FEIN Annular Cutter 63134302041 1-3/16 Inch Diameter 1 Inch Depth HSS (3/4 Inch Weldon Shank Pilot Pin Magnetic Drill Metal Fabrication Tool)

FEIN 63134302041 1-3/16-Inch High-Speed Steel Annular Cutter with Pilot Pin

The FEIN 63134302041 1-3/16-Inch HSS Annular Cutter delivers fast, burr-free hole production through structural steel beams, plate iron, and non-ferrous metals. Manufactured from heavy-duty high-speed steel with a 1-inch cutting depth capacity, this core cutter removes only the peripheral ring of material to reduce thrust load on portable magnetic drill presses. The included precision pilot pin aligns the cutting face on layout marks and powers automatic solid core slug ejection upon breakthrough.

Best Used For:

• Structural Steel Fabrication: Boring accurate 1-3/16-inch connection bolt holes through heavy wide-flange I-beams and gusset plates.
• Weld Joint Preparation: Sizing cylindrical relief cuts and perimeter access holes in thick carbon steel plates without edge hardening.
• Field Machinery Maintenance: Retrofitting industrial frames and mounting brackets on-site using portable magnetic base drills.

Key Performance & Safety Features

• High-Speed Steel Metallurgy: Heavy-duty German-engineered HSS construction withstands abrasive wear and thermal breakdown during production drilling.
• Peripheral Annular Geometry: Displaces three to five times less stock than twist drills, significantly lowering motor amperage draw and cutting cycle time.
• 3/4-Inch Straight Weldon Shank: Dual drive flats provide slip-free rotational torque transmission across industrial magnetic drill chucks.
• Burr-Free Edge Finish: Precision ground tooth geometry eliminates the need for secondary reaming or mechanical deburring passes.
• Centering & Ejection Pilot Pin: Channels internal cutting fluid directly to the tooth tips and ejects the solid center slug cleanly after breakthrough.

What's Included

• (1) FEIN 63134302041 1-3/16-Inch HSS Annular Cutter (1-Inch Cutting Depth)
• (1) Centering & Slug Ejection Pilot Pin

Technical Specifications

Pro-Tip: Always maintain steady internal coolant pressure through the pilot pin arbor when magnetic drilling; proper lubrication prevents chip welding in the gullets and ensures the steel slug pops out instantly at the bottom of the cut.
