Morse CTD46 Carbide Tipped Hole Cutter 73mm

The Morse CTD46 is a carbide tipped hole cutter with a 73mm diameter designed for precision holes in thicker sheet metal and plate applications. It suits metalworkers and fabricators who need clean, fast cuts in heavy gauge material.

Upgrading from standard bi-metal hole saws

Standard bi-metal saws can wear quickly in thick plate and often leave rough edges or bind on breakthrough. The ground tooth profile and shouldered cutter body reduce breakthrough impact and prevent pass through, making the jump worthwhile when cut quality and tool life in heavy material matter most.

Build integration: pilot drill.

The cutter uses a CTDP 16700 pilot drill and a CTDS 167017 ejector spring, both available as replacement parts. A grooved gullet directs chips up and away from the cut while the spring aids slug removal, freeing the operator from frequent stoppages to clear debris.

Questions about this item

What shank or arbor size does the Morse CTD46 73mm cutter need to mount on a drill press or mag drill?

The cutter uses a standard Morse taper shank that fits directly into compatible mag drills or drill-press arbors; match the machine's taper size to the cutter's shank for a secure fit.

How do I install the pilot drill and ejector spring, and what step do users often miss?

Insert the CTDP 16700 pilot drill through the cutter's centre hole until it seats, then slide the CTDS 167017 ejector spring over the pilot; the step often missed is tightening the pilot-drill set screw so it cannot spin or back out during cutting.

Which replacement parts will I need later for the Morse CTD46 73mm hole cutter?

Keep the CTDP 16700 pilot drill and CTDS 167017 ejector spring on hand; the pilot dulls first and the spring loses tension after heavy use, so replacing both restores clean slug ejection and accurate centering.
