Product description

OSCARBIDE 1-9/16” Annular Cutter for Magnetic Drills – 10X Faster Cutting, Weldon Shank, Multi-Material Hole Saw

No pre-step drilling is required; holes are cut in as little as 15 seconds

Brand Name: OSCARBIDE

Material: High Speed Steel (HSS)

Weldon Shank: 3/4 inch

Cutting Depth: 1 inch

Cutting Diameter:1-9/16 inch

Number of Flats: 2

Pilot Pin Size: 1/4 inch x 3 inch(6.34x77mm)

Precision Engineering & Durability

• Laser-Hardened HSS: 65 HRC hardness resists deformation in 1,200°F steel cutting • Chipbreaker Grooves: Auto-eject metal shavings mid-drill to prevent jams • Reusable Design: Sharpen up to 8x with standard grinding tools (saves $47/cutter vs disposable)

Superior Speed & Efficiency

Engineered for tradesmen who value time, OSCARBIDE annular cutters drill cleaner 1-9/16” holes in seconds – not minutes. Our patented thin-wall design with dual carbide teeth bites deeper per rotation than clunky hole saws, requiring 60% less downforce.

• 10X Faster Drilling: Cut large holes 10x quicker than traditional drill bits with dual alternating teeth for aggressive metal.
• Zero Burr Precision: Laser-sharpened HSS slugger bits deliver smooth, burr-free holes (1-9/16” diameter x 1” depth) in steel/copper/plastic.
• 3/4” Weldon shank with 2 flats works with MagDrill, Hougen, Milwaukee & most magnetic drills/milling machines.
• Pro-Grade Durability: Tungsten-carbide tipped teeth + re-sharpenable design outlast hole saws in bridges, ships, aerospace projects.
• Thin-Wall Advantage: Slice through structural steel, stainless pipes, aluminum plates (6.34x77mm pilot pin for wobble-free starts).

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

Versatile Applications

Ideal for HVAC ducting, steel beam fabrication, shipyard repairs, and DIY metalworking. Cuts through: Mild steel,Stainless steel , Cast iron ,Aluminum sheets , PVC/ABS piping

Universal Compatibility

Fits all Weldon 3/4” shank magnetic drills and drill presses. Includes 6.34x77mm pilot pin for perfect alignment on curved pipes/uneven surfaces.

Attention

1. During the drilling process, the pilot pin will retract into the cutter allowing lubrication to reduce heat gain in the slug.
2. Insert the ejector pin inside the annular cutter,never use an annular cutter without an ejector pin.
3. 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: 1-9/16″. 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.

• Annular Cutter Size :1-9/16”Cutting Diameter,1"Cutting Depth, 3/4” Weldon Shank with 2 Flat,Pilot Piin Size: 6.34x77mm.
• OSCARBIDE Annular bits will drill large holes up to ten times faster than regular drill bits,and the mag drill bits are thin-walled and have dual alternating teeth for efficient and aggressive cutting that is easier than traditional hole saws and twist drill bits,It can drill a much larger hole and requires less force and time.
• These HSS Slugger Bit ability to re-sharpen and burr-free holes and smooth holes, resulting in less scrap and wastage of material,has higher accuracy and multiple cutting edges for ply-cutting and lower friction to reach better performance of endurance and removal of chips.
• OSCARBIDE annular Bit fits most standard magnetic drills and machine tools such as mills and large drill presses with tool holders.
• These annular cutters are suitable for working with both ferrous and non-ferrous metals,cast iron, stainless steel, aluminum, copper, and plastic,wood, in either plate or pipe form.Hole processing field such as engineering,rail transit, bridges, ships, machinery manufacturing, aerospace.
