Bosch Custom Case System Mixed Drill Bit Clips Review
A compact bit set that actually earns its spot in the bag
I’m picky about what gets to live in my everyday drill/driver bag. Space is tight, and I only keep kits that pull their weight across a week of mixed tasks. The Bosch bit clip set (the 8-piece mixed driver and drill kit) made the cut after a few projects where I needed to travel light but still be prepared for basic drilling and driving. It’s a small, focused assortment that pairs nicely with a drill/driver or impact driver, with a case design that’s more helpful than it looks at first glance.
What’s in the set
You get five driver bits—two PH2, one Robertson R2 (Square #2), and Torx T20 and T25—and three black oxide drill bits in 1/8", 3/16", and 1/4". All pieces use a hex shank for easy changes and compatibility with both three-jaw chucks and hex chuck drivers.
That selection is very intentional. PH2, R2, T20 and T25 cover a huge swath of modern cabinet hardware, furniture fasteners, decking screws, and general construction screws. The drill sizes are your bread-and-butter pilots for typical #8/#10 screws, clearance holes, and light bracket mounting.
If you work in environments that lean heavily on Pozidriv (PZ) or oddball fasteners, this set won’t do everything. But as a compact, grab-and-go clip, it hits the most common fasteners I see in residential work.
Case and organization
Bosch’s Custom Case System is one of the better modular ecosystems going, and this clip is designed to snap into that setup. On its own, the included mini-case feels sturdy, with rubber bumpers and a latch that doesn’t pop open in a tool bag. The tilt-in/tilt-out rails sound like a gimmick, but the access is genuinely smoother than fighting a stiff bit strip. One-handed retrieval is easy, and the bits don’t fling out if the box gets knocked around.
Two nice touches:
- The latch is secure but not fussy—glove-friendly and predictable.
- The clip integrates neatly with larger Bosch cases, so I can rearrange this set next to spade bits or nut drivers depending on the day’s tasks.
If I had a nit, it’s that the tilt-in mechanism can feel tight the first few uses, but it breaks in and then just works. There’s no wasted space, and nothing rattles loose.
Driving performance
The driver bits are impact-rated, with a visible torsion zone designed to absorb torque peaks. In practice, that matters. I ran PH2 and Torx screws with an 18V impact driver into studs and plywood cabinet sides. Engagement was positive, and I had fewer cam-out moments than I expect from generic bits. The torsion section takes the sting off abrupt stalls and reduces that chattery feel you get when a bit is about to slip.
The R2 bit is a welcome inclusion. Square fasteners show up in plenty of stock shelving kits and electrical boxes, and it’s frustrating to be caught without it. The T20 and T25 bits have crisp machining and seated cleanly in decking and cabinet hardware screws.
After a week’s worth of tasks—mounting closet shelf standards, assembling flat-pack furniture, and resetting a few cabinet pulls—the tips showed minimal rounding and still held fasteners without wobble. I haven’t found a reason to baby these; they tolerate impact use as advertised.
Drilling performance
The three black oxide drill bits are general-purpose, not specialty pieces. I used them primarily in a drill/driver (not an impact) for pilots and clearance holes in pine studs, MDF shelving, and laminated particleboard.
Observations:
- The 1/8" and 3/16" bits cut clean pilots with predictable feed and didn’t burn when run at sensible speeds.
- The 1/4" bit tracks straight in wood but, like many general-purpose bits, benefits from a quick awl mark or punch to prevent walking on slick laminates.
- Chip evacuation is fine for shallow holes. For deeper goes in resinous lumber, back out occasionally to clear chips and keep heat down.
- In thin mild steel, the 1/8" and 3/16" bits will make holes if you use cutting fluid and moderate pressure. That said, black oxide isn’t a miracle coating—if you’re drilling metal all day, reach for cobalt or TiN-coated jobber bits. Consider these a convenience for occasional metal, not a dedicated solution.
The hex shanks make changes quick and prevent chuck slip, which is great when you’re bouncing between drilling pilots and driving screws without a second tool at hand.
Ergonomics and workflow
This kit suits a lean workflow. I like to clip it into a larger Bosch case when I’m carrying a broader assortment, but on quick jobs I’ll throw this standalone clip into a pocket of my tool bag and be done. The ability to tilt a bit out with one hand and snap it back without fuss seems minor until you’re on a ladder managing hardware with the other hand.
One more workflow win: having both pilots and drivers together cut down on fussy reconfigurations. I drilled a 3/16" pilot, popped in a T25, and ran cabinet rail screws in sequence without hunting around.
Durability so far
Driver bits: excellent for their class. The torsion zone seems to be doing its job; no fractures, and the tips still bite crisps screws. I’ve abused the PH2 a bit with structural screws and it’s hanging in there better than non-impact bits I’ve used.
Drill bits: holding an edge in wood after a normal workload. Black oxide won’t outlast premium coatings in abrasive materials, but for wood, MDF, and occasional plastic, they’ve kept their edge. No flutes bent, no hex-shank twisting—always a good sign.
Case: the rubber bumpers shrug off drops, and the latch hasn’t sprung open in the bag. The internal rails retain bits firmly but don’t require fingernail acrobatics to release them.
Where it falls short
- Limited drill sizes. Three sizes cover many pilots, but if you need frequent 5/32" or 7/32" pilots, you’ll want a supplemental clip.
- No magnetic bit holder or sleeve in the box. If you rely on a magnetic extension for reaching into cabinets or providing additional stability, bring your own.
- Not a masonry or metal specialist. Keep expectations reasonable: this is a general mixed set, not a comprehensive drilling solution for steel or concrete.
- Euro users might miss PZ bits. The selection is tailored for North American fastener habits.
None of these are deal-breakers for what the kit is intended to be: a compact, high-utility add-on.
Who it’s for
- DIYers and homeowners who want a reliable, small kit that covers the most common screws and pilot holes for mounting shelves, hardware, and fixtures.
- Pros who already run Bosch’s Custom Case System and want a tidy clip they can reconfigure alongside other bit sets.
- Anyone who prefers impact-rated driver bits that last, but doesn’t need a massive assortment.
If you’re outfitting a full-service bit drawer from scratch or drilling metal daily, you’ll want a larger, specialized set to complement this one.
Tips for best results
- Use the driver bits with an impact driver for tough fasteners; that torsion zone earns its keep under high torque.
- Drill pilots in wood at moderate speed to avoid heat glazing, especially in MDF.
- Mark laminates and painted surfaces with an awl before using the 1/4" bit to prevent walking.
- Keep a magnetic bit holder in your bag; it pairs well with this kit but isn’t included.
The bottom line
The Bosch bit clip set doesn’t try to be everything. It aims to cover the work you most often encounter when installing shelves, assembling furniture, mounting brackets, or swapping cabinet hardware—and it succeeds. The impact-rated driver bits grip well and hold up under real torque. The black oxide drill bits handle common pilots cleanly in wood and engineered panels. The case is compact, robust, and genuinely convenient to use, whether riding solo or clipped into the broader Custom Case System.
Recommendation: I recommend this set as a compact, go-to clip for everyday drilling and driving in wood and light materials. It’s a smart addition to a drill/driver bag, particularly if you value impact-rated driver bits and a case that won’t fight you on access. Pair it with a larger drill index if you need more sizes or specialty materials, but as a daily carry for common tasks, it’s a solid, reliable choice.

French-Cleat Wall with Docked Bit Case
Build a modular French-cleat wall for your shop and mount a short cleat-adapter that accepts the Custom Case System clip so the bit case can ride the wall beside your drill. Use the 1/8 in bit for pilot holes in studs, 3/16 in for clearance holes, and PH2/T20/T25/R2 driver bits to hang bins, tool holders, and shelves without cam-out. The tilt-in/tilt-out case keeps swaps quick while you layout and rearrange fixtures.
Upcycled Pallet Planter Boxes
Break down pallets and build rustic planter boxes with reinforced corners. Predrill with 1/8 in for screws to avoid splitting, use 1/4 in for drainage holes, and drive Torx or Robertson deck screws with the T20/T25 or R2 bits for strong outdoor joints. The black oxide drill bits handle abrasive pallet wood better, and the clipped case keeps bits accessible as you move along a long assembly line.
Geometric Screw-Mosaic Wall Art
Create a low-poly or gradient artwork using screws set to varying depths for texture. Lay out a pattern on plywood, predrill with 1/8 in, then drive PH2 or R2 screws to mapped depths. Finish with stain or paint over the screw heads for a striking effect. The torsion-zone driver bits reduce cam-out when setting precise depths, and the case lets you quickly swap between bit types for different head styles.
Portable Camping Chuck Box
Build a compact camp kitchen box with shelves, fold-down work surface, and utensil hangers. Use 3/16 in clearance holes for hardware, 1/8 in pilots for hinges and latches, and T20/T25 bits for exterior screws. Mount a short CCS rail inside the door so the bit case clips in for field repairs and accessory add-ons. Rubber-bumpered case handles bumps during transport.
Drill/Driver Docking Caddy
Make a bench-top caddy that stores your drill, driver, battery charger, and fasteners.
