The DEWALT DW1162 bit set includes 14 bits with no spin shanks for easy secure drilling. These bits have a black oxide finish for greater wear protection and longevity of the bit. The parabolic flute design also gives these bits greater strength. They have a 135-Degree split-point design that reduces slip and walking and allows for easier no-slip starting. The bit set includes a sturdy tough case container to keep bits organized. Tough cases include a sliding soft-grip lock that keeps the case closed securely to prevent lost bits. These bits are ideal for drilling in metal, wood, and plastics.
