FTG USA 6 Pc #8 (11/64″) Tapered Countersink Drill Bit Set with 1 Stop
This set is best for woodworkers who want a compact, adjustable-depth solution. The 6-piece kit includes a #8 (11/64″) countersink with a 3/8″ depth stop collar and a 1/8″ hex wrench. Its 4-flute countersink cutter and tapered drill bit design enable smooth chip flow and cleaner pilot holes in soft or hard woods. Choose this if you value depth control and a versatile starter set for common #8 screws.

The magnetic extension bit holder and included Allen wrench aid extended reach and setup. Best for: projects requiring multiple countersink sizes and a durable, versatile toolkit. Caution: ensure proper storage to prevent magnetic holder from snagging metal objects.

Buying Guide: Key Considerations for #8 Countersink Drill Bits
- Depth control: Look for depth stops or adjustable collars to ensure consistent countersinking depth for repeatable results.
- Flute design: Four-flute or two-flute designs affect chip evacuation and cutting speed. More flutes can improve accuracy but may wear differently.
- Material and coating: Titanium-coated high-speed steel (HSS) offers durability for softwood and hardwood. Coatings influence wear resistance and longevity.
- Shank compatibility: Ensure the bit’s shank matches your drill chuck (hex shank vs. round shank) for secure grip, especially in impact drivers.
- Set size and versatility: A larger set with multiple countersink sizes covers more projects, but a compact set can be quicker to use for simple tasks.
- Bit geometry and angle: Most #8 countersinks use an 82° to 90° countersink angle; choose according to screw heads and project requirements.
- Replacement parts and accessories: Some brands offer replaceable bits, magnetic extensions, and case storage; consider long-term maintenance.
Frequently Asked Questions
- What size is a #8 countersink?
– A #8 countersink is typically 11/64 inch in diameter for the countersink portion, designed to pair with #8 screws. - Do I need a depth stop for countersinking?
– A depth stop helps achieve consistent screw depths, reducing the risk of countersink overdriving and screw heads sitting too deep. - Can I use these bits in a drill/driver with a standard chuck?
– Yes, most kits are designed to fit standard 1/4″ chucks; hex shank variants are compatible with quick-change chucks and impact drivers. - Is a two-flute design better than a four-flute design?
– Two-flute bits cut faster and are often better for larger or deeper countersinks, while four-flute bits can offer smoother finishes in certain woods. - Are these sets suitable for hardwood and softwood alike?
– Most sets perform well in both, with titanium-coated HSS providing durability for hardwoods and softwoods alike. - Should I buy a kit with replaceable bits?
– Replaceable bits extend the life of the set and allow quick swapping without replacing the whole bit assembly.
