Product Information
Full details
The DART Ultra Speed Flat Bit Set is designed for professional carpenters, electricians, and serious DIY enthusiasts who require efficient, high-speed drilling in wood, plastic, and plasterboard. Its primary benefit is a specialized threaded tip that enables up to 5x faster drilling speeds with minimal manual effort, though users should be aware that the aggressive pull of the lead screw requires a firm grip on the drill to maintain control.

FAQs
Can I use these bits in a standard drill?
Yes, they are compatible with both standard drill drivers and impact drivers as long as the chuck accepts 1/4 inch hex shanks.
Are these bits suitable for metal drilling?
No, these are designed specifically for wood, plastic, and plasterboard. Attempting to drill metal will ruin the cutting edge.
How long are these bits?
All bits in this set have a standard length of 152mm.
Do I need to sharpen the lead tip?
The threaded tip is precision-machined. Sharpening is generally not recommended as it may alter the geometry and speed performance of the bit.
What happens if I hit a nail?
Hitting metal will likely dull the cutting spurs and the lead thread, reducing the bit's effectiveness and its ability to pull into the wood.
Troubleshooting
The bit is vibrating excessively.
Ensure the bit is fully seated in the chuck and that you are not applying too much side-force during the initial engagement.
The bit is getting stuck in the wood.
Reverse the drill momentarily to clear accumulated wood chips from the flutes, then continue at a slightly higher speed.
Hole edges are fraying.
Ensure you are using the correct bit size and allow the spurs to cut the outer perimeter fully before applying full drilling pressure.
Pros and Cons
Pros
- Drills up to 5x faster than standard flat bits
- Minimal downward pressure required
- Clean entry/exit holes due to double side spurs
- Universal 1/4 inch hex shank for quick changes
- Comprehensive size range in a portable wallet
Cons
- Aggressive threaded tip may be difficult to control in thin, brittle material
- Not suitable for drilling through metal or hardened materials
- Length is fixed at 152mm which may limit deep hole applications
Setup, Compatibility & Care
These bits are compatible with any drill or impact driver featuring a 1/4 inch hex quick-release chuck. To setup, simply pull back the chuck collar, insert the hex shank until it clicks into place, and ensure it is fully seated before activating the tool. To maintain the life of your bits, avoid contact with embedded nails or screws, which can chip the hardened cutting edges. After use, wipe the bits with a light machine oil to prevent surface corrosion, and return them to the provided fabric wallet to ensure the lead threads remain sharp and undamaged.
