Key Features

Tight-Access Ratchet

The 90-tooth ratchet gives you a 4 degree arc swing, so you can keep turning fasteners where a standard ratchet runs out of room.

Four Flat Sides

Milwaukee’s FOUR FLAT socket design helps stop sockets from rolling off benches and also gives you wrench-ready flats when you need another way to turn them.

56-Piece Coverage

This Milwaukee ratchet and socket set covers both SAE and metric sizes, with standard and deep well sockets, extensions, a universal joint, and a case that keeps the whole set together.

Overview

The Milwaukee 48-22-9008 3/8 in. Drive SAE and Metric Ratchet and Socket Set is a 56-piece hand tool set built for mechanical work, equipment service, and general fastening jobs where you need a compact ratchet and a broad socket spread in one case. This is a ratchet and socket set designed for tightening and loosening SAE and metric fasteners in automotive, shop, and jobsite work. Model Number: 48-22-9008.

What matters here is not just the piece count. Milwaukee built this set around a 90-tooth ratchet with a 4 degree arc swing, which makes a real difference when you are working around engine bays, machinery, brackets, or packed utility spaces. Instead of needing a big handle reset between clicks, you can keep moving in tighter spots and stay productive.

The sockets are the other big story. Milwaukee’s FOUR FLAT sides are there for a reason. They help keep sockets from rolling away when they are sitting on a fender, cart, or bench, and they also give you wrench-ready flats for added utility. That is a practical upgrade over fully rounded sockets, especially if you work out of a service truck, a garage, or anywhere dropped tools cost time.

This set includes both standard and deep well sockets in SAE and metric sizes, plus a 3 inch extension, 6 inch extension, universal joint, and the ratchet itself. That gives you useful coverage for mixed fastener platforms without forcing you to jump between multiple small sets. For techs and serious DIY users, having standard and deep well options in the same case is what makes a set like this actually useful day to day.

Milwaukee also paid attention to readability and storage. The sockets use laser engraved size markings for easier identification, which matters when you are moving quickly or working in less-than-ideal lighting. The set comes in a portable carrying case, and the removable inner tray is designed so you can drop it into a steel storage chest for long-term organization instead of always carrying the full case.

Material matters in hand tools, and this set uses chrome vanadium steel with chrome-plated rust protection. That combination is what most buyers want in a working ratchet and socket set because it balances strength, corrosion resistance, and easy cleanup after shop use. The slim-profile ratchet head and flush directional lever also help the tool fit where bulkier ratchets start getting in the way.

If you work on vehicles, equipment, maintenance tasks, or general assembly and service jobs, this set makes sense. It is especially well suited for automotive techs, maintenance crews, contractors who keep a mechanics set on the truck, and home garage users who are tired of piecing together mismatched sockets. If you want one 3/8 inch drive socket set that covers a lot of common fastener sizes and works well in confined spaces, this Milwaukee set is aimed right at that buyer.

Better Access in Tight Spaces

This is where the ratchet earns its keep. The fine-tooth mechanism and slim head help you turn fasteners where hoses, panels, and surrounding parts limit your swing.

• 90-tooth ratchet design
• 4 degree arc swing for confined work areas
• Slim profile head with flush directional lever

Sockets That Stay Put and Read Fast

Milwaukee did not treat the sockets like an afterthought. The flat-sided design helps stop roll-off, while the engraved markings make size checks quicker when you are working through a long list of fasteners.

• FOUR FLAT sides help deter rolling
• Wrench-ready socket design adds versatility
• Laser engraved markings improve identification

Tool Nut’s Take

Tool Nut’s Take

Milwaukee 48-22-9008 3/8 in. Drive SAE and Metric Ratchet and Socket Set Gets the Basics Right

This is the kind of 3/8 inch drive socket set that makes sense for real service work because it covers the common sizes, works in tight spots, and stores well.

• Who it’s for: Automotive techs, maintenance crews, contractors, and home garage users who want one solid SAE and metric ratchet socket set instead of a pile of loose pieces.
• Why it stands out: The 90-tooth ratchet, 4 degree arc swing, FOUR FLAT anti-roll sockets, and removable storage tray are all practical features you notice when the job gets cramped or messy.
• Worth knowing: This is a 3/8 inch drive focused set, so it is a great middle-ground mechanics kit, but you will still want other drive sizes for very small or very high-torque work.
