Klein Conduit Fitting and Reaming Screwdriver

Cutting conduit leaves sharp edges that can nick and penetrate wire insulation, especially when pulling wire. The rough edges also can make it difficult to attach fittings. Klein makes a screwdriver specifically for reaming conduit. As a bonus they also provide a hood around the screwdriver blade, to make tightening conduit fittings easier.

The reamer cleans both the inside and outside of 1/2″, 3/4″, and 1″ conduit with a replaceable reaming blade. A 1/16″ hex socket set screw holds the reaming blade in place. Klein designed the screwdriver’s thick, hooded screwdriver blade to hold up to the most demanding jobs. The hood surrounds the fitting screw head, so the standard screwdriver blade doesn’t slip from the screw. Of course, Klein claims their distinctive, cushion-grip handle provides both comfort and more reaming torque.

Expect to pay anywhere from $18 to $30 for this tool. Greenlee makes an almost identical tool for around $20.

    This is a great time saving tool! I have one that I use every day when installing EMT conduit; it only works on EMT / thinwall conduit. The best part is that you only need one screwdriver if you are using set screw connectors and couplings.

    Klein also sells just the tool head.

    My electrical sub usually comes with one of these plus bags of anti-short bushings. I guess that between pulling lubricant and a cleaned-up edge there is less chance of insulation damage.

    As a plumber – I wouldn’t think of installing pipe without reaming and we carry spiral reamers (hand ratcheting) for clean-up and our threading machines (even my old Oster) have on-board reamers that you swing into place after threading. Most quality tubing cutters also have reamers built-in.
    We even ream PEX cuts – seems to make the expanding tool work easier.

    I bought one of these a WHILE ago, and haven’t used it but once, and I used it only for the reason I spent $25 on it. Hardly use any EMT in commercial and residential, don’t plan on going into industrial.

    Only buy one if you use EMT a LOT. A pair of of old pliers (almost any kind that fit) do the job faster and easier. A small file also cleans it up better than the reamer.

    Jason – your correct – if we only only bought what we need on a regular basis we would not have so many tools that sit gathering dust. We have plenty of oddball plumbing tools waiting for the next special job. In point of fact – it probably would have made more sense not to have bought them and have figured out some other work around. I have lots of big (2 inch and higher) pipe taps that were once handy when threaded steam pipe was the thing. They allowed you to clean up threads on existing work and tie in new work withouth a demo job. They now are vitually big paperweights.

    About EMT, however, it seems is the requirement here in lots of commercial open space and in apartment houses – not just industrial facilities. Not only EMT, — we’ve done finish work on jobsites where the electricians are set up with big Greenlee hydraulic benders to install heavy walled conduit bringing 4kV or higher up risers in the building to transformer rooms and distribution panels high up in the building.
    Fire alarm circuits here are also mandated to be in conduit.

    I live in Cook County, Illinois which encompasses Chicago and a some suburbs. Here, conduit is a code requirement – even for residential use. We can use BX (or greenfield) only up to specified lengths. I can see this tool being a big time-saver even for small jobs; thanks for the post.

    these reamers do work good if u can keep ever thing working but if u ever drop them on the concret time or two the cup on the end gets bent an it is useless an the blades wear pretty fast an u cant change the screwdriver blade on the end
