●Battery powered or pneumatic drills?

If the task involves drilling in tight spaces, a battery-powered drill is preferable due to its maneuverability and portability. However, for high-volume production work, a pneumatic drill is a better option because of its strength and durability.

SUMAKE offers a full range of high-quality pneumatic drills, which are an excellent choice for workplaces such as the aviation maintenance industry where long-term continuous operation and the avoidance of sparks are required.

Depending on the workpieces to be constructed, drills can be divided into different shapes with different ergonomic considerations to reduce the burden on workers.
●Angle type: If the workpiece is on a flat surface or is located in a narrow space, the angle type can penetrate deeply and avoid anti-ergonomic bending of the wrist.

●Pistol type: if the workpiece is on a vertical surface, it is recommended to use a pistol-type drill to obtain the best work efficiency.

In this post, we will discuss the SUMAKE's latest angle type drill- ST-AD303 series.

●What are the advantages of ST-AD303?

ST-AD303 is a tool of the aviation maintenance industry, and its material and strength can meet relevant specifications. 

It also contains the following features:

●Stepless / Slow start speed control valve

●Durable 45°/90°/360° angle drill head

●High precision 0.3 HP motor 

●360° air exhaust

●Comfortable rubber grip

The biggest feature is that it can quickly replace head sections at different angles through a movable sliding sleeve;
At the same time, there are four models with different speeds that can share these head sections to meet the flexibility of different jobs.
