Professional Features & Benefits

• 37 Total Hole Sizes: Comprehensive range from 1/8" to 1-3/8" provides versatility for diverse drilling applications across materials up to 16 gauge steel, plastic, aluminum, and wood.
• Titanium Nitride Coating: Advanced TiN coating dissipates heat effectively, extending bit life and maintaining cutting performance under demanding conditions.
• Dual Spiral Fluting: Two spiral flutes on each bit efficiently remove chips and help pull the bit through material for faster, cleaner cutting action.
• High Speed Steel Construction: Durable material provides reliable performance and longevity for professional and heavy-duty applications.
• 1/4" Hex Shank: Universal hex shank design ensures firm, positive grip in both impact drivers and standard drill chucks.
• Split Point Tip Design: Precision tip quickly starts hole cuts and prevents drifting when pressure is applied, ensuring accurate hole placement.
• Complete Kit with Case: Rugged protective case with custom inserts keeps bits organized and includes 1-ounce oil bottle for proper lubrication and maintenance.
