Tin Punch Lanterns
Cut and roll thin galvanized sheet or upcycled tin cans into lanterns, then fasten seams and hangers with small P1 Phillips self-tapping screws. The extra-hard S2 bit grips tiny case-hardened screws without cam-out, letting you assemble cleanly after punch-patterning the light holes.
Metal-and-Wood Herb Planter Rail
Build a wall-mounted rail with a wood backer and aluminum flashing liners. Use small P1 self-drilling screws to attach folded liners to the wood frame and to install hanging brackets. The reinforced bit handles the hardened screws going through thin metal without stripping.
Compact Sheet-Metal Toolbox
Form a lightweight toolbox from 26–28 ga sheet metal (bent on a simple brake or clamped boards). Join corners, hinge, and latch tabs with #4–#6 self-tapping screws driven by the P1 bit. The 1-inch insert fits tight spaces and keeps the tiny screws seated securely.
License Plate Birdhouse
Craft a wooden birdhouse and clad the roof and entry trim with old license plates. Use small case-hardened sheet metal screws to attach plates to the wood and to each other. The hardened, precision tip reduces wobble on the slick painted surface.
Magnetic Pegboard Spice Rack
Mount a perforated steel sheet to a wood board using #4–#6 self-tapping screws, then use magnetic spice tins on the panel. The bit’s reinforced design helps drive into metal without rounding the small screw heads, keeping the panel flat and rattle-free.
