KingTool Drilling and Driving Accessory Kit

Why I reached for this kit

I’m a sucker for compact, do‑most‑things kits, especially when I’m bouncing between small home projects that don’t merit hauling multiple cases. This 318‑piece KingTool kit promised a lot on paper: HSS twist drills, wood and masonry bits, a mountain of driver bits, and a handful of Allen keys, all in a single, molded case. After a few months of mixed use—hanging shelves, swapping door hardware, assembling furniture, and drilling a handful of holes in brick—I’ve got a pretty clear picture of where it shines and where it doesn’t.

What’s inside and first impressions

The assortment is genuinely broad. You get:

• HSS twist drills for metal and general work
• Wood bits (brad‑point style in my set)
• Masonry bits for brick, block, and light concrete
• A deep selection of driver bits in common profiles (Phillips, slotted, Torx, square, hex)
• A magnetic bit holder and a few nut drivers
• Allen wrenches

Most of the driver bits are Cr‑V steel and the drills are HSS. Each piece is coded for quick identification; that small touch makes a difference when you’re in the middle of a task and don’t want to squint at shank engravings.

The case is better than I expected for the price. It’s a molded plastic shell that’s reasonably stiff, dirt resistant, and compact (about 11.8 x 8.8 x 2 inches). At just under 6 pounds, it’s grab‑and‑go without feeling flimsy. The latches close positively and the hinge hasn’t shown any slop yet.

A quick tip from experience: keep the plastic insert and the thin foam pad that ships in the lid. If you toss them, some of the smaller bits will migrate when you carry the case upright. With both in place and the case opened “right‑side up,” everything stays where it should.

Drilling performance

• Wood: The brad‑point wood bits track straight and produce clean exit holes in softwood and plywood. In maple and oak, they did fine for pilot holes up to about 3/16 inch; beyond that, I slowed the speed and backed the bit out to clear chips. Edge blow‑out was minimal when I clamped a sacrificial backer.

• Metal: The HSS bits are a solid “general duty” option. I ran 1/8 and 3/16 inch holes through 1/8 inch mild steel angle with a dab of cutting oil at moderate RPM and had no drama—nice curls, no blueing. When I pushed larger diameters without stepping up, heat built quickly and the cutting edges lost their bite faster, which is normal for value‑oriented HSS. For stainless or repeated heavy steel work, I’d reach for M35/M42 cobalt bits instead.

• Masonry: In brick and mortar, the masonry bits paired with a hammer drill performed adequately. I drilled a series of 1/4 inch holes for anchors and they kept their carbide edges long enough to finish the run cleanly. In cured, aggregate‑heavy concrete they dulled faster; that’s the point where SDS‑plus bits and a rotary hammer are the better choice.

One small usability note: the coding on the shanks helps you grab the right family of bits quickly, and the sizing progression is sensible. I didn’t have any odd gaps that forced me to jump too far between sizes.

Driving performance

The driver assortment is the star here. You get a healthy supply of the profiles you actually use—lots of PH2, T15, T20, and a mix of slotted, square, and hex. The Cr‑V bits are reasonably hard and resist twisting in general DIY tasks. I drove deck screws into SPF studs, mounted cabinet hardware, and assembled a couple of flat‑pack pieces without early cam‑out.

That said, there are limits. Running long #2 Phillips screws into pressure‑treated lumber with an impact driver will find those limits quickly. I noticed rounding at the tip of a PH2 after a few dozen aggressive drives. Switching to Torx for heavy work extended bit life considerably. The included bit holder’s magnet is strong enough, but the detent isn’t as authoritative as my dedicated holders; it never failed, but it doesn’t have that locked‑in feel you get with premium accessories.

If you’re a pro driving hundreds of fasteners a week, you’ll want S2 steel impact‑rated bits for durability. For weekend projects and general maintenance, the included bits are perfectly serviceable.

Case and organization

Organization is a genuine strong point. The molded trays keep families of bits together, the coding reduces rummaging, and the compact footprint means I can toss it in a backpack or tool bag. After a few trips rolling around in a truck, the case still closes evenly and the hinges are intact. Again, keep the foam and be mindful of orientation when you open it; do that and you won’t be re‑sorting pieces on the floor.

Durability and maintenance tips

Longevity with any bit set depends on technique. A few habits that paid off with this kit:

• Use a clutch setting when driving to reduce cam‑out and tip rounding.
• For metal, drop the RPM and use cutting oil; step up hole sizes rather than forcing a large bit.
• Let bits cool between holes—overheating kills edges.
• In masonry, use hammer mode and don’t exceed what a small carbide tip can reasonably handle.
• Keep bits clean and dry; the steel resists corrosion, but grit and moisture still take a toll.

Following those basics, my most‑used pieces (PH2, T20, 1/8 inch HSS, and 3/16 inch masonry) are still in rotation and cutting cleanly.

What could be better

• Driver bit metallurgy: For heavy duty or impact‑intensive tasks, the bits show wear sooner than premium, impact‑rated options. More S2 steel in the mix would elevate the set.
• Bit holder: It works, but the retention could be more positive. I swapped to my usual quick‑change holder for most driving.
• Case retention: Some smaller pieces will wander if you discard the foam or open the case upside‑down. It’s manageable, but worth noting.

None of these are dealbreakers in a budget‑friendly, all‑in‑one set, but they’re the tradeoffs that separate it from pricier pro kits.

Who it’s for

• Homeowners who want a single case that covers 90% of common tasks—assembling furniture, hanging shelves and blinds, swapping hardware, light metal work, and occasional masonry.
• DIYers who value variety and organization over boutique metallurgy.
• Anyone who wants a portable “grab it and go” companion to a drill/driver.

Who should look elsewhere: tradespeople who drive fasteners all day, anyone drilling a lot of stainless or thick steel, and those doing frequent concrete anchoring. Specialized, higher‑grade bits pay off in those scenarios.

The bottom line

The KingTool kit earns a permanent spot near my drill and impact. It’s compact, thoughtfully organized, and packed with the bits I actually reach for. The HSS and masonry drills handle light to moderate tasks reliably when used with sane technique, and the driver assortment is extensive enough that I rarely come up empty. The case holds up, the coding is genuinely helpful, and the overall package punches above its price.

I’d recommend this kit to homeowners and DIYers who want an all‑in‑one, portable solution at a sensible cost. It’s not a replacement for pro‑grade, impact‑rated bits or cobalt drills in demanding work, but as a versatile, everyday companion, it offers strong value and saves time hunting for the right piece. Keep the foam, use the right speed and pressure, and this kit will cover a surprising amount of ground without drama.
