Q: What sizes are included in this 22-piece set?
A: While specific sizes may vary, typical 22-piece sets include fractional inch sizes ranging from 1/16" to 1/2" in common increments, covering the most frequently used bit sizes for general drilling applications. Check the product packaging or case labeling for the exact sizes included in this RYOBI A972202 set.
Q: What's the advantage of titanium-coated bits over regular drill bits?
A: Titanium coating provides multiple benefits: reduced friction for faster drilling, lower heat buildup that extends bit life up to 3x longer than standard high-speed steel bits, improved hardness for drilling harder materials, and better corrosion resistance. The coating also helps bits stay sharper longer, maintaining cutting performance through more holes.
Q: Can these bits drill through hardened steel or stainless steel?
A: While titanium-coated bits are more durable than standard HSS bits and can handle mild steel and softer metals effectively, they may struggle with hardened steel or thick stainless steel. For those extremely hard materials, consider cobalt drill bits which are specifically designed for tough metal drilling. These titanium bits excel at general-purpose drilling in wood, plastic, aluminum, and mild steel.
Q: Will these bits work with my cordless drill or do I need a drill press?
A: These bits work perfectly with standard cordless drills, corded drills, drill/drivers, and drill presses. The 135-degree split point design helps prevent walking even when using handheld drills, making them ideal for both portable and stationary drilling applications. For best results, use appropriate drilling speed for the material (slower for metal, faster for wood) and apply steady, consistent pressure.
