Drill bit DeWalt DT4873-QZ, length 600 mm, single piece

DeWalt DT4873-QZ drill bit, 600 mm length, single piece is a long solid drill bit designed for deep drilling tasks in woodworking and general construction. Engineered for use with compatible drills and chucks that accept its shank and diameter, this 600 mm bit enables extended reach for creating deep, precise holes in hardwood, softwood and laminate. The drilling and clamping parts are threaded and glued together, and a tapered transition between the drill and the clamp facilitates easy removal of the tool from the drilled hole.

Advantages

This long drill bit offers extended reach for deep-hole applications while maintaining drilling accuracy and a clean hole finish in hardwood, softwood and laminate. The threaded and glued connection between drilling and clamping parts increases structural integrity during heavy-duty use. The tapered transition between the drill and clamp reduces friction when extracting the bit from the hole, which helps prevent jamming and preserves the workpiece surface.

Suitable for

• Deep-hole drilling in construction framing and structural timber
• Carpentry tasks requiring extended reach, such as drilling through stacked boards
• Maintenance and repair work where access is limited and long-reach drilling is needed
• Drilling clean holes in hardwood, softwood and laminated panels

Key specifications

• Length: 600 mm
• Design: single-piece long drill bit with integrated clamp section
• Materials suitability: hardwood, softwood, laminate
• Connection: threaded and glued joint between drilling and clamping parts
• Feature: tapered transition between drill and clamp for easier extraction

How to use

Select a compatible drill and chuck that accept the bit’s shank and diameter, secure the bit firmly in the chuck, and set an appropriate speed for the material being drilled. Position the drill perpendicular to the work surface, apply steady forward pressure, and allow the bit to clear chips periodically to maintain cutting efficiency. After reaching the required depth, withdraw the drill while running at low speed if necessary; the tapered transition aids removal. Inspect the hole and clean any remaining debris before finishing the workpiece.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection, and follow the drill manufacturer’s guidance for maximum speed and clamping. For harder woods, use moderate feed pressure and periodically pull the bit out to clear chips to avoid overheating. Ensure the drill’s chuck securely holds the shank to prevent slippage during deep drilling.
