Electrician carbide hole cutter kit

The Morse CTS02 kit supplies nine carbide-tipped cutters covering the common conduit and pipe entry sizes electricians use daily. Diameters run from 7/8 inch (22 mm) through 2-1/2 inch (64 mm) in six steps, so a single case handles most junction-box and panel knock-outs without hunting for individual bits.

Six diameters from 22 mm to 64 mm

The spread covers 22, 29, 35, 44, 51 and 64 mm holes, matching standard trade knock-outs for cable, conduit and pipe. Larger diameters beyond 64 mm or finer increments between the listed sizes are not included, so jobs requiring non-standard or oversized openings will need separate cutters.

Stepped pilot drill, ejector spring

The kit adds replacement parts CTSP (166010) stepped pilot drill, CTSS (166027) ejector spring and a hex key, letting you refresh the pilot and clear slugs without downtime. No lubricant, carrying case beyond the factory packaging, or additional arbors are supplied.

Questions about this item

Will the 22 mm cutter fit the arbor from my older Morse kit?

The kit includes a CTSP stepped pilot drill (166010) that mounts on the arbor; if your existing arbor accepts that pilot it will work.

How do I know each cutter is cutting cleanly after I install the pilot and spring?

A clean, burr-free hole at the marked diameter — 29 mm, 35 mm, 44 mm, 51 mm or 64 mm — with the ejector spring (166027) pushing the slug out confirms correct setup.

Does the case contain the hex key and ejector spring, or must I buy them separately?

The 9-piece kit (166737) ships with one CTSP pilot drill (166010), one CTSS ejector spring (166027) and the hex key included.
