Reamer Bit - 4 in - Double-Ended #2 Phillips/#2 Robertson - 3-in-1 EMT Conduit Tool - Rack-· Tiers 72422RB

What this product is for

This 4 in (102 mm) double-ended reamer bit is made for electricians working with EMT conduit. It combines conduit reaming and driver functions in one bit to help reduce tool changes during rough-in and service work.

Use for

Use for reaming EMT after cutting, and for driving or tightening common electrical fittings with the built-in #2 Phillips and #2 Robertson ends. It is commonly used for couplings, connectors, and general electrical fastening where a quick bit change saves time.

Avoid for

Avoid using this bit as a substitute for a dedicated step bit, hole saw, or heavy-duty conduit prep tool where a specific cutting operation is required. Do not assume compatibility with every fastener style outside the listed #2 Phillips and #2 Robertson drive types.

Best for

Best for electricians and contractors who regularly install EMT and want one bit for reaming and fastening. This style is especially useful in pouch-friendly rough-in kits where fewer loose bits means faster work.

Installed in

Used with standard drill or impact driver chucks, including regular and quick-release chucks, in residential, commercial, and light industrial electrical work.

Why this product exists

After conduit is cut, the edge typically needs reaming before fittings and conductors are installed. This 3-in-1 design helps electricians ream conduit and then tighten fittings with the same bit, which can improve workflow on EMT jobs.

Compared with similar products

Compared with a standard driver bit, this tool adds conduit reaming capability. Compared with a dedicated hand reamer, it can be faster for repetitive EMT work when used in a drill or impact driver. As a rule of thumb, combination bits like this are chosen for speed and convenience rather than for every specialty cutting task.

Actual performance depends on conduit condition, tool speed, user technique, and site conditions.
