Double End Drill Bits
Choose twin end drill bits when your machining project requires drilling through thin metals, plastics or wood. The short flute and overall length provide extra rigidity. Double ended drills feature a 135-degree split point that ensures fast and accurate hole starting without a center punch. Choose from two grades of twin end drills. Super Premium Drills are crafted with a special Hi-Molybdenum tool steel that is gold surface treated for maximum lubricity. Heavy-Duty Twin-End Drills feature a black oxide finish that helps retain drilling lubricants. Both styles are available in fractional sizes from 3/32" to 1/4" as well as #10, #11, #20 and #30 wire sizes.
