Premium alloy construction delivers outstanding strength, impact resistance, and long-lasting sharpness. The precision-ground helical cutting edges create smooth, clean countersinks and counterbores specifically optimized for 82-degree screws, helping reduce tear-out and improving screw seating results.
Upgraded aluminum depth stop collar lets you set precise drilling depths quickly and securely, reducing guesswork and material damage. This durable collar design minimizes wear compared to traditional styles, while the included wrench allows easy adjustment to match project requirements and maintain consistent drilling control.
Engineered for multi-material versatility, this countersink drill bit set works perfectly on wood, plywood, MDF, particle board, and aluminum. Whether you are tackling cabinetry, furniture building, decorative projects, or general repairs, these bits deliver reliable performance and clean finish on a wide range of surfaces.
Complete bits kit includes 5 two-flute tapered drill countersink bits in popular sizes: 1/8"x3/8", 9/64"x3/8", 5/32"x3/8", 11/64"x1/2", and 3/16"x1/2". Also comes with a convenient wrench and one adjustable stop collar, all featuring a 1/4 inch hex shank compatible with most standard drills and drivers.
Organized storage case features individual compartments to keep each countersink bit securely in place and protected from damage during transport or when not in use. For optimal performance and cleaner edges on delicate materials, operate the bits at slow speeds around 200 RPM to reduce heat buildup and improve finish quality.
