Feature

●HSS step drill 3 pieces: (4-12 mm / 4-20 mm / 4-32 mm). Made of high-quality HSS steel, and coated with titanium to reduce friction and heat. Proven performance and durability when drilling holes in plastics, wood, aluminium, copper, stainless steel and many other sheet types.
●Drill thread drill 3 pieces: (3 mm / 6 mm / 8 mm) spiral cone design prevents damage to the thread from excess drilling. Design allows for drilling, thread cutting, deburring and countersinking in wood, plastic, thin aluminium copper and other soft metals, not for hard materials.
●Easy to use: the double-edged design allows for faster and more even drilling, do not let you feel the stagnation and resistance when you use it. It has the best speed and precision.
●Laser size: the drill sizes are clearly lasered and precise drilling is easy. During the work of the step drill, pour water, can effectively extend the service life.
●Automatic impact: when the step is pressed against the surface of the object, a high impact force is automatically generated, and the adjustable cover can adjust the impact force. The surface is very non-slip and allows precise positioning without worrying about deviations.


Description

Adicase HSS Step Drill, 3 Sizes of Step Drill Bits and 3 Sizes of Twist Drill Bits for Metalworking, Woodworking, Hole Drilling

Titanium Coated Drill Bit We strive to use quality tools to improve the quality of life.

HSS step drill features (3 pieces):

1. Size: 4-12mm (length 68mm), 4-20mm (length 73mm), 4-32mm (length 101mm).

2. The step drill is used in HSS high-speed steel, the titanium alloy coating is durable.

3. Use twist drill: pre-drilling by gradual drilling, reduce damage to the drill part during drilling.

4. CNC machine tools, every process is strictly controlled and every step of quality control.

5. Compared to the twist drill, the step drill is not easy to break and can cut different sized holes.

Countersunk Tap Features (3 pcs):

1. Size: 3 mm (length 60 mm), 6 mm (length 86 mm), 8 mm (length 93 mm).

2. High hardness, rust-proof, solid and durable.

3. Suitable for drilling, tapping, cutting on soft metal, aluminum plate, etc.

4. Self-centering point, do not need assisted center drilling or center punching.

5. Drilling and tapping in one, one-step processing, save significant processing steps and time costs, improve work efficiency.

6. When drilling a hole, you should inject water at the same time to cool the drill. This will help you increase the value of the drills. If you cannot cool the drill when drilling holes, the drilling speed should not be too high and you should not drill holes too frequently.

Two flutes design:

The chip removal capacity is better and the drilling speed is accelerated. Improve your productivity.

DIY or general construction:

Heat treated high gloss polished drill perfectly round holes in wood, steel, brass, plastic etc.

For cutting holes in materials:

Such as stainless steel, wood, thin iron/copper, aluminum, PVC, wood, plastic, etc.

Clean and precise:

The holes are very advantageous that you only need this one drill for different drill hole sizes.

Please note:

▶ When using the drill, it is better to offer some lubricating oil or cooling oil.

▶ If you have any problems with our products, please contact us. We will do our best to help you solve the problems as soon as possible.
