Product Details
The Bosch® BL4151 drill bits come in bulk and feature a jobber length with a diameter of 3/8 inches and a black oxide finish. They utilize a speed helix design, allowing for three times faster drilling compared to standard bits, and they last 50% longer than high-speed steel alternatives. The design promotes easier drilling, reduces heat, and extends the overall life of the drill bits. These drill bits are available in various lengths including jobber length, stubby length, and extended length (aircraft), as well as a 1/2 inch reduced shank (Silver and Deming). They are suitable for use in a wide range of materials including steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon, and composite materials.
