The Alvord Polk 651-0 straight flute repairman s reamer is a brace shank tool made of high-speed steel with no finish or coating, and is most commonly chosen for deburring a drilled hole. Repairmen s reamers can also be used to countersink a hole.
Straight flute reamers are useful for uninterrupted cuts in general purpose applications. These reamers make small, circular, and precise enlargements to through and blind holes. High-speed steel is a general purpose steel for cutting tools and is compatible with many metalworking materials. It is often lower in price than other cutting tool materials.
For reamers in the 651-0 series with 1/8 inches point diameter and 1/2 inches large end diameter there are six flutes, and for those with 3/8 inches point diameter and 1 inch large end diameter there are eight flutes.
Reamers are used to finish existing holes. When holes are created using common applications like drilling or punching they often have minute imperfections. Their roundness may be flawed, or their diameter may be slightly smaller than required. Reamers are made to exacting tolerances, so they can correct such errors and create precisely round holes of exacting dimensions. Reaming is often used before tapping screw threads.
Alvord Polk manufactures a broad family of cutting tools, brushes, and tooling components, following ISO 9001 standards for quality and environmental impact of their products. Their offices and manufacturing facilities have been located in the United States since 1881.
