The LTF model SB-25 column drill is a versatile and robust machine, designed for drilling on different materials, with precision and reliability. As a used machine, the SB-25 model retains many of its original mechanical qualities, such as the solidity of the cast iron structure and the efficiency of the engine. Its compact size and ease of use make it suitable for both small workshops and industrial contexts.

Components and Measurements

The LTF SB-25 drill press is equipped with:

• High quality steel column, which ensures stability during work.
• Work table adjustable in both height and inclination to allow variable drilling angles.
• Chuck with a drilling capacity of up to 25 mm in diameter.
• Three-phase motor, compatible with 380V voltage.
• Wide spindle stroke, ideal for deep drilling.

Mechanical characteristics

The 0.75-1 kW motor provides enough power to process materials such as metal, wood and plastic. The spindle rotation speed can be adjusted on multiple levels, allowing optimal customization depending on the material being processed.

Usage procedure

Using the drill is simple: after mounting the piece on the table, you adjust the height of the table and choose the appropriate spindle speed. Then start the motor, using the lever to lower the spindle until the piece is drilled. The model is equipped with a safety guard around the chuck to avoid accidents.

Matching accessories

Various accessories are available such as clamping vice, additional chucks for different hole sizes and lubrication equipment, useful for working on hard metals.

Formulas for optimal use parameters

To optimize the use of the drill, it is possible to apply the cutting speed formula V=πD⋅N1000V = \frac{πD \cdot N}{1000} $V$ $=$ 1000 π D ⋅ N ​, DD $D$ is the diameter of the hole and NN $N$ is the speed in revolutions per minute (RPM). This helps adjust the speed based on the material being processed.

Workable materials

The LTF SB-25 drill press can work effectively on wood, metal and plastic, but with proper speed adjustments and the use of appropriate lubricants, it can handle even harder steels.

Maintenance

Good maintenance of your used drill press includes regular lubrication of the chuck, cleaning of the mechanical parts and checking that the motor and belts are functioning correctly. Replacing any worn parts will ensure a longer useful life and constant performance.

How to evaluate a good used one

When purchasing a used drill like the LTF SB-25, checking the stability of the column, the condition of the belts and the accuracy of the chuck is essential. Make sure that the motor runs without abnormal noise and that the table and spindle adjustments are smooth.

Sectors of use

The LTF SB-25 is widely used in carpentry, mechanical workshops and craft workshops thanks to its flexibility and ability to process a wide range of materials. It is often better to buy it used because it offers an excellent quality-price ratio, guaranteeing performance that is still valid even after years of use, especially if well maintained.
