Irwin 49618 1/2 Inch Brad Point Drill Bit 3-pack

Product Description

The IRWIN INDUSTRIAL TOOL CO 49618 is a 1/2-inch brad point drill bit sold in a 3-piece pack, designed for precision hole boring in wood-based materials. The brad point tip provides accurate centering before the cut begins, reducing wander on the workpiece surface. Spur cutting edges along the outer diameter shear wood fibers cleanly rather than tearing them, which minimizes splintering on entry and exit. Wide flutes evacuate chips continuously during the cut. The bit is precision ground to hold tight diameter tolerances, making it well suited where exact hole size is critical to fit and finish.

This bit is intended for use in furniture making, doweling, cabinetry, and other finish woodworking applications where hole quality and dimensional accuracy matter. The 1/2-inch diameter and 3-31/32-inch twist length support deep, clean holes in solid wood, plywood, and engineered wood panels. The overall length of 5-15/16 inches provides adequate reach in most bench-top and handheld drill applications. The pack of three makes it practical to keep a fresh bit available on larger production or service jobs.

Key Features

• Brad point tip centers accurately before cutting, preventing bit wander on smooth or angled surfaces
• Precision-ground diameter holds tight tolerances for doweling and joinery requiring exact fit
• Spur cutting edges shear wood fibers cleanly to reduce splintering and produce smooth hole walls
• Wide flutes promote continuous chip evacuation for faster, cooler cutting
• 3-31/32-inch twist length supports deeper holes without bit extension
• Comes pouched in a 3-piece pack for jobsite or shop use

Compatibility

Designed for use in standard 1/2-inch chuck handheld drills and drill presses for woodworking applications including furniture making, doweling, and cabinetry where exact hole sizing is required.

Installation Notes

Installation of brad point bits is performed by woodworkers and finish carpenters using handheld drills or drill presses. Secure the workpiece firmly before drilling to prevent movement during the cut. Use appropriate drill speed for the wood species and bit diameter — lower speeds generally apply for larger diameters. Inspect the bit for wear or tip damage before each use, as a dull or damaged brad point will compromise hole quality and increase splintering.
