Drill America CTH4625 hole cutter

The Drill America CTH4625 is a carbide tipped hole cutter built for pneumatic tool users who need to drill large diameter holes without oversized chucks. It suits metal fabricators, maintenance technicians and automotive specialists cutting stainless steel, cast iron, sheet metal, copper and abrasive composites.

Thermal and power behaviour in use

Carbide tipped teeth reduce friction and heat buildup during extended cutting in stainless steel plate. The design maintains consistent performance through over 300 holes in stainless steel without the thermal fade common in standard bi metal cutters. Pneumatic drive delivers steady torque without motor overload.

Pilot drill and hex key included

A pilot drill is supplied to centre the cutter and prevent walking on curved or slippery surfaces. The hex key allows quick pilot drill changes or depth adjustments without hunting for separate tools. Auto ejecting slug clears the cut core automatically, keeping the work area clear and reducing downtime between holes.

Questions about this item

How do I install the pilot drill on the CTH4625 hole cutter, and what step is often missed?

Insert the supplied pilot drill into the cutter body and tighten the set screw using the included hex key; the step often missed is fully securing that screw before cutting.

What maintenance or replacement will the CTH4625 need after extended use?

The carbide-tipped teeth and pilot drill will eventually wear; replace the pilot drill when it dulls, and the cutter once the teeth no longer cut cleanly.

What limit appears first when using the CTH4625 continuously in stainless steel?

The cutter is rated for over 300 holes in stainless steel plate; tooth wear and slug ejection reliability become the limiting factors beyond that count.
