BIT CSINK #14 1/4" HSS

PRODUCT DESCRIPTION:

The Irwin 1882785 Countersink Drill Bit is a high-speed steel tapered bit designed for woodworking applications, specifically for #14 screws. Measuring 1/4-inch in diameter with an overall length of 4?3/4 inches, it combines pilot drilling and countersinking in a single step, saving time and ensuring precise screw placement. Its 4-flute design efficiently removes chips, while the adjustable four-cutter counterbore allows for controlled depth and a smooth finish around screw heads. Equipped with a 1/4-inch quick-change shank, the bit provides secure attachment to drills and quick swapping, making it ideal for cabinetry, decking, and other wood projects requiring clean, professional results.

ADDITIONAL FEATURES:

Widened flutes: facilitate quicker chip removal so less heat, cleaner cuts.

Saves time: pilot drilling + countersinking in one pass.

Clean finish: widened flutes + counterbore help reduce tear-out, chip-glazing, and messy edges.

Quick-change shank helps with secure grip and fast swaps.

INSIGHTS:

Use a slower speed in dense hardwood or near edges to avoid burning; with the wider flutes and counterbore, chip load can increase.

Clean chips often, especially from the flutes and the counterbore area, to maintain cutting efficiency and finish.

Secure the workpiece and ensure your drill chuck / quick-change adapter is tight; long length plus torque from the counterbore can induce chatter.
