Several brands of annular hole cutters are available from Miller’s Tooling Pty Ltd. An annular cutter is used heavily in the fabrication & construction industry. Annular hole cutters are run in magnetic base drills, ideal for site work. Drilling beam & RHS, plate, etc.
The standard annular cutters can range in depth of cut into steels. The annular hole cutters rely
on an ejector pin thru the centre to eject the waste slug thru the hole, (no sticking scrap, like holesaws) cutting oil or coolant is essential to assist cutting. Most magnetic base drills do have a small coolant container attached.
Annular hole cutters can easily be adapted to conventional drilling machines & milling machines simply with a Morse Taper, rotary coolant adaptor, also readily avail from Miller’s Tooling.
Mini annular hole cutters can be drilled in elec. pedestal drills or portable hand drills 
with a 3/8” or
½” shank arbor.
¼” mini cutters are great for any shop or handyman, avail in mini kits 8 – 20mm.
Also in kits, cutting depth of ½”, kits have 10 – 25mm avail, also individual hole cutters & arbors avail.
Standard annular hole cutters come in 25mm depth cutter, 50mm depth, 75mm depth & even 100mm depth of cutting.
The main advantages of drilling holes with an annular hole cutter;
1) 3 x faster than a drill (removing only outer diameter in swarf)
2) Longer tool life than a drill (less heat/friction than a drill)
3) 10 x faster than a conventional hole saw
4) 300 x life, compared to a holesaw
5) Cutting thru round pipe & tube without wandering
6) Notching pipe, tube, RHS etc.
