Why You'll Love This Set
- Premium HSS Construction: Crafted from high-speed steel (HSS) cobalt alloy with outstanding wear, impact, and corrosion resistance — built to handle frequent, heavy-duty use without dulling.
- Low-Friction Titanium Nitride Coating: The golden titanium nitride surface coating dramatically reduces friction and heat build-up during drilling, enabling smoother cuts and extending bit life well beyond uncoated alternatives.
- Complete Size Coverage: One set covers nearly all common drilling and countersinking needs, eliminating the need to purchase individual bits separately and saving valuable storage space in your workshop.
- Universal 1/4" Hex Shank: The standard hexagonal shank fits virtually all electric drills, impact drivers, and power tools. Snap in and out quickly — no slipping, no fumbling.
- Automatic Center Punch Included: The spring-loaded brass center punch lets you mark precise drilling positions without a hammer. No more wandering bits or off-center holes — just accurate, consistent results every time.

Frequently Asked Questions
Q: What materials can these titanium countersink drill bits be used on?
A: These 5-flute titanium-coated HSS countersink drill bits are suitable for use on wood, plastic, and soft metal sheets. They are ideal for DIY woodworking, furniture assembly, home maintenance, and light industrial projects. They are not recommended for hardened steel or masonry.
Q: What is included in the set, and what sizes are available?
A: The set is available in either a 3-piece or 5-piece configuration. Each set includes multiple countersink drill bits of varying sizes to cover common drilling and countersinking tasks, plus one automatic center punch with a knurled brass body for precise position marking. Please refer to the product images for exact size details.
Q: Will these bits fit my existing drill or impact driver?
A: Yes! All bits feature a standard 1/4-inch hexagonal (hex) shank, which is compatible with the vast majority of electric drills, cordless drills, and impact drivers available on the market. The hex design also prevents bit slipping during operation.
Q: What is the automatic center punch and how does it work?
A: The included automatic center punch is a spring-loaded tool with a knurled non-slip brass body. Simply press the tip firmly onto your workpiece surface at the desired drilling location — the internal spring mechanism releases a sharp strike that leaves a clean indent, helping guide your drill bit and preventing it from wandering off-center. No hammer required.
