- Fast and Efficient Cutting Performance: Annular bits drill large holes up to ten times faster than regular drill bits, featuring thin-walled construction with dual alternating teeth for aggressive cutting that requires less force and time compared to traditional hole saws and twist drill bits
- Re-Sharpenable HSS Construction: High Speed Steel Slugger Bits deliver burr-free and smooth holes with higher accuracy, multiple cutting edges for ply-cutting, and lower friction for better endurance and efficient chip removal, resulting in less material wastage
- Universal Compatibility: Features 3/4" Weldon shank with 2 flats that fits most standard magnetic drills and machine tools such as mills and large drill presses with tool holders for versatile applications
- Versatile Material Applications: Suitable for working with both ferrous and non-ferrous metals, cast iron, stainless steel, aluminum, copper, plastic, and wood in either plate or pipe form, including applications in engineering, rail transit, bridges, ships, machinery manufacturing, and aerospace industries

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
Annular Cutters cut only the periphery of the hole,ejecting the remaining center as a slug.It produces accurate burr-free holes to close tolerances without pre-drilling or step drilling.
Best used with a drill press or magnetic drilling machine, both for their stability against high torque forces created by such a drill bit and lower RPMs compared to other types of drills. these cutters can be easily used with light duty drilling machines or portable magnetic base drilling machines.
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.
Heavy‐Duty Annular Drill Bits – Rigid 2‐Flat Holder, Optimized Flute Design for Faster Cuts
Complete 13-piece set – 11 cutters covering diameters from 7/16′′ to 1-1/16′′, plus 2 pilot pins – everything you need for a wide range of hole sizes
Drill holes up to 10× faster than traditional twist drills – thin-walled design removes only the periphery, not the entire hole
2′′ depth of cut – one pass through thick plate, structural steel, and heavy pipe-
Burr-free, ready-to-use holes – no secondary deburring or finishing required-3
Re-sharpenable HSS cutters – extends tool life and reduces replacement costs-3
Industry-standard 3/4′′ Weldon shank – fits most magnetic drill presses (Hougen, Nitto Kohki, Euroboor, Fein, DeWalt, Milwaukee)
Processing
Aplication
Suitable for working with both ferrous and non-ferrous metals,cast iron, stainless steel, aluminum,copper,and plastic,wood, in either plate.
Annular Cutters can also be best used to make holes in pipes and tubes. Annular cutters help make holes in pipe and tubes without dimpling and deburring.
Processing Field
processing field such as engineering,rail transit, bridges, ships, machinery manufacturing, aerospace. Mild & Structural Steel.
Attention
During the drilling process, the pilot pin will retract into the cutter allowing lubrication to reduce heat gain in the slug.
Insert the ejector pin inside the annular cutter,never use an annular cutter without an ejector pin.
Using lubricant or coolant with any type of annular cutter is a must. A correct lubrication and coolant delivery more life for annular cutters. HSS annular cutters required Cutting oil, not coolant.
Questions & Answers
Q1: Will this annular cutter fit my magnetic drill press? A: Yes – if your magnetic drill press accepts 3/4′′ Weldon shank tooling with 2 flats . This fits most brands including Hougen, Nitto Kohki, Euroboor, Fein, DeWalt, Milwaukee, and generic shop brands. Not for handheld drills.
Q2: What are the exact dimensions? A: Cutting diameter: 7/16inch, 1/2inch, 9/16inch, 5/8inch, 11/16inch, 3/4inch, 13/16inch, 7/8inch, 15/16inch, 1inch, 1-1/16inch. Depth of cut: 2′′. Shank: 3/4′′ Weldon with 2 flats.
Q3: Does this cutter come with a pilot pin? A: Yes. This cutter comes with a pilot pin for accurate positioning before drilling.
Q4: Can I use this on a standard drill press or handheld drill? A: No. Annular cutters are designed for magnetic drill presses only – they require the specific low RPM, high torque, and coolant delivery of a mag drill. Using them on other machines will result in poor performance and potential breakage.
Q5: What materials can I drill? A: Mild steel, structural steel, stainless steel (with proper oil), cast iron, aluminum, copper, brass, and plastic. Not for hardened steel, abrasive composites.
Q6: What lubricant should I use? A: Cutting oil – NOT coolant . Apply through the arbor slots with the magnet ON and motor OFF. Water-based coolants cause thermal shock and reduce HSS tool life.
Q7: How do I remove the slug after drilling? A: Remove the cutter from the drill, then use a standard punch or an ejector pin (sold separately) inserted from the shank end to push out the slug. The cutter does not include an ejector.
Q8: How long does the cutter last? Can it be resharpened? A: Life depends on material and use – typically hundreds of holes in mild steel. Yes, it is re-sharpenable – grind on a grinding machine until the cutting length is reduced.
Q9: What does “precision ground” mean? A: Precision-ground edges ensure superior cutting performance, cleaner holes, and extended tool life compared to standard ground cutters.
Q10: My holes are rough or oversized – what could be wrong? A: Check: insufficient cutting oil, dull teeth, incorrect speed, loose shank, or debris in the cutter. Also ensure you used a center punch for proper positioning.
Q11: Does it come with a storage case? A: No. It comes as a single cutter. Store in a protective sleeve or tool box to protect the teeth.
Q12: Is this compatible with Hougen mag drills? A: Yes – Hougen uses the standard 3/4′′ Weldon shank with 2 flats, so it fits directly.
