Silver metal annular cutter with Weldon flat shank

Slugger By Fein

Slugger By Fein 63134318041 Annular Cutter pneumatic accessory

SKU CH-QGKJ-CDQB9

High-speed steel annular cutter with Weldon flat shank for 1-inch maximum cutting depth

  • High-speed steel construction resists wear during heavy drilling
  • Weldon flat shank locks securely in magnetic drill chucks
  • 1-1/4 inch diameter creates precise large holes in metal
  • One inch cutting depth handles thick plate in a single pass
  • Bright finish reduces friction and improves chip evacuation

Annular Cutter For Magnetic Drills

This Slugger By Fein annular cutter is designed for magnetic-base drilling machines that accept a 3/4 in Weldon Flat shank. It produces a 1 1/4 in diameter hole with a maximum cutting depth of 1 in. The high-speed steel body suits general-purpose metal fabrication and maintenance tasks where a solid twist drill would be impractical.

Sustained Cutting In Steel

The high-speed steel construction maintains hardness during extended cuts in structural steel and plate. Chip evacuation through the annular geometry reduces binding compared with solid drills at the same diameter. Consistent feed pressure yields repeatable hole quality across multiple workpieces without frequent tool changes.

Heat And Wear Characteristics

Bright finish provides no coating barrier, so cutting fluid is essential to manage temperature at the cutting edges. Proper lubrication limits thermal expansion that can seize the slug inside the cutter. Power draw and vibration remain low relative to twist drilling because only the perimeter material is removed.

Questions about this item

How much air pressure and volume does the 63134318041 annular cutter need to run continuously without overheating?

The cutter is driven by a pneumatic tool; the air supply must match the tool’s rated pressure and CFM, which are set by the tool manufacturer, not by the cutter itself.

What shank size must my magnetic drill or drill press accept to hold the 3/4 in Weldon Flat shank on this cutter?

The cutter has a 3/4 in diameter Weldon Flat shank, so the machine’s arbor or chuck must accommodate that exact shank diameter and flat profile.

Can I use this 1 1/4 in diameter cutter on a magnetic base drill that only accepts 1/2 in shank cutters?

No, the 3/4 in Weldon Flat shank will not fit a 1/2 in shank arbor; you would need an adapter or a machine with a 3/4 in capacity.
