Why use a reamer bit At some point it may be necessary to increase the size of a pre-drilled hole to a larger diameter or to drill large diameter holes. Reamer Bits are designed specifically for this purpose. Reamer Bits are custom manufactured in a wide range of styles to meet field requirements. A custom reamer bit is an effective way of enlarging holes. The Reamer Bit Advantage 1). Straighter Holes By drilling a smaller hole with a "pilot" bit, then attaching that said bit onto the bottom of the reamer bit. The reamer bit will follow the path of the hole drilled by the smaller bit. 2). Larger holes with smaller rigs By drilling a hole stages, large holes can be drilled with smaller rigs. A smaller hole requires less power. 3). Replacing Cutters and Lower Cutting Cost
On most reamer bits designs, the cutters can be easily replaced. The cost to replace a cutter is a fraction of the cost to replace a large tricone rock bit 4). Cost of large rock bits will be higher Large diameter rock bits not only cost a lot, they can be difficult to find. A more economic solution is to use a reamer bit that uses smaller tricone rock bits segments. 5). Flexability Reamer bits can be fabricated in just about any size, and can be configured to drill through any formation
