To ensure the of a project it's important that the product is completed to a high standard of finish. Part of this can be when producing holes through materials, sometimes the material is leftover and a hand reamer can ensure the hole is left completely smooth. Hand reamers like machine reamers are designed to smooth over a hole with great precision and quality.
When drilling a hole it can leave the hole uneven, and reaming will slightly enlarge the hole. Producing a smaller hole initially will allow reaming space, called the allowance. Its recommended that the drilled diameter shouldn't be enlarged more than 5%.
Hand reamers are typically made from carbide or high-speed steel (HSS), these multi-edged rotary cutting tools are used within metalworking industries for enlarging and finishing holes with a high level of precision and accuracy.
At RS Components, we have both machine reamer bits and hand reamer bits. The main difference between the two is that hand reamer bits have a longer taper or lead in at the front end of the bit, which compensates for the difficulty of using hand power alone.
