Skil 115 Piece Drilling and Driving Bit Kit

First impressions and setup

A compact, all-in-one bit kit can save a lot of trips back to the toolbox. That’s exactly why I picked up the Skil bit kit: 115 pieces in a case that fits in one hand, with drilling and driving covered for wood, metal, plastic, and light masonry. Out of the box, the assortment is broad and logical—common insert bits in both 1-inch and 2-inch lengths, a 3-inch magnetic bit holder, nut setters, standard HSS twist drills, and a handful of masonry bits. There are also some screws for test drives, which is a small touch but useful if you just want to verify setup before starting a job.

The case is 8.7 x 7.7 x 2 inches and around 2.4 pounds loaded, so it’s easy to toss into a tool bag. The trays keep things secure, though a few of the slots hold bits so tightly that removing them one-handed is tough. That’s a minor annoyance at the bench, more noticeable if you’re on a ladder.

What’s in the kit, and what’s not

• 43 × 1-inch insert bits and 18 × 2-inch insert bits cover Phillips, slotted, Torx, square, and a few less common profiles. The basics are well represented, and the 2-inch lengths are especially handy for reaching past hardware and getting out of recessed pockets.
• 8 × nut setters span common hex fastener sizes. For furniture assembly, metal brackets, and HVAC screws, these cover most needs.
• 10 × HSS drill bits handle general-purpose drilling in wood, plastics, and mild steel.
• 5 × masonry bits are intended for brick, mortar, and block in light-duty applications. Not for hammer-drill SDS use.
• 1 × 3-inch magnetic bit holder gives you extra reach.
• A Magnetic Bit Grip collar boosts screw retention when used with 2-inch bits—more on this below.

There are no spade or brad-point wood bits, no step bits, and no specialty metal cutters (like cobalt or titanium-coated). That’s fine for a generalist kit at this price point, but it’s worth knowing where the boundaries are.

Build quality and organization

Skil’s organization is sensible: drivers and drills are grouped, sizes are labeled, and the bit profiles are easy to spot. The case is compact and latches securely, but it’s not contractor-grade; the hinge is standard molded plastic, and I wouldn’t expect it to handle years of daily jobsite abuse. For homeowners and light trade use, it’s perfectly serviceable.

Bit retention is a trade-off: the holders grip firmly, which prevents spills. On the other hand, several of the driver bits—especially the 1-inch inserts—sit so tight you need a fingernail or a small pick to extract them quickly. After a few in-and-outs, they loosen slightly, but it’s still tighter than I prefer.

Driving performance

The driver bits are the backbone of this kit, and they hold up well for general work. In plywood cabinets and SPF framing, the Phillips and Torx bits seated fasteners cleanly with minimal cam-out when paired with an impact driver set to moderate torque. The 2-inch bits are where the kit shines: the extra length gives better visibility, and when you slide on the Magnetic Bit Grip collar, screw starts become much more controlled.

That collar is genuinely useful. It’s essentially a magnetic sleeve that fits over a 2-inch bit, increasing magnetic pull and guiding the screw. I used it for overhead work and blind starts in tight corners; it kept screws from wandering and allowed one-handed starts where otherwise I’d have needed a second hand to steady the screw. The included 3-inch magnetic holder is fine for general reach, though the magnet isn’t the strongest I’ve used. For long or heavy structural screws, I still prefer a dedicated impact-rated holder with a deeper cup, but for cabinetry, brackets, outlet covers, and hardware, this one is adequate.

Nut setters are solid for hex-head screws in light-gauge metal and hangers. They’re not labeled as impact-rated, so I kept my impact driver on a lower setting. No issues with rounding or looseness in typical use.

Drilling in wood, metal, and plastic

The HSS drill bits are basic but competent. In pine and poplar, they cut cleanly with minimal tear-out when I piloted first and stepped up sizes. In hardwood (oak and maple), results were fine as long as I paid attention to speed and backed the bit out to clear chips. They’re standard point geometry, so they walk a touch on slick surfaces without a punch mark, but nothing out of the ordinary.

In plastics (ABS and acrylic), slow speed and light pressure produced clean holes without melting. For repeated holes in brittle plastics, I’d still reach for brad-point or specialized plastic bits, but the included HSS pieces handled one-off tasks without trouble.

On mild steel flat bar and thin sheet, the bits worked as expected for HSS. A drop of cutting oil, slower RPM, and pecking to manage heat kept the edges sharp across a handful of holes. These are not cobalt or heavy-duty split-point bits, so I wouldn’t use them for thick stainless or hardened steel. If metal is your main workload, plan on upgrading that part of your kit.

Light masonry work

The five masonry bits are serviceable for anchors in brick, block, and mortar. Using a standard drill on hammer mode, I set plastic anchors for brackets and conduit clamps without drama. They’re not meant for poured concrete or aggregate-heavy slabs, and they’re certainly not SDS or intended for full-time masonry work. Think occasional household tasks and you’ll be in the right lane.

Durability notes

After several weekend projects—assembling shelves, installing hardware, mounting a hose reel and a TV bracket, and some light metal drilling—the driver bits show normal wear but no chipped tips. The smaller HSS drills dull faster if pushed hard in metal; used with lube and sane speeds, they last fine for DIY pace. The case has held up to being tossed in the back of a hatchback and stacked under a drill; the latch still snaps tight, though I wouldn’t sit on it.

Ergonomics and workflow

• Bit access: Secure but sometimes too tight. Plan on two hands for a few of the trays.
• Labeling: Easy to read on the case; size stamps on the tiny drill bits are small (as usual) but present.
• Magnetic aids: The Bit Grip collar is a real convenience, especially with the 2-inch bits. The 3-inch holder is a decent general extender.

Value and alternatives

As a “get-most-things-done” kit, this lands in a sweet spot. You could piece together higher-end components—impact-rated drivers, cobalt drills, premium masonry bits—but you’ll spend more and lose the convenience of a single, organized case. Compared with sets from premium brands, this Skil kit offers a broader assortment for the money, with sensible compromises: basic HSS instead of cobalt, standard masonry instead of SDS, and a mid-tier case.

If you’re a pro who drills metal all day or sets hundreds of Tapcons a week, you’ll outgrow the included drills quickly and want dedicated bits. For homeowners and light-duty trade users, this is the kind of kit that lives in the drill case and solves 90% of everyday tasks.

Who it’s for

• Homeowners, renters, and DIYers who want an all-in-one drilling and driving set for wood, plastic, mild steel, and light masonry.
• Light trade users who need a backup or jobsite beater kit with wide coverage.
• Anyone who appreciates a compact, organized case that’s easy to grab and go.

Who should look elsewhere:
- Users drilling lots of stainless or thick steel (consider cobalt or M42 sets).
- Heavy masonry users (consider SDS-plus systems and carbide masonry sets).
- Those who are hard on cases—if you break boxes often, you’ll want a more rugged organizer.

Recommendation

I recommend the Skil bit kit as an affordable, well-rounded set for general-purpose drilling and driving. It covers the essentials with a thoughtful mix of 1-inch and 2-inch drivers, useful nut setters, a legitimately helpful magnetic collar, and enough drill bits to handle common wood, plastic, mild steel, and light masonry tasks. The trade-offs are reasonable: basic HSS instead of specialty metal bits, a case that’s more homeowner than jobsite-tough, and bit trays that grip a little too firmly. For most users, the convenience and breadth of the assortment outweigh those nitpicks. If you’re building out a first kit or want a compact “do-most-things” companion to your drill and impact driver, this is a smart buy.
