OSCARBIDE 1-1/4"x1 HSS Annular Cutter 3/4" Weldon Shank Mag Drill Bit
- Annular Cutter Specifications: 1-1/4" Cutting Diameter, 1" Cutting Depth, 3/4" Weldon Shank with 2 Flat, Pilot Pin Size: 6.34x77mm
- Fast and Efficient Drilling: OSCARBIDE Annular bits drill large holes up to ten times faster than regular drill bits, with thin-walled design and dual alternating teeth for aggressive cutting that is easier than traditional hole saws and twist drill bits, requiring less force and time
- High Performance HSS Construction: These HSS Slugger Bits feature re-sharpen ability and create burr-free smooth holes, resulting in less scrap and wastage of material, with higher accuracy and multiple cutting edges for ply-cutting and lower friction to reach better performance of endurance and removal of chips
- Universal Compatibility: OSCARBIDE annular Bit fits most standard magnetic drills and machine tools such as mills and large drill presses with tool holders
- Versatile Material Applications: These annular cutters are 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 hole processing fields such as engineering, rail transit, bridges, ships, machinery manufacturing, aerospace, mild and structural steel

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.
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 such as engineering,rail transit, bridges, ships, machinery manufacturing, aerospace. Mild & Structural Steel.
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.
Will this annular cutter fit my magnetic drill press?
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.
What lubricant should I use?
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.
How do I remove the slug after drilling?
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.
How long does the cutter last? Can it be resharpened?
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.
My holes are rough or oversized – what could be wrong?
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.
