Brand Name: OSCARBIDE
Material: High Speed Steel (HSS)
Weldon Shank: 3/4 inch
Cutting Depth: 1 inch
Cutting Diameter: 2 inch
Number of Flats: 2
Pilot Pin Size: 1/4 inch x 3 inch(6.34x77mm)
OSCARBIDE annular cutter removes only the outer ring of material—not the entire slug. Less resistance means faster cutting, less wear on your drill, and a hole that's ready to use the moment you pull the bit out.
Cut Holes 10× Faster – Say Goodbye to Slow, Frustrating Twist Drills
Long-Life HSS That Keeps Cutting
Premium HSS maintains cutting hardness up to 650°C – stays sharp longer in high-heat drilling
Can be re-sharpened 5–7 times before replacement – each cutter delivers hundreds of holes
Carbon steel cutters lose hardness above 200°C and dull rapidly in steel applications
Your Savings : One OSCARBIDE cutter = 3–5 standard carbon steel cutters in total hole count
Mount: Insert the 3/4" flat shank into your mag drill chuck. Tighten the set screw—double-flat design prevents slipping.
Position: Lock the mag drill onto the workpiece. Align with your hole location—no center punch needed.
Feed: Start the drill. Apply steady pressure—the annular design self-centers, no pilot hole required.
Cut Holes in 15 Seconds Body: 80% faster than traditional hole cutting methods
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
Precision Cutting Teeth Minimize Chatter, Lower Power Draw, and Ensure Superior Surface Quality
Drill holes up to 10× faster than traditional twist drills – thin-walled design removes only the periphery, not the entire hole
Burr-free, ready-to-use 2′′ holes – no secondary deburring or finishing required
1′′ depth of cut in one pass – through most plate, structural steel, and pipe
Industry-standard 3/4′′ Weldon shank – fits most magnetic drill presses (Hougen, Nitto Kohki, Euroboor, Fein, DeWalt, Milwaukee)
Re-sharpenable HSS body – extends tool life and reduces replacement costs
Compatible Magnetic Drills – Industry Standard Fit
Quick‐Start Guide – Get to Work in Minutes
Mount – Insert the shank into your magnetic drill's chuck. Align the two flat faces with the set‐screws and tighten with a hex wrench.
Position – Mark your hole center on the workpiece. Use the pilot pin to align the cutter precisely over the mark.
Activate magnet – Switch on the magnetic base. Confirm the green indicator light is on (minimum workpiece thickness recommended: ≥8mm / 5/16").
Start drilling – Turn on coolant. Begin with a slow feed for the first 1‐2mm, then advance at a steady, moderate rate. Do not force – let the cutter do the work for longest life.
Remove slug – After completing the hole, tap the pilot pin lightly to eject the slug from the Pro Tip : When drilling steel, always use adequate cutting fluid. Heat is the #1 enemy of HSS tooling – keep it cool and it will keep cutting.
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.
Applicable Material Rating and Machine
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: 2′′. Depth of cut: 1′′. 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: How much faster is this than a twist drill? A: Annular cutters can drill holes up to ten times faster than regular drill bits. The thin-walled, dual-alternating-tooth design provides efficient and aggressive cutting.
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.
