Freud 1-1/2 in. Precision Forstner Bit features a double-ground, razor-sharp serrated edge that slices smoothly throughout the rotation of the bit, reducing splintering and chipping to create flat-bottom holes. Its unique geometric design includes multiple cutting edges that enhance shearing action, allowing for faster rotational speeds and more efficient cutting. Unlike competitive Forstner bits that produce small chips and dust which increase friction and heat, causing dulling, this bit maintains sharpness longer and delivers clean, precise holes with smooth edges that require no sanding. The bit is constructed with quality forged materials for extended life and includes an ultra-sharp spur to ensure an accurate starting hole. Its steep angled cutting edges produce smooth, flat holes and create chisel-like curls for fast, clean chip removal. Freud backs this product with a limited lifetime .
