Freud Precision Shear PB-009 Forstner Bit, 1-1/4 in Dia, 3-1/2 in OAL, Forstner Bit, 3/8 in Dia Shank

New Precision Shearâ„¢ 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 Precision Shearâ„¢ Forstner bits has serrated edges.
