    6-Flute Spline Bit Sets

    Image of Product. Front orientation. Screwdriver Bits. 6-Flute Spline Bit Sets.
    Turn a variety of 6-flute spline screws, which are commonly found in workholding equipment. The bits in these sets have six sharply angled wings for a tight grip. Also known as Bristol bits.
    Knurled-End-Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included). Alternatively, grip the knurled shank to finger-tighten screws.
    Steel—Best for dry environments, since moisture will cause these bits to rust.
