OSCARBIDE Annular Cutter Set 7pc, 1" Depth, 3/4" Weldon Shank
- Complete 7-Piece Set for Versatility: Includes cutters in 6 essential diameters: 1/2", 9/16", 11/16", 13/16", 15/16", and 1-1/16". All with 1" cutting depth and 1 pilot pin(1/4"x3") for heavy-duty use
- Up to 10x Faster & Burr-Free Holes: Thin-wall annular cutter design removes only the outer ring of material, not the entire hole. This delivers up to 10 times faster drilling speed than twist bits and produces clean, burr-free holes without secondary finishing
- Heavy-Duty M2 High-Speed Steel: Crafted from premium M2 HSS with precision-ground teeth, these cutters offer excellent wear resistance and heat resistance for extended tool life, and they're re-sharpenable to maximize your investment
- Universal 3/4" Weldon Shank with Pilot Pin: Features a standard 3/4" Weldon shank with 2 flats, fitting most magnetic drill presses. The included pilot pin ensures accurate hole starting and positioning while allowing coolant to flow to the tip
- Cost-Effective Solution: Delivers professional-grade performance at a fraction of the cost of leading brands. Suitable for metal fabricators, structural steel workers, and serious DIY enthusiasts
- Durable Storage Case Included: Comes with a protective storage case to keep all cutters organized and protected from damage, ensuring easy transport and long-lasting tool condition

Premium Material
Made with premium high speed steel material, for longer service life and high heat resistance,the biggest advantage of HSS core drill is its ability to re-sharpen.
Features:
10× Faster Drilling – Unlike twist drills that grind away the entire hole, annular cutters remove only the periphery, ejecting the center as a solid slug. The thin-walled design with dual alternating teeth enables aggressive, efficient cutting— up to ten times faster than traditional drill bits.
Burr-Free, Precision Holes – The unique geometry produces accurate, burr-free holes to close tolerances without pre-drilling or step drilling. No secondary finishing operations required—drill and move on.
Time saving:The annular cutters have fewer teeth and less wear, therefore with an annular cutter holes can be made at higher or faster cutting speed and a faster feed rate of the drilling machine.
Energy savings:Because annular cutters do not have to drill/cut through the complete work piece, they require less thrust and thus less energy to drill through material.
More finishing:The hole made using an annular cutter is more finished, precise and accurate.
Easy Using:Due to the unique geometry of the annular cutters, making holes at awkward angles is also very easy.
Re-sharpening:can be easily re-sharpened on a grinding machine and can be re-used for drilling. Re-grinding can be done until the desired cutting length is available on the annular cutter
Value to You
Metal Fabricator / Ironworker : Cut structural steel holes in seconds instead of minutes. One set covers the most common 1/2′′ to 1-1/16′′ hole sizes for beam connections, pipe flanges, and equipment mounting.
Maintenance / Repair Technician : Drill through stainless, cast iron, and hardened materials with minimal effort. Less thrust required means easier operation on portable magnetic drills.
Bridge / Shipbuilding / Aerospace : Produce high-precision, finished holes in mild and structural steel — no secondary deburring required.
DIY / Workshop Owner : One versatile set handles metal, wood, and plastic projects. The 1′′ cutting depth covers most common material thicknesses.
Heavy‐Duty Annular Drill Bits – Rigid 2‐Flat Holder, Optimized Flute Design for Faster Cuts
Precision Cutting Teeth Minimize Chatter, Lower Power Draw, and Ensure Superior Surface Quality
Processing:
1.Q: What magnetic drill presses are compatible with these cutters?
A: These annular cutters feature a 3/4′′ Weldon shank with 2 flats — the industry standard for magnetic drill press tooling-1. They are compatible with most major magnetic drill brands including:Hougen,Nitto Kohki,Euroboor,Fein,DeWalt,Milwaukee,Generic / shop-brand magnetic drills
Important : These cutters require a magnetic drill press or mill drill — they are NOT compatible with standard handheld drills-2. If your machine accepts 3/4′′ Weldon shank tooling with 2 flats, these cutters will fit.
2.Q: How much faster are annular cutters than twist drills?
A: Annular cutters can drill large holes up to ten times faster than traditional twist drill bits. Here‘s why:
Less material to remove — Annular cutters remove only the periphery (the “ring”) of the hole, ejecting the center as a solid slug. Twist drills must grind away the entire hole volume.
Less thrust required — Less material removal means less force needed, reducing operator fatigue and extending tool life.
Faster cutting speeds — Fewer teeth and less wear allow for higher cutting speeds and feed rates.
3.Q: How does the pilot pin work?
A: The pilot pin serves as a guide to ensure accurate hole placement. During drilling:
1.The pilot pin centers the cutter on the marked location.2.As the cutter penetrates the material, the pilot pin retracts into the cutter body.3.This retraction allows cutting fluid to reach the cutting zone and lubricate the slug.
Always use the pilot pin — it ensures accurate hole placement and protects the cutter from lateral stress.
4.Q: How do I remove the slug after drilling?
A: Each annular cutter set includes an ejector pin-2. After drilling:
1.Remove the cutter from the drill press.2.Insert the ejector pin into the cutter from the shank end.3.Tap or press the ejector pin to push the slug out of the cutter.
5.Q: What lubricant should I use?
A: Use cutting oil — NOT coolant -2. HSS annular cutters require cutting oil for:
Heat reduction during drilling;Extended tool life;Improved hole quality
Pro tip : Apply cutting fluid through the slots in the arbor with the magnet ON and motor OFF for proper lubrication-.
6.Q: Can these cutters be resharpened?
A: Yes — these HSS annular cutters can be easily re-sharpened on a grinding machine. The cutters can be re-ground multiple times until the desired cutting length is reached. This re-sharpenable design:Reduces waste and consumable costs;Extends the useful life of each cutter;Makes the set a long-term investment
7.Q: How long do these cutters last?
A: Cutter life depends on the material and proper lubrication:
Mild steel : 500,000+ holes with proper cutting oil, Stainless steel : 200–400 holes — use slower feed and plenty of oil, Aluminum / copper : 1,000+ holes — fast, clean cutting
Signs it‘s time to sharpen: increased cutting resistance, rough hole edges, visible wear on the cutting teeth, or longer drilling times.
8.Q: My holes are rough or oversized — what‘s wrong?
A: Run through this checklist:
1. Check lubrication — Are you using cutting oil (not coolant)?2. Check feed rate — Are you feeding too fast or too slow?3. Check pilot pin — Is the pilot pin properly installed and retracting correctly?4. Check cutter condition — Are the teeth dull or damaged? Time to resharpen.5. Check material — Is the material harder than expected (e.g., hardened steel)?
