4-11/16" Carbide Tipped Hole Cutter

The Drill America CTH4687 is a pneumatic accessory built for cutting large-diameter holes without oversized chucks. It suits metalworkers and maintenance crews who need clean bores in tough alloys. The carbide-tipped teeth extend service life on stainless steel, cast iron, copper and abrasive composites.

1" depth of cut and 300-hole capacity

Each cutter reaches a 1-inch depth of cut and can produce over 300 holes in stainless steel plate before replacement. An auto-ejecting slug clears the workpiece automatically, keeping the workflow moving. The pilot drill and hex key are included so the tool is ready for immediate use.

Upgrade from bi-metal hole saws

This cutter replaces slower bi-metal hole saws that wear quickly on hard materials and require larger chucks. The jump is worth it when repeatability in stainless steel, high-density resin or thick metal plates matters. It is not for jobs needing deeper penetration or diameters outside the 4-11/16" specification.

Questions about this item

Will the 4-11/16" carbide-tipped hole cutter fit the standard arbor on my existing magnetic drill press?

The cutter uses a 1" depth-of-cut design with an included pilot drill and hex key, matching common magnetic-drill arbors for direct mounting.

How do I confirm the auto-ejecting slug mechanism is functioning correctly after the first cut?

After drilling, the slug should pop free automatically; if it remains stuck, clear debris from the ejection spring and verify the pilot drill is seated to full depth.

Does the package include the pilot drill and hex key, or must they be purchased separately?

Each cutter ships with both the pilot drill and hex key in the box, so no extra accessories are required to start cutting.
