Built for metal brackets, woodworking pilot holes, cabinetry, hobbies, and repairs.
Reduces surface friction and heat buildup so cutting edges stay sharp up to 3x longer.
10 bits per size across 1.0, 1.5, 2.0, 2.5, and 3.0 mm so you always have fresh sharp bits on hand.
Bites cleanly on contact with steel, aluminum, and hardwood without skating across the surface.
Keeps all 50 bits organized upright on your workbench—plus a free spring center punch.
Spiral flutes are coated in hard gold Titanium Nitride for fast chip ejection, while uncoated silver shanks grip tightly inside your drill chuck without slipping.
From cabinet hardware to steel angle brackets, having the exact pilot diameter prevents split wood and snapped screw heads.
Press the free spring-loaded center punch onto metal to create a starter dimple with one hand—no hammer needed.
