While both tools are used for creating holes, a reamer is designed for enlarging and finishing an existing hole to a precise size and smooth finish, while a drill is used to create the initial hole. Reamers provide a higher degree of precision and are used for fine-tuning hole dimensions and surface quality.

Reamers can be used on a variety of materials, including metal, concrete, wood, and plastic, depending on the type of reamer and its material. However, harder materials, such as hardened steel or rock, require reamers made from stronger materials like carbide or cobalt steel.

The right reamer depends on the material you are working with, the size and type of hole you need to finish, and the required tolerance. For example, carbide reamers are best for hard materials, while HSS reamers are suitable for general-purpose tasks. Consult a manufacturer or supplier to ensure you select the appropriate reamer for your needs.

Regular cleaning, inspection for wear, and proper lubrication are key to maintaining reamers. After each use, clean the reamer to remove debris, inspect for signs of wear or damage, and store it in a protective case to prevent damage.

Yes, reamers can be sharpened if they become dull over time. However, sharpening should be done carefully to avoid damaging the tool. It's important to follow manufacturer guidelines for sharpening or have the reamer professionally serviced.

The lifespan of a reamer depends on the material being worked on, the frequency of use, and the quality of the tool. High-quality reamers made from carbide or cobalt steel tend to last longer than HSS reamers, especially in tough drilling conditions.

Yes, reamers are available in a wide range of sizes and can be used for both small and large holes. For larger holes, specialized reamers such as shell reamers or boring reamers may be used.
