The Milwaukee 48-22-6316 16 in. Straight-Jaw Pliers are a heavy-duty hand tool for gripping, turning, and working larger pipe and irregular material. This is a straight-jaw pliers tool designed for pipe gripping, pipe reaming, and electrical knockout work. Model Number: 48-22-6316. If you want one pair of tongue and groove pliers that can handle bigger capacity and still do more than just clamp, this is the one Milwaukee built for that job.

The biggest reason this tool matters is capacity. Milwaukee rates the jaw for up to 4-1/4 inch round pipe, which gives these pliers more reach on plumbing, mechanical, and general service work where smaller groove pliers run out of adjustment. The hardened teeth are there for a reason too: they keep bite over time, so the tool stays useful instead of turning into a smooth-jaw nuisance after repeated use on pipe and fittings.

What separates these from a basic pair of straight-jaw pliers is the REAM & PUNCH handle design. The exposed metal handles are made to deburr smooth pipe up to 3 inches and punch electrical knockouts. That saves a trip back to the bag for another tool when you are roughing in or cleaning up pipe ends before assembly. Milwaukee also uses a precision-ground pliers head, which helps the jaws seat cleanly on the work instead of feeling sloppy.

For day-to-day handling, Milwaukee uses slim over-molded comfort grips that are built not to peel under jobsite conditions. That sounds like a small detail until you have used pliers with grips that start rolling, tearing, or sliding after heat, cold, dirt, and oil. The forged design adds strength, and the rust-resistant finish helps when the tool sees wet work, service vans, or outdoor storage.

At 16 inches long, these are not meant to replace your compact pliers for tight cabinet work. They are meant for jobs where leverage, jaw opening, and grip matter more. That longer handle length gives you better control and more turning power on stubborn fittings, larger pipe, and material that takes more than fingertip pressure to hold. If you are dealing with bigger plumbing connections or mechanical installs, that extra size pays off fast.

The Milwaukee 48-22-6316 16 in. Straight-Jaw Pliers make the most sense for plumbers, HVAC techs, electricians, maintenance crews, and general contractors who want one durable pair of large straight-jaw pliers that can grip hard, ream pipe, and take daily abuse. If your work regularly involves larger pipe, knockouts, or rough service conditions, these are worth the space in the bag. If all you need is a compact pair for light-duty fastening, this is more tool than you need.
