Stanley lxah99414pb Pilot Drill Bit 0.25 in 4.25 in L

Product Description

The STANLEY lxah99414pb is a carbon steel pilot drill bit designed to guide hole saws during cutting operations. At 0.25 inches in diameter and 4.25 inches in overall length, it provides the reach and stability needed to keep a hole saw centered and tracking true through the cut. The round shank seats securely in standard drill chucks. This bit is a direct working component in hole saw assemblies, keeping cuts accurate and reducing wander on entry. Electricians, plumbers, and HVAC technicians rely on pilot bits like this one when cutting through wood, thin metal, and composite materials during rough-in work.

This pilot drill bit is suited for use with compatible hole saw mandrels and arbors in residential and light commercial applications. It is commonly used during rough-in installations where repetitive hole cutting is required — conduit runs, pipe penetrations, and duct openings. The 4.25-inch length provides adequate depth for most standard wall and joist penetrations encountered in trade work.

Key Features

• Carbon steel construction for durability through repeated use
• 0.25-inch bit diameter for standard hole saw pilot applications
• 4.25-inch overall length for reach through deeper material sections
• Round shank design compatible with standard drill chucks
• Functions as a centering guide to reduce hole saw wander on entry

Compatibility

Designed as an OEM-style replacement or service pilot bit for use with hole saw mandrels and arbors that accept a 0.25-inch round shank pilot drill.

Installation Notes

This pilot drill bit is installed by trade professionals including electricians, plumbers, and HVAC technicians as part of a hole saw assembly. Secure the round shank fully into the drill chuck before use and confirm the set screw or chuck jaws are tightened. Inspect the bit tip for wear or damage before each use, as a dull or damaged pilot bit can cause the hole saw to walk off center. Always follow applicable safety practices for rotary cutting tools and wear appropriate eye protection.
