These jobbers'-length bits have the rigidity and length required for most applications. They are designed to make clean holes in abrasive material. Their point keeps the bit centered without a pilot hole.

Uncoated drill bits have three drill points that make clean holes in fiber-reinforced composites without fraying or delaminating the material.

Diamond-coated drill bits are highly wear resistant for drilling in abrasive material. They last longer than uncoated bits.

Harder, stronger, and more wear resistant than cobalt steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. All are titanium nitride (TiN) coated for longer life and higher drilling speeds. They are short length, also known as screw machine and stub length, which provides maximum rigidity for drilling straighter holes than standard-length drill bits. The split point keeps the bit centered without a pilot hole.
