The Impact Drill is generally used in professional applications. It is a device for mounting on impact drills. It is used for drilling concrete foundations, walls, brick walls and granites to install expansion bolts and plastics in the holes. Expansion pipe and other fasteners. Most people do not understand the impact Drill Bit well. The following Xiaobian will tell you how to install the impact drill bit. Difference between impact drill and Twist Drill.

How to install the impact drill?

First remove the drill: Place the impact drill on the ground (the drill bit is up), hold down the plastic ring at the bottom of the drill bit with your left hand, lift the drill bit with your right hand, and remove the drill bit by turning it around.

Finally install the drill: or inverted impact drill, hold down the plastic ring with your left hand, and rotate the right hand with the drill.

Difference between impact drill and twist drill

1, impact drill

Impact drills work by rotation and impact. The single impact is very slight, but more than 40,000 impacts per minute can produce continuous forces. Can be used for natural stone or concrete. When the impact drill is working, there are adjustment knobs at the drill chuck, which can be adjusted in two ways: ordinary hand drill and impact drill. However, the impact drill uses the gears on the inner shaft to perform the impact effect, but the impact force is far less than that of the electric hammer. It is not suitable for drilling reinforced concrete.

2, twist drill

A twist drill is a Tool that cuts a round hole of a workpiece by rotary cutting of its relatively fixed axis. It is named after its flute shaped like a spiral. Spiral slots have 2 slots, 3 slots or more, but 2 slots are the most common. Twist drills can be used in manual, electric hand-held drilling tools or drills, milling machines, lathes and even machining centers. The bit material is generally a high speed tool steel or a hard alloy.

3, What is the difference between twist drill and impact drill?

The impact drill is modified on the basis of the twist drill to make it suitable for a variety of operational requirements, the shape can be understood in this way, the twist drill is a simple handle + spiral, the impact drill mostly handle + spiral + flat head.

The above is how Xiaobian introduced the impact drill bit how to install? The difference between the impact drill bit and the Twist Drill Bit, we should have some understanding of the impact drill bit after watching it. In the course of future use, we must also pay more attention to the safe operation and avoid unnecessary damage.
