The DEWALT ACCESSORIES DD5104 is a 1/4 inch titanium-coated impact drill bit sold in a 2-piece pack. It is engineered for fast, accurate drilling in metal, wood, and plastic. The patented Pilot Point tip prevents the bit from walking on contact, so holes start clean and on target. The tapered core adds structural strength, and optimized flute geometry pulls chips away from the cutting edge quickly. Licensed tradespeople and experienced DIYers use these bits with impact drivers and standard drill-drivers where precision entry and long service life are priorities.
This bit is suited for general-purpose drilling tasks across multiple materials including steel, aluminum, hardwood, softwood, and plastic sheet. The titanium coating reduces heat buildup during high-cycle use, extending cutting life compared to standard high-speed steel bits. Typical applications include mechanical, electrical, and woodworking rough-in work where a single bit set needs to handle varied substrate types on the same job site.
Designed as an OEM-style replacement and general-purpose drill bit for use in standard 3/8 inch and 1/2 inch chuck drill-drivers and impact drivers that accept 1/4 inch round shank bits.
Installation of drill bits should be performed with the tool unplugged or the battery removed before inserting or changing bits. Ensure the chuck or quick-connect collar is fully seated and locked before applying power. A licensed electrician, plumber, HVAC technician, or general contractor following applicable NEC or local building code requirements should confirm proper hole placement in structural or code-governed assemblies. Do not exceed the recommended speed range for the material being drilled.
