Slugger by Fein Annular Cutter 63134539003 2-1/8 Inch (3 Inch Depth M2 HSS Magnetic Drill Press Bit 3/4 Inch Weldon Shank Structural Steel)

Slugger by Fein 63134539003 2-1/8-Inch x 3-Inch M2 HSS Annular Cutter

The Slugger by Fein 63134539003 2-1/8-Inch x 3-Inch M2 HSS Annular Cutter is an industrial core drilling bit engineered to bore precise 2-1/8-inch diameter holes through structural steel plate, mild steel, and non-ferrous metals up to 3 inches thick. Manufactured in the USA from premium M2 high-speed steel with a 3/4-inch Weldon flat shank and CNC-ground cutting geometry, this tool removes material strictly along the perimeter of the cut. Designed for portable magnetic drill presses and stationary drill machines, this annular cutter solves slow cycle times, heavy horsepower draw, and rough burr formation across commercial steel fabrication and bridge construction jobsites.

Best Used For:

• Deep Structural Steel I-Beam Drilling: Boring clean, reamed-quality 2-1/8-inch bolt holes through 3-inch thick structural steel beams and heavy gusset plates.
• Overlap & Curved Surface Hole Cutting: Executing smooth overlapping hole modifications or cutting clean profiles across curved steel pipe and tank walls.
• High-Speed Magnetic Drill Production: Achieving 3X to 5X faster hole completion rates on jobsite locations using portable magnetic drills with 3/4-inch Weldon chucks.

Key Performance & Safety Features

• Premium M2 High-Speed Steel Build: USA-made M2 HSS alloy construction maintains superior cutting edge hardness under severe friction and heat.
• 3-Inch Deep Core Cutting Capacity: Extended barrel depth capacity permits single-pass drilling through thick metal stock without step-drilling.
• 3/4-Inch Weldon Flat Shank: Universal dual-flat Weldon shank locks securely into magnetic drill spindles to eliminate rotational slippage.
• Reamed-Quality Burr-Free Hole Finish: Perimeter-only cutting action leaves smooth, burr-free bore walls to eliminate secondary reaming operations.
• CNC-Ground Resharpenable Tooth Profile: Precision CNC-ground cutting edges promote efficient chip evacuation and can be resharpened to extend tool service life.

What's Included

• (1) Slugger by Fein 2-1/8 in. x 3 in. M2 HSS Annular Cutter (63134539003)

Technical Specifications

Pro-Tip: Always use a liquid cutting lubricant or internal coolant system with Pilot Pin 16005 when making 3-inch deep cuts to clear internal swarf and force the solid steel slug out cleanly.
