Dewalt Accessories DW1920 Split Point Drill Bit 5/16 in 3 Pack

Product Description

The DEWALT ACCESSORIES DW1920 is a 5/16-inch split point drill bit designed for clean, accurate drilling in wood, metal, and plastic. The pilot point tip starts on contact, eliminating the need for a center punch and reducing walk on hard surfaces. A no-spin shank locks firmly in the chuck to prevent slipping during high-torque applications. The tapered web construction adds durability and reduces the risk of breakage under load. This bit is sold in a pack of three and weighs 0.37 pounds. It is a standard choice for HVAC techs, electricians, plumbers, and general tradespeople who need reliable, repeatable hole quality across mixed materials.

This drill bit is suited for residential and light commercial trade work where consistent hole quality matters across a range of substrates. Common applications include drilling pilot holes in sheet metal for HVAC duct work, boring through wood framing for electrical or plumbing rough-in, and penetrating plastic enclosures or junction boxes. The 5/16-inch diameter fits a wide range of fastener and conduit clearance requirements encountered in day-to-day trade installations.

Key Features

• Pilot point tip starts on contact for clean, accurate holes without walking
• No-spin shank prevents bit spinning in the chuck during use
• Tapered web design reduces breakage and extends bit life
• Reduces lock-up on breakthrough for cleaner exit holes
• Size markings located above the shank to resist wearing away
• Suitable for drilling in wood, metal, or plastic

Compatibility

Designed as a standard 5/16-inch twist drill bit compatible with conventional 3-jaw keyed and keyless drill chucks used in corded and cordless drills across trade applications.

Installation Notes

Install in a properly sized drill chuck and verify the no-spin shank is fully seated before drilling. Always wear eye protection when drilling metal or plastic, as chips and burrs present a hazard. Reduce feed pressure as the bit approaches breakthrough to minimize grab and material tear-out. Inspect the bit tip for wear or chipping before each use and replace if the pilot point shows damage.
