Double-ended black oxide drill bits designed for use with rotary drills and drivers. Each bit has two working tips and flutes to allow use from both ends. Intended for drilling non‑ferrous metals, sheet steel, plastics, and for making rivet or thread holes in thin‑walled materials. The bits are short and rigid for use in confined spaces and use a pointed split‑point tip to help reduce wandering and remove the need for pre‑punching in many cases.

Project Ideas

Business

Mobile Rivet and Panel Repair

Offer on-site drilling and re-riveting for gutters, signage, HVAC ducting, and auto trim. #30 (approx 0.1285 in) is ideal for 1/8-in pop rivets, and the double-ended tips reduce downtime in the field. Package services as fixed-price per panel or per linear foot.


Rivet-Ready Starter Kits

Assemble kits with #30 double-ended bits, 1/8-in rivets and backing washers, a hand riveter, clamps, safety glasses, and quick guides. Sell online, to maker spaces, and at workshops. Offer refill packs and upsell bulk bit tubes for repeat revenue.


Pop-Up Riveting Workshops

Run hands-on classes where attendees build a riveted lantern or tool caddy. Include a take-home #30 double-ended bit and materials. Monetize via ticket sales, sponsorships from tool brands, and post-class kit sales.


Drill Jigs and Templates

Design and sell CNC-cut aluminum or MDF jigs for common 1/8-in hole patterns used in van upfits, signage, and hobby aircraft skins. Bundle each jig with a #30 double-ended bit and instructions for consistent, professional results.


Fleet and Van Upfitting

Provide drilling and installation of brackets, cable clips, and paneling in service vehicles. The short, rigid bits excel in tight cavities and reduce breakage. Offer standardized packages per vehicle type and keep crews stocked with bulk packs for efficiency.

Creative

Riveted Punched-Pattern Lantern

Cut and roll thin aluminum or tin into a cylinder, then use the #30 double-ended bits to drill decorative perforations and seam holes. The split-point tip reduces wandering on curved metal, and the short length helps in tight cylindrical spaces. Rivet the seam and add a handle for a rugged, industrial lantern.


Upcycled Can Wind Chimes

Turn cans, lids, and scrap aluminum into melodic garden mobiles. Drill #30 hanging holes for wire loops and swivels; the rigid, short bits let you work inside cans without wobble. Mix metals and plastics for varied tones, then assemble with 1/8-in rivets or split rings.


Acrylic Wall Organizer

Make a modular organizer from acrylic panels. Drill clean #30 holes for 1/8-in rivets or Chicago screws to mount hooks and bins. Use low RPM, support with scrap wood, and let the split point start accurately without a punch for crisp, crack-free holes.


Riveted Metal Sketchbook

Craft notebook covers from thin aluminum or polycarbonate and add perforated artwork. Drill a row of #30 holes along the spine for 1/8-in binding posts or rivets. The double-ended bit keeps you going through multiple copies without swapping tools.


Scale Model Hardware Mounts

For RC planes, cars, or robot chassis, drill uniform #30 holes in ABS, G10, or thin aluminum to mount standoffs, harness clips, and fairings with 1/8-in rivets. The short, rigid bit improves accuracy on small parts and in confined fuselage spaces.
