Bosch BL4140 13/64" Black Oxide SP Jobber Drill Bit (Bulk)


Product Description

Bosch designed the new High-Speed Steel Black Oxide drill bits for all-purpose heavy-duty drilling in wood, plastic, carbon and alloy steels, aluminum and soft cast iron. With triple tempered black oxide coating, these Bosch bits will last 50-percent longer than standard uncoated high-speed drill bits. Since heat is the single largest hindrance to the life of a bit, Bosch designed a special coating that gives each bit a high level of lubricity to reduce heat build up and prolong the life of each bit. Whether a professional or serious do-it-yourselfer, precise holes and longer lasting bits make a big difference in any job or project. And since Bosch understands that time is money, it combined features like a 135-degree spilt point that starts on contact and enlarged flutes with a high helix for faster material removal to make these Black Oxide bits three-times faster than standard drill bits on the market.

Must be purchased in multiples of 12

  • The speed helix design penetrates 3X faster than standard bits which means easier drilling, reduced heat, extended drill bit life and extended cordless battery life
  • Triple tempered black oxide coated bits last 50% longer than regular high speed steel and offer reduced friction between bit and workpiece
  • 135° split point starts on contact with no walking or skating and no center punch is required
