88702 Speedbor Bit Extension, 1/4 In. Shank, 6 In., Steel

The Irwin 88702 Speedbor Bit Extension is a precision-engineered accessory designed to add critical length to your 1/4-inch round-shank drill bits. Forged from high-quality tool steel, this extension enables you to reach deep or obstructed holes without changing tools, saving time on demanding drilling projects. Whether you're working in tight spaces, drilling through thick materials, or accessing hard-to-reach areas, this 6-inch extension delivers the reach you need while maintaining solid alignment and stability.

This extension solves the common problem of limited drill bit length by accommodating 5/8-inch and larger diameter bits, giving you flexibility across a wide range of drilling applications. The heavy-duty construction resists wear and reduces wobble during operation, ensuring cleaner holes and protecting both the extension and your drill bits from premature wear.

Features and Benefits

• Compatible with 1/4-Inch Round-Shank Bits: Designed for wood bits with 1/4-inch round shanks featuring three flats, guaranteeing a secure, slip-free fit.
• Handles 5/8-Inch and Larger Bits: Engineered to follow larger diameter bits through the hole, expanding your tool flexibility.
• Included Allen Wrench: Comes with a matching Allen key for quick adjustments on the job site without needing additional tools.
