Famag 4-Piece Set - 7-Flute Countersink for Wood, Composites, Panels and Acrylics - 10, 13, 16, 20mm Ø Countersinks

These Famag seven-fluted countersink bits feature a 90° countersink angles and an irregular flute pitch. The fully ground tool head delivers exceptionally smooth, chatter-free results, even in challenging materials.

Designed for precision countersinking in all types of wood-including softwoods, hardwoods, and veneered or laminated panels—this tool also performs reliably on a variety of plastics and acrylics. The innovative irregular pitch grind features unevenly spaced flutes that disrupt vibration patterns, reducing chatter and producing smoother cuts, cleaner countersinks, and less risk of surface tearing or frayed edges—especially when drilling softwoods or using hand drills.
