Project Ideas

Business

Custom Micro-Perforated Light Cans

Offer branded lanterns and wall sconces for cafes, bars, and wedding venues by drilling logo and pattern arrays in stainless or thin steel. The bit’s split point delivers precise starts for crisp logos without laser costs.


Mason Jar Shaker Lids Line

Produce small-batch stainless shaker lids (spice, cocktail, cocoa) with clean 1/16 in arrays and sell on Etsy or wholesale to boutiques. Market on uniform hole sizing and durable, food-safe stainless finishes.


Stainless/Titanium Micro-Perf Jewelry

Create and sell lightweight earrings and pendants with perforated patterns that read as textures and gradients. Cobalt bit resists heat and wear on hard alloys, enabling consistent production runs.


Motorcycle Heat Shield Venting

Offer aesthetic/performance micro-vent patterns in stainless heat shields and guards. The bit’s ability to handle high-temp alloys and resist walking allows dense, controlled perforations that look factory-made.


Commercial Kitchen Add-On Kits

Fabricate stainless cable-clip and hook kits for kitchens and food trucks, with clean 1/16 in pilot holes for rivets/screws. Provide on-site drilling and deburring; the cobalt bit keeps cutting in tough, polished stainless surfaces.

Creative

Constellation Lantern

Micro-perforate constellations into a thin stainless steel canister or tumblers to create a star-field lantern. The 1/16 in cobalt bit’s split-point tip prevents walking on curved, slick metal, producing crisp pinholes that cast clean light patterns.


Artistic Shaker Lids

Turn mason-jar lids into spice shakers or cocktail strainers by drilling geometric or logo patterns. The bit’s stability and heat resistance keep holes uniform in stainless lids without bluing or bit drift.


Upcycled Cutlery Wind Chime

Drill small mounting holes in stainless spoons and forks to hang them on wire or rings for a bright, tinkling wind chime. The cobalt composition handles work-hardening stainless without dulling quickly.


Minimalist Metal Earrings

Cut simple discs or use stainless/titanium washers and drill clean 1/16 in holes for jump rings and dangles. The split point reduces skating on polished metal, making pairs consistent and professional-looking.


Perforated Tealight Sleeve

Wrap thin stainless or brass sheet into a small sleeve, then dot it with evenly spaced 1/16 in holes for a lace-like glow. The rigid web keeps the bit straight for tight, repeatable patterns.
