Drill bit DeWalt DT4875-QZ, 600 mm length, single piece

DeWalt DT4875-QZ drill bit, 600 mm length, single piece is designed for drilling deep or hard-to-reach holes in woodworking and renovation tasks. The bit is compatible with standard drill chucks and combines a long, rigid shaft with a tip geometry suited for clean, accurate holes in hardwood, softwood and laminate. The drilling and clamping parts are threaded and glued together, and a tapered transition between drill and clamp facilitates tool removal from the hole.

Advantages

The extended 600 mm length provides reach for deep drilling without the need for extensions. Threaded and glued connection between drilling and clamping parts ensures secure assembly and consistent concentricity during rotation. The tapered transition between the drill and the clamp reduces friction and allows easier extraction from drilled holes, which helps preserve workpiece edges and finish quality. Tip and flute design are optimized for fast, accurate and clean hole results in wood-based materials.

Suitable for

• Creating deep holes in hardwood, softwood and engineered boards
• Renovation and construction tasks requiring extended reach
• Installing long fasteners, dowels or conduit runs through timber
• Work where standard-length bits cannot reach or would require extensions

Key specifications

• Overall length: 600 mm
• Format: single piece (one drill bit)
• Compatibility: standard drill chucks
• Material application: hardwood, softwood, laminate and wood-based panels
• Connection: threaded and glued drilling-to-clamp assembly
• Design feature: tapered transition for easy removal from holes

How to use

Fit the DeWalt DT4875-QZ into a compatible drill chuck and tighten securely before starting. Mark the drilling position and start at low speed to establish the hole, then increase speed as appropriate for the material while maintaining steady feed pressure. For long-reach drilling, keep the drill axis aligned with the intended hole to avoid binding. Withdraw the bit periodically to clear chips when drilling deep holes in dense materials. After use, clean flutes and store in a dry place.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. For best results in hardwood and laminates, select drill speeds and feed rates that prevent burning or splintering; allow chip clearance by withdrawing the bit occasionally during deep drilling. Ensure the drill and chuck are rated for the length and torque required to avoid runout or vibration.
