Chickadee/Wren Birdhouse
Build birdhouses with species-correct 1-1/8 in entrance holes for chickadees and wrens. The self-feeding tip pulls cleanly through softwoods like cedar; clamp a backer to avoid blowout. Add a hinged clean-out, sloped roof, and drain holes for a polished backyard wildlife project.
Glass Tube Propagation Station
Make a minimalist stand that suspends 25–28 mm glass tubes for plant cuttings. Drill evenly spaced 1-1/8 in through-holes in a hardwood bar and press in rubber grommets to grip the tubes. The aggressive spur keeps holes true even when drilling at slight angles for a cascading look.
Modern Peg Rack with 1" Dowels
Create a coat/hat rack by drilling 1-1/8 in angled pass-through holes in a board and inserting 1 in hardwood dowels as pegs. The extra 1/8 in of clearance allows for glue and epoxy; the bit’s self-feed makes consistent angle drilling easier with a simple wedge jig.
Industrial Copper-Pipe Lamp Base
Route 3/4 in copper pipe (0.875 in OD) through a wooden base by drilling 1-1/8 in holes for clearance. Hide wiring inside the pipe for a clean industrial lamp. The open-tooth design is easy to touch up between hardwood bores to keep edges crisp.
Cornhole Board Carry Handles
Add carry handles to cornhole boards by drilling two adjacent 1-1/8 in holes and connecting them with a jigsaw to form a slot. The quick-change shank speeds up repetitive drilling across multiple boards; round over the edges for comfort.
