## Summary description

DeWalt DT70790-QZ pilot drill bit designed for use with hole saws. Intended for drilling in wood, this pilot bit guides the hole saw and ensures accurate start and stable cutting. Compatible with standard hole saw arbors, it is used in woodworking, installation of fixtures, and creating clean starter holes for circular cutting operations.

## Long description

The DeWalt pilot drill bit DT70790-QZ is designed to work with hole saws for accurate starter holes in wood. It combines a pilot drill point with a conical countersink to centre the chamfer on the clearance hole, helping to stabilise the hole saw and reduce wandering during circular cutting operations. Compatible with standard hole saw arbors, this pilot bit supports clean, reliable starts when cutting holes for fixtures, pipes, vents or cable access in wooden substrates.
Advantages
This pilot drill bit features an integrated countersink that keeps the conical chamfer centred on the clearance hole, improving alignment and finish. The design allows use with flip-and-drive connectors so you can drill pilot holes, countersink and then flip the bit to drive screws without re-chucking, which saves time on multi-step jobs. The bit’s geometry and finish are optimised for wood, providing stable cutting, consistent guidance for the hole saw, and faster task completion.
Suitable for
Creating starter holes for hole saws in soft and hardwoods
Installing door hardware, locks and circular fixtures in wooden doors
Cutting holes for pipes, vents and cable grommets in timber panels
Carpentry and joinery tasks that require centred pilot holes and clean countersinks
Key specifications
Type: Pilot drill bit with integrated countersink
Application material: Wood (softwood and hardwood)
Compatibility: Standard hole saw arbors and flip-and-drive connectors
Finish: Dark/black surface treatment for reduced friction
Function: Guides hole saw and provides centred chamfer for countersinking
How to use
Secure the pilot bit in the hole saw arbor or flip-and-drive connector according to the arbor manufacturer’s instructions. Position the pilot point at the intended hole centre and drill at moderate speed, applying steady pressure until the pilot point and countersink have entered the material. The pilot bit will keep the hole saw aligned; continue cutting with the hole saw to the required depth. For screw-driving operations with a flip-and-drive connector, stop, flip the bit and proceed to drive screws without changing tools.
Usage recommendations
Use appropriate personal protective equipment, clamp the workpiece to prevent movement, and select a hole saw size matched to the fixture. For best results in hardwood, reduce feed rate and use intermittent drilling to avoid overheating. Inspect the pilot bit before use and replace it if the tip or countersink shows signs of wear to maintain accurate guidance.
