1/8"–1/2" Step Drill Bit – The Biter’s Best Friend
Simple. Tough. Effective. This high-speed steel (HSS) step drill bit is the go-to starter for anyone using the Bad Dog Biter. Designed to drill clean, precise starter holes from 1/8" to 1/2", it punches through the same sheet materials your Biter was born to chew up.
Whether you’re cutting out custom dash panels, fabricating HVAC ducts, or starting a clean plunge in aluminum, steel, or plastic—this bit gets you in clean and keeps you moving.
✅ HSS Construction – Tough enough for metal, fast enough for clean entry
✅ Step Range: 1/8" to 1/2" – One bit, multiple hole sizes
✅ Perfect Biter Companion – Drills clean starter holes in center of sheet
✅ Works on Steel, Aluminum, Plastic & More – Versatile, no-fuss performance

Use it before the Biter. Use it on its own. Either way, it’s the perfect addition to your metalworking setup—especially when you want clean, centered holes without switching bits every five seconds.
