DEWALT Drill Bit Set, 3-Flats Shank, 14-Piece
The DEWALT DWA1184 set features a 135-degree split point designed to reduce walking on softwoods, plastics, and metals. Made from high-speed steel, these bits provide a versatile option for common drilling tasks, while the 3-flats shank offers a secure grip in power tools. The tapered web improves durability and resistance to breakage, ideal for members who demand reliability on the job site.
DEWALT Titanium Nitride Coated Drill Bit Set, Pilot Point, 21-Piece
This 21-piece set from DEWALT uses a titanium nitride coating and a pilot point to start cleanly, reducing walking and extending bit life. The no-spin shanks help minimize wobble during initial contact, delivering cleaner holes in a variety of materials.
Viking Drill & Tool 44150 SP-29 29-Piece Set
The Viking SP-29 set provides a comprehensive 29-piece collection with a 135-degree split point for accurate starts. Precision-ground points and tailored flute geometry maximize accuracy, with a robust assortment suitable for metal, wood, and plastic drilling tasks. This set emphasizes durable manufacturing for demanding use.
Champion Brute Platinum 29-Piece Set
Champion’s Brute Platinum line is built for longevity, featuring 135-degree split point geometry and a flat shank for quick chucking in keyless tools. The set is designed to drill faster and more accurately with less wander, while offering corrosion-resistant performance for mixed-material projects.
Drill America KFD29J-PC 29-Piece Set
This 29-piece Drill America set includes sizes from 1/16″ to 1/2″ in 64ths, offering a comprehensive range for professional projects. The black and gold oxide finish resists corrosion and increases hardness, while the high-speed steel construction provides solid wear resistance for routine drilling tasks.
Buying Guide
Key considerations when choosing US-made drill bits:
- Material compatibility: For wood, metal, and plastic, look for high-speed steel (HSS) as a baseline. For hardened metals, cobalt blends improve wear resistance.
- Point geometry: 135-degree split points help start holes accurately and reduce walking, especially on slick surfaces.
- Coatings: Titanium nitride and other coatings extend bit life and reduce friction, making them suitable for frequent drilling and challenging materials.
- Shank design: Three-flats or quick-change shanks provide better grip and reduce slippage in power tools across various chuck types.
- Size range: Sets with a wide range (e.g., 1/16″ to 1/2″ or larger) increase versatility for DIY and professional use.
- Durability features: Tapered webs, precision-ground flutes, and enhanced clearance improve durability and hole quality over time.
- Brand and warranty: Reputable US brands often offer better consistency and support for replacements or returns.
Comparative Notes
Compared to standard HSS bits, sets with 135° split points and premium coatings tend to cut cleaner, start more reliably, and last longer in mixed-material tasks. Coated bits are particularly beneficial for high-volume work or jobs involving stainless steel and hard alloys, while traditional HSS remains a versatile, cost-effective option for everyday use.
