Drill America CTH4250 hole cutter

The Drill America CTH4250 is a carbide tipped hole cutter built for pneumatic tools. It serves technicians who need to bore large diameter holes in metal without oversized chucks or heavy twist drills.

Auto ejecting slug with pilot drill

Each cutter includes a pilot drill and hex key for quick setup. The auto ejecting slug clears the cut piece automatically, reducing downtime and keeping the work area clean during repetitive drilling tasks.

Questions about this item

What size pilot drill does the CTH4250 hole cutter include?

Each cutter ships with its own pilot drill and a hex key, so the correct pilot is already in the box and no separate purchase is needed.

What shank style fits the 4-1/4" carbide tipped hole cutter?

The cutter uses a standard shank that fits directly into a magnetic drill press or a drill motor with a matching arbor, requiring no oversized chuck.

How do you install the pilot drill before cutting?

Insert the supplied pilot drill into the cutter's centre hole, tighten it with the included hex key, then engage the auto-eject slug feature so the slug releases cleanly after each hole.
