Dewalt Accessories DWAMDCE11 Cobalt Drill Bit 11/64 in 5-pack

Product Description

The DEWALT ACCESSORIES DWAMDCE11 is an 11/64-inch cobalt alloy steel jobber-length drill bit sold in a 5-pack. Built for cutting through stainless steel and other hard metals, the bit features a tip geometry engineered to start on contact and resist walking at the point of entry. Cobalt alloy steel construction gives the bit greater heat resistance than standard high-speed steel, extending cutting life in demanding applications. Licensed electricians, plumbers, HVAC technicians, and general contractors reach for cobalt bits when drilling through harder substrate materials that would quickly degrade a standard twist bit.

This bit is suited for trade and industrial applications where stainless steel fastener holes, conduit entry points, or bracket mounting holes must be drilled cleanly through hard metal stock. The jobber-length body balances reach and rigidity for general-purpose drilling in metal fabrication, mechanical rooms, equipment panels, and structural metalwork. Each pack contains 5 individual bits, making it practical to keep spares on hand for high-wear applications.

Key Features

• Cobalt alloy steel construction for improved heat resistance and durability in hard metals
• 11/64-inch diameter jobber-length bit
• Tip geometry designed to start on contact and minimize walking without a center punch
• Engineered specifically for stainless steel and other hard metal applications
• 5-pack quantity supports high-use or multi-technician job sites

Compatibility

Designed as an OEM-style replacement and standard jobber-length cobalt drill bit compatible with 3-jaw keyed or keyless drill chucks accepting 11/64-inch round shanks on corded and cordless drill/drivers.

Installation Notes

Cobalt drill bits should be installed and tightened securely in the chuck before operation. Use appropriate cutting fluid or lubricant when drilling stainless steel to reduce heat buildup and extend bit life. Allow the bit to do the work at moderate speed and consistent pressure rather than forcing feed rate. Wear appropriate eye protection per jobsite safety requirements when drilling metal.
