FAQ

How does one-step countersinking work?

The integrated bit drills the pilot hole and the 4-edge chamfer tool cuts the countersink in the same pass, so the screw head seats flush automatically.

Can I adjust the countersink depth?

Yes — the depth is adjustable for different screw head heights and material thicknesses.

Can this product be private-labeled?

Yes — custom branding, packaging and bulk programs are available.
