You get better bite with less chance of rounding stubborn fasteners.PACKOUT Drawer ReadyThis Milwaukee metric ratcheting combination wrench set includes a reinforced tray with high-contrast EVA foam sized for PACKOUT drawer tool boxes. It keeps every wrench visible, protected, and easy to grab.
Overview
The Milwaukee 48-22-0156 15-Piece Metric Ratcheting Combination Wrench Set with Tray for PACKOUT Drawers is a metric ratcheting combination wrench set built for mechanics, technicians, and tradespeople who want faster access to fasteners and cleaner organization in a drawer system. This is a ratcheting combination wrench set designed for tightening and loosening metric nuts and bolts in tight spaces. Model Number: 48-22-0156.
What makes this set matter on the job is how it balances access, torque, and storage. Milwaukee rates the ratcheting end at 2.5 degrees of arc swing with 144 ratcheting positions, which means less handle movement between clicks. In real use, that helps when you are working around engine components, hydraulic lines, machine guards, and packed assemblies where there is no room to swing a standard wrench very far.
The open end is not just there as a backup. Milwaukee’s MAX BITE open-end grip is designed to hold fasteners more securely and deliver up to 25% more torque while reducing rounding and stripping. If you spend time breaking loose rusty hardware or snugging down fittings without damaging the flats, that geometry is a real advantage over a basic smooth-jaw wrench profile.
The wrenches themselves are built around an I-beam handle design for comfort during high-torque work. That shape gives your hand a more secure feel without making the wrench bulky. Milwaukee also uses ink-filled size markings, which sounds simple, but it saves time when you are reaching into a drawer and need the right size quickly instead of flipping tools over to read a faint stamp.
This set is also about organization, not just the wrenches. The reinforced tray uses high-contrast EVA foam so every tool has a dedicated spot and missing sizes stand out fast. For mobile setups and service carts, that is a big deal. You can tell at a glance whether the 10 mm walked off before you leave the jobsite or close up the truck for the night.
Compatibility is a key reason to buy this version instead of a loose wrench set. The tray is designed for Milwaukee PACKOUT Drawer Tool Boxes, including models 48-22-8444, 48-22-8442, and 48-22-8447. If you already run PACKOUT for service, electrical, mechanical, or shop organization, this lets your wrench storage match the rest of the system instead of dropping a generic tray into a premium box.
Material matters here too. Milwaukee lists chrome vanadium steel for the wrenches, with foam and polypropylene in the tray assembly. The chrome-plated finish helps with rust protection, which is worth paying attention to if these tools live in a van, trailer, or unconditioned shop where moisture and grime are part of the deal.
Who should buy it? If you are an automotive tech, diesel mechanic, maintenance pro, industrial technician, or serious DIYer who works on metric hardware regularly, this set makes sense. You get the core metric sizes from 8 mm through 22 mm, a ratcheting box end for speed, a stronger-gripping open end for control, and a storage format that actually fits an organized PACKOUT drawer setup.
Work Faster in Tight Engine Bays and Equipment Compartments
The reason to buy a ratcheting combination wrench set instead of a basic wrench set is simple: less repositioning, less wasted motion, and better access when space is limited. This set is made for real service work where hoses, brackets, and surrounding components get in the way.
- 2.5° arc swing helps turn fasteners with minimal handle movement
- 144 ratcheting positions improve control in confined working areas
Keep Every Size Organized in Your Drawer System
A good wrench set is only as useful as the time it takes to find the right one. Milwaukee built this version around a reinforced tray and high-contrast foam so the set drops into compatible PACKOUT drawers and keeps size identification quick and obvious.
- Includes dedicated positions for 15 metric wrenches from 8 mm to 22 mm
- High-contrast EVA foam makes missing tools easy to spot fast

Pro Tip
If you run PACKOUT drawers in a truck or rolling stack, keep each wrench in its assigned foam slot after every job instead of tossing them back loose. On a 15-piece metric set, the missing size usually shows up as a problem when you need it most, and the high-contrast tray makes that obvious before you leave.
