile, capable of cutting various materials.
Maintenance
Clean: Clean the cutter with a wire brush or cleaning fluid after use.
Sharpen: Sharpen HSS cutters when necessary. Carbide-tipped cutters typically don’t need sharpening.
