Aircraft Extension

Triumph Aircraft Extension Drill Bits are 6" long and ideal for drilling in harder to reach places. Made of high speed steel with a black oxide finish, these bits can withstand high heat and pressure and will better resist corrosion. 135 degree split point helps reduce walking and scarring for straighter, more precise penetration.

		Point:	135° Split Point
		Material:	High Speed Steel
		Coating/Finish:	Black Oxide
		Other:	Heavy-Duty Construction
