Made of No. 45 steel, the drill frame and hand-operated plate are cast using precision silicone melt technology;

2. Thickened high-strength ABS engineering plastic handle, the handle is hollow and can store spare drill chucks;

3. The gears are precision cast by powder metallurgy technology, with high precision, hardened by quenching and wear-resistant;

4. Double gear drive mechanism, flexible hand operation and not easy to get stuck;

5. It adopts a key drill chuck that is common to ordinary electric hand drills, with high clamping accuracy, and the drill bit is not prone to breakage due to eccentricity;

The product does not require any power drive. The hand controls the rotation speed and drilling position. It is easier to control and safer than an electric drill. However, the rotation speed is low, the efficiency is low, and the transmission torque is small. Therefore,

Not suitable for drilling hard metal materials, ceramic tiles, masonry, concrete, etc.;

Suitable for wood, bamboo, soft iron, copper, aluminum, plastic, PVC, acrylic, fiberglass board, circuit board, etc.

It is an ideal hand tool for woodworkers, DIY enthusiasts, model enthusiasts, students' hands-on ability testing, teaching practice, etc.
