Description

The DEWALT ACCESSORIES DW1612 is a high-speed split point drill bit designed for demanding drilling applications in metal, wood, and plastic. Measuring 7/16 inches in diameter and 12 inches in length, this bit features a 135-degree split point that enables quick starts without walking on the workpiece surface. The 31-degree helix reduces the over-aggressiveness common with true parabolic flute designs, while the parabolic flute geometry accelerates chip ejection to keep the cutting zone clear. A black oxide coating extends wear resistance on the industrial-grade steel body, making this bit a reliable choice for trade and production use.

This drill bit is suited for electricians, plumbers, HVAC technicians, and general contractors who regularly drill through metal framing, wood studs, and plastic conduit or enclosures. The 12-inch length provides extended reach for drilling through thick structural members or wall assemblies without requiring an extension. Sold in a package of 5, the DW1612 is a practical stock item for service vans, job boxes, and shop use where bit turnover is frequent.

Compatibility

Designed for drilling in metal, wood, and plastic. Compatible with standard drill chucks accepting a 7/16-inch shank bit on corded or cordless drill drivers used in trade applications.

Installation Notes

Licensed electricians, plumbers, and HVAC technicians are the typical installers of long-series drill bits of this type. Secure the workpiece before drilling and use appropriate RPM settings for the material being drilled slower speeds for metal, higher speeds for wood and plastic. Wear appropriate eye protection and ensure the drill chuck is firmly tightened before operation. Do not use damaged or bent bits, as they can fail unexpectedly under load.
