Dewalt DW1925 Reduced Shank Drill Bit 25/64 in Hss

Product Description

The DEWALT DW1925 is a reduced shank twist drill bit designed for drilling into metals and wood. It features a 25/64 inch cutting diameter with a 3/8 inch straight-cylindrical shank, allowing it to fit standard 3/8 inch chucks even though the cutting diameter exceeds that size. The 135-degree split point tip reduces walking on contact and requires less feed pressure than a conventional 118-degree point. Manufactured from high-speed steel with an oxide straw finish, the DW1925 is suited for production drilling and general-purpose trade applications. Licensed electricians, plumbers, pipefitters, and HVAC technicians commonly use bits like this for panel knockouts, conduit entry, and pipe penetrations.

The DW1925 fits drilling applications in residential and light commercial construction where a 3/8 inch chuck drill is on hand but a larger hole diameter is required. The reduced shank design eliminates the need for a larger drill motor or a separate chuck upgrade. Primary workpiece materials include ferrous and non-ferrous metals as well as wood. The right-hand spiral flute with regular helix evacuates chips efficiently during through-hole drilling. At 5 inches overall length with a 3-3/4 inch flute, this bit handles most standard material thicknesses encountered in field work.

Key Features

• Reduced 3/8 inch shank fits standard 3/8 inch chuck drills while cutting a 25/64 inch hole
• 135-degree pilot point reduces bit walking and lowers required feed force on metal surfaces
• High-speed steel construction withstands heat generated during metal drilling
• Oxide straw finish provides basic lubricity and corrosion resistance during storage
• Right-hand spiral flute with regular helix promotes consistent chip evacuation
• 3-3/4 inch flute length supports drilling depths up to 3.75 inches

Compatibility

Designed as an OEM-style replacement or direct-use drill bit compatible with any 3/8 inch keyed or keyless chuck drill driver used in metal and wood drilling applications.

Installation Notes

This bit is installed and removed by a licensed or qualified tradesperson using a standard chuck key or keyless chuck mechanism. Secure the workpiece before drilling and wear appropriate eye protection. When drilling metal, apply a suitable cutting fluid to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if the point shows signs of chipping or excessive wear.
