Dewalt DW2539 Mechanics Drill Bit Size 10 Hss 3.75 in

Product Description

The DEWALT DW2539 is a wire gauge size 10 mechanics drill bit constructed from high-speed steel (HSS). It is designed for drilling precise, clean holes in metal and other hard materials in preparation for countersinking operations. The bit measures 3.75 inches in overall length and features a 3/16-inch hex shank for secure, slip-resistant seating in compatible drivers and drill chucks. Weighing 0.75 pounds, it is a single-piece bit intended for professional-grade use in mechanical and fabrication applications.

This bit is suited for use in metal fabrication shops, automotive service environments, and general mechanical work where wire gauge sizing is required. Its 3/16-inch hex shank allows it to seat firmly in hex-drive drill chucks and quick-change systems. It is rated for use with counter sinks, making it a practical choice when a countersink operation follows the drilling step. Intended for licensed tradespeople, mechanics, and skilled technicians working with HSS-compatible materials.

Key Features

• Wire gauge size 10 diameter for precise, standardized hole sizing
• High-speed steel construction for durability in metal and hard-material drilling
• 3.75-inch overall length provides reach in confined or deep-set applications
• 3/16-inch hex shank for secure fit in hex-drive chucks and quick-change systems
• Rated for use with counter sinks for multi-step fastener seat preparation

Compatibility

Designed for use with counter sinks and compatible with hex-drive drill chucks and quick-change driver systems accepting a 3/16-inch hex shank. Suitable for applications requiring wire gauge size 10 hole specifications.

Installation Notes

Installation and use of this bit should be performed by qualified mechanics or tradespeople familiar with drill press or power drill operation. Secure the hex shank fully in the chuck before operation to prevent slippage. Always power down and disconnect the tool before changing bits. Use appropriate cutting fluid or lubricant when drilling through hardened metals to extend bit life.
