New Precision Shear Forstner Bits feature a double-ground, razor-sharp serrated edge that slices throughout the rotation of the bit for less splintering and chipping, producing flawless flat-bottom holes. This unique geometric design has multiple cutting edges that produce greater shearing action, allowing for faster rotational speeds and more efficient cutting. Competitive Forstner Bit designs produce small chips and dust that collect in the cutting area, increasing friction and heat, thus causing the bit to dull quickly. Those designs also create holes with rough edges that require sanding. In addition to serrated edges, Presision Shear Forstner
Hardened Steel Body warrants a longer life and sharper cutting edge. Ultra Sharp Spur ensures an accurate hole and resists walking on material. Steep Angled Cutting Edges produce holes that are smooth and flat, and create chisel-likecurls for fast, clean chip removal. Quality Forged Construction instead of casting, strengthens bits for extended life.
