The used HSS Co shell reamer set is a high-precision tool designed for finishing holes, particularly suitable for machining operations requiring the utmost accuracy. This specific set includes various reamer sizes ranging from 19 mm to 60 mm in diameter, with reamers in the following sizes: d.40, d.26, d.29, d.23, d.19, d.20, d.22, d.30, d.35, d.48, d.55, d.47, d.45, d.52, d.38, d.60, d.50, and many more. The various sized reamers make this set versatile and suitable for a variety of industrial applications.

Main components and materials:

The set is made of HSS Co (high-speed steel with cobalt), a heat-resistant and highly hard alloy that provides the tools with superior durability even under thermal and mechanical stress. This makes the reamers ideal for working on difficult materials, such as stainless steel, titanium, and other hard metal alloys.

Measurements and technical details:

• Reamer diameters: 19mm to 60mm .
• Material: HSS Co (High Speed ​​Steel with Cobalt).
• Type: Sleeve reamers , designed for use with standard shanks and to be easily replaceable.

Mechanical characteristics:

Shell reamers are primarily used for finishing and calibrating pre-drilled holes. Thanks to their spiral or straight design, these tools can remove small amounts of material, ensuring an extremely precise finish and close tolerances on the hole diameter.

Usage procedure:

To properly use a reamer from the HSS Co. shell reamer set , you need to choose the correct reamer based on the desired hole diameter. The reamer is mounted on a machine tool, such as a drill or milling machine, and inserted into the existing hole. The rotational movement and controlled feed of the tool ensure a precise hole finish, keeping vibration and friction to a minimum.

Matching accessories:

Shell reamers can be combined with standard chucks and tool holders, as well as automatic lubrication devices to improve machining quality and reduce tool wear. Specialized coolants can also be used to reduce temperatures when machining high-strength materials.

Mathematical formulas for optimal parameters:

Calculating optimal operating parameters, such as cutting speed (Vc) and feed rate (f), is based on the workpiece material and the reamer's properties. A typical formula for cutting speed in reaming is:

$$V$$

Where:

• VcVc $V$ $c$ is the cutting speed in m/min;
• DD $D$ is the diameter of the reamer in mm;
• NN $N$ is the number of revolutions per minute (rpm) of the machine tool.

Maintenance:

To ensure the longest life of your Co HSS shell reamer set , regular maintenance is essential. After each use, the tools should be thoroughly cleaned to remove metal shavings and protected with oil to prevent rust. Reamers should be replaced or sharpened when you notice a reduction in finish quality or increased friction.

How to understand if it is a good used item:

Purchasing a set of used HSS Co reamers can be an excellent choice if the tools have been properly maintained. Before purchasing, it's important to check for signs of excessive wear, such as chipping or corrosion. If the cutting surfaces are still sharp and free of defects, the set can continue to provide high performance.

Sectors of use:

The HSS Co. shell reamers set is used in a variety of industries, including mechanical engineering , automotive manufacturing, aerospace , and heavy machinery construction . Precision reamers like these are essential for ensuring perfect hole sizing and finishing in high-precision mechanical components.

Why it's better to buy it used:

Buying a used reamer set is advantageous because it allows you to get high-quality tools at a reduced price. Since HSS Co are known for their durability, a well-maintained set can offer performance comparable to a new one, at a fraction of the cost.
