1/4″-1/2″x12″ HSS Aircraft Extension Drill Bit Set Plastic Case Pouch

$41,99

Manufactured to Aerospace Standard 907. The 135 degree split point is self-centering and reduces thrust. Ideal for drilling in mild steel where extra length for reach is required. They have a black oxide surface treatment that is abrasion resistant, reduces chip welding and improves chip flow. Sizes smaller than 1/16 and #52 have the 118 degree standard point. Sizes included are 1/4″, 5/16″, 3/8″, 7/17″ and 1/2″ with overall length of 12″
