Dewalt Accessories DWAMDCE12 Cobalt Drill Bit 3/16 in 5-pack

Product Description

The DEWALT ACCESSORIES DWAMDCE12 is a 3/16-inch cobalt alloy steel jobber-length drill bit sold in a 5-pack. Cobalt alloy construction gives the bit the heat resistance and hardness needed to cut through stainless steel, hardened steel, and other tough metals without premature wear. The tip geometry is engineered to start on contact, reducing the tendency to walk on smooth or curved metal surfaces. These bits are a standard choice for electricians, pipefitters, HVAC technicians, and general tradespeople who regularly drill into hard-metal substrates during installation and service work.

These bits are suited for drilling into stainless steel, high-carbon steel, cast iron, and other hard metals encountered in commercial and residential trade applications. The jobber-length profile provides a balance of reach and rigidity appropriate for hand-held drills and drill presses. The 5-pack quantity is practical for shop stocking or jobsite kits where bit breakage or dulling in hard metal is a regular occurrence.

Key Features

• Cobalt alloy steel construction for extended performance in hard metals and stainless steel
• 3/16-inch diameter, jobber-length profile for reach and rigidity
• Tip designed to start on contact and minimize walking on metal surfaces
• Sold as a 5-pack for consistent on-hand availability during high-volume work
• Engineered for durability under the heat generated by hard-metal drilling

Compatibility

Designed as an OEM-style replacement-grade cobalt drill bit compatible with standard 3/8-inch and 1/2-inch keyed or keyless drill chucks accepting 3/16-inch round shanks, suitable for use in corded drills, cordless drills, and drill presses.

Installation Notes

Cobalt drill bits for metal should be installed by the appropriate trade professional following applicable safety practices. Always secure the workpiece before drilling and use cutting fluid or oil when drilling into stainless steel or hardened metals to reduce heat buildup and extend bit life. Do not exceed the recommended RPM range for the bit diameter and material being drilled. Inspect bits for chipping or dulling before each use and replace as needed to maintain cut quality and prevent workpiece damage.
