Reamers for Dowel-Pin Holes
Finish holes to match standard fractional dowel pin sizes. These reamers are undersized with a very slight taper to ensure dowel pins fit snugly when installed.
Round Shank
 |
Straight Flute |
These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.
Straight Flute—The most common flute style, these reamers are suitable for a wide range of applications, but not recommended for holes with a keyway or other breaks in the surface.
Carbide—For the highest level of accuracy when cutting hard materials, these are our hardest, strongest, and most wear-resistant reamers. They're used on materials such as iron, hardened steel, steel alloys, and plastic. Their hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the reamer from breaking.
