The Milwaukee 49-22-0130 Contractor's Selfeed Bit Kit is a 7-piece selfeed drill bit kit built for drilling large, clean holes in wood for pipe and conduit installation. This is a drill bit kit designed for repetitive large-diameter wood boring. Model Number: 49-22-0130. If you do rough-in work and need common selfeed sizes in one case, this kit is set up to save time instead of having you piece together sizes one by one.

Milwaukee built this set around the sizes contractors actually reach for on the job: 1 inch, 1-1/8 inch, 1-1/4 inch, 1-1/2 inch, 1-3/4 inch, 2-1/8 inch, and 2-9/16 inch. The center feed screw pilots each bit and helps pull it through the material, which reduces the amount of force needed from the user. In real work, that means less fighting the drill when boring repeated holes in clean wood framing and more consistent hole quality from start to finish.

The inside cutting plane is there for a reason. It shaves the hole radius for smooth, clean results instead of tearing through the material. That matters when you are running conduit, pipe, or other rough-in components through framing and want a predictable hole without ragged edges. Milwaukee also calls out improved balance with reduced runout, which helps the bit track cleaner and feel more controlled in the drill.

On the durability side, this kit is made for repeat use rather than one-and-done jobs. The bits are resharpenable, and Milwaukee includes two removable, replaceable feed screws. Every bit is coated with a rust inhibitor as well. If your bits live in a truck, gang box, or jobsite case, that extra protection matters more than it sounds on paper.

The included hardware makes the set more useful than a pile of loose bits. You get a 5-1/2 inch one-piece shank and coupling plus an extension for added reach in tighter spaces. Based on the product images and manufacturer details, the system uses a 7/16 inch hex shank format that fits 7/16 inch chucks and extensions, and Milwaukee shows it for use with Super Hawg, Hole Hawg, and drill products with a minimum 1/2 inch chuck size required. That gives the kit clear compatibility with heavy-duty drilling setups used in rough carpentry, plumbing, and electrical work.

The carrying case is not filler. Large selfeed bits are awkward to store and easy to damage when they roll around loose. Keeping the full set organized in one impact resistant case helps protect the cutting edges, keeps the shank and extension together, and makes it easier to bring the full range of sizes to the work area.

Who should buy this kit? Plumbers, electricians, remodelers, and general contractors doing repeated wood boring for rough-ins are the clear target. Serious DIY users can absolutely use it, but this Milwaukee selfeed bit kit makes the most sense for someone who regularly drills larger holes in clean wood and wants a ready-to-go set instead of buying individual selfeed bits as jobs come up.

Buy it once, keep it sharp, and bore big holes the right way

The Milwaukee 49-22-0130 Contractor's Selfeed Bit Kit is the kind of set that makes sense for tradespeople who drill large wood holes often enough to appreciate speed, clean cutting, and having all the common sizes in one case.

• Who it's for: Plumbers, electricians, and remodelers drilling repeated rough-in holes for pipe and conduit in wood framing.
• Why it stands out: You get the useful size spread, resharpenable selfeed bits, replaceable feed screws, and the extension and shank hardware that make the set more practical in the field.
• Worth knowing: This is not a general-purpose bit assortment. It is a purpose-built large-hole wood boring kit, so make sure your drill has at least a 1/2 inch chuck and the muscle to run selfeed bits properly.

• What material is this kit designed to cut? Milwaukee identifies these selfeed bits as ideal for clean wood.
• What chuck size do I need? The manufacturer states a minimum 1/2 in. drill chuck size is required.
• What shank size do these bits use? The bits use a 7/16 in. hex shank that fits 7/16 in. chucks and extensions.
• Can the bits be maintained instead of replaced right away? Yes. Milwaukee states the bits are resharpenable and include removable, replaceable feed screws.
