Description

The DT4578-QZ is a DEWALT EXTREME 35mm Self-Feed Forstner wood drill bit with three extra-sharp cutting edges, designed for rapid drilling of clean, accurate flat-bottomed holes in hardwood, softwood, wooden boards, and plasterboard. The self-feed design uses a threaded pilot point that pulls the bit through the material, reducing the cutting force required from the operator and enabling faster drilling without excessive pressure.
Three extra sharp cutting edges — outer rim cutters and a centre point — deliver clean, splinter-free hole entry and exit, making Forstner bits the preferred choice for hinge drilling, shelf pin holes, dowel boring, and cable routing applications in cabinetry and joinery. The optimised cutting angle delivers longer bit life, and the superior heat treatment provides maximum durability in demanding wood drilling applications. The 35mm diameter is the standard size for Blum-style cup hinges used in kitchen and bedroom cabinetry throughout Europe, making this one of the most frequently specified Forstner bit sizes in kitchen fitting.
The 11mm (7/16-inch) quick-change hex shank enables fast, tool-free bit changes in cordless drill chucks and bit holders. The open tooth design allows for easy resharpening to extend working life. Compatible with all standard drill chucks and cordless drills.
