  • Rated for over 300 holes in stainless steel plate

4-1/8" Carbide Hole Cutter

The Drill America CTH4125 is a pneumatic accessory designed to bore large-diameter holes without oversized drill bits or chucks. Its carbide-tipped teeth on a high-speed steel body give extended service life in tough materials. An auto-ejecting slug clears the workpiece after each cut. A pilot drill and hex key are included for immediate use.

Best for stainless and thick plate

This cutter suits operators drilling stainless steel, cast iron, sheet metal, copper or abrasive composites such as high-density resin. It handles repetitive production where over 300 holes in stainless plate are expected. It is not for handheld drills lacking a pneumatic drive or for jobs needing diameters outside 4-1/8".

1" depth of cut

The single specification that decides fit is the 1" maximum cutting depth. If your material exceeds that thickness you must select a deeper-reach cutter or use a different method.

Questions about this item

How much vibration and heat does the 4-1/8" carbide tipped hole cutter generate during extended use in stainless steel?

The cutter is designed for efficient material removal in stainless steel, cast iron and other metals, and its carbide tipped teeth provide extra long lifespan over 300 holes, reducing the need for frequent changes.

What drive tool and air supply are needed to run this carbide tipped hole cutter?

Each cutter includes a pilot drill and hex key for installation, and it is built for use with pneumatic magnetic drills or portable drill presses that accept the cutter's shank.

Will the 4-1/8" cutter fit the same pilot drill and hex key I already use with smaller Drill America cutters?

Every cutter in the line ships with its own pilot drill and hex key, so you can swap sizes without hunting for separate accessories.
