[pdf] These precision ground, bright finish bits are constructed out of hardened and tempered M2 high-speed steel and fall between standard fractional drill sizes. These jobber length bits feature a 135-degree split point for fast penetration and accurate self centering.
[pdf] These drill bits are specifically engineered to enhance cutting power and debris removal, ideal for drilling through harder rock types like sandstone and limestone. Their triangular shape concentrates the cutting force, effectively penetrating tough layers.
