This drill is a Type 128-AG with a 3/8 inch reduced shank. Special Hi-Molybdernum tool steel. 135 degrees split point for fast penetration and accurate starting without center punch. Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance. Body and clearance are gold surface treated for maximum lubricity.
