Dewalt Accessories DWA1205 Cobalt Drill Bit 5/64 in 5-pack

Product Description

The DEWALT ACCESSORIES DWA1205 is a 5/64-inch cobalt split point drill bit designed for high-performance drilling in metal, wood, stainless steel, and heavy steel. The cobalt construction delivers significantly longer service life compared to standard black oxide bits, rated at approximately 4 times the longevity under comparable conditions. The split point tip engages the workpiece on contact, reducing walking and the need for a center punch. This bit is sold in a 5-piece pack and is appropriate for use by electricians, plumbers, HVAC technicians, and other trade professionals who regularly drill through ferrous and non-ferrous materials.

The DWA1205 is suited for repetitive metal drilling tasks encountered in residential and light commercial trade work. Common applications include drilling pilot holes in sheet metal, structural steel, stainless fastener clearance holes, and hardwood framing members. The cobalt alloy composition makes it particularly well-suited for harder materials that quickly wear down standard high-speed steel bits. The 5-piece pack format keeps replacements on hand for high-turnover drilling environments such as panel rough-in, mechanical room installations, and fabrication work.

Key Features

• Cobalt construction rated for approximately 4 times the service life versus black oxide bits
• Split point tip starts on contact, reducing bit walking on smooth or curved metal surfaces
• Optimized for drilling stainless steel and heavy steel where standard HSS bits fail prematurely
• Compatible with both metal and wood drilling applications
• Sold as a 5-piece pack, providing on-site backups for continuous trade use

Compatibility

Designed as a standard 5/64-inch diameter drill bit for use with corded and cordless drill drivers accepting standard round-shank bits. No specific model compatibility was provided by the manufacturer for this SKU.

Installation Notes

Cobalt drill bits should be installed by qualified trade professionals using appropriate drill drivers set to a suitable speed for the material being drilled. Always secure the workpiece before drilling and use cutting fluid or lubricant when drilling through stainless or heavy steel to extend bit life and reduce heat buildup. Wear appropriate PPE including eye protection whenever drilling metal. Inspect the bit for wear or tip damage before each use and replace if the cutting edges are degraded.
