5. Titanium alloy coating reduces friction and they are more durable than uncoated drill bits.HSS(High speed steel) has a longer service life.

Superior Quality

Titanium coating ensures excellent durability and sharpness, which reduces friction and reduces operating temperature.

Using the classic high speed steel structure, it has longer service life, ensures easy cutting of stainless steel plate, aluminum plate, copper, plastic and wood plate, as well as many other types of sheet metal, and can automatically deburring when drilling to keep the drill bit a little clean.

Quick and Clean

135 degree bifurcated tip improves cutting speed and is smoother.

Prevent slipping in the operation, and make accurate holes for you.

As the size of the next step increases sharply, the cutting edge can automatically deburring the holes left by other drills, so that the cutting edge can scrape the burr off the entry surface of the workpiece. Save your time and energy.

Positioning Aid

Each bit has a corresponding digital size, which can provide accurate positioning assistance.

Numerical control laser engraving is adopted to make the mark clear, and it will not fade with long time use.

And it is non-contact processing, which will not cause mechanical extrusion or mechanical stress to the material. No "knife mark", no damage to the surface of the workpiece; no deformation of the material.

Convenient Storage

Made of 600D Oxford cloth, it has the characteristics of thick, good elasticity, strong firmness, soft luster, waterproof and durability.

The storage bag is designed according to the size of the ladder drill, which does not take up space.

The design has three lattices, three ladder drills together to store, each time you use it, you don't have to worry about not finding one of them.

INSTRUCTIONS for USE

⓵ Use other tools to measure the diameter of the required hole size.

⓶ Then select the corresponding size of the ladder drill to confirm which is the corresponding size.

⓷ Install the step drill correctly on the electric drill, and finally aim at the position of the target hole, which is perpendicular to the workpiece, and then start drilling to the required size.

NOTE

• During the operation, water must be injected to cool the drill bit. During the operation, the high temperature smoke is easy to be annealed, so as to avoid reducing the service life of the drill bit.

• When in use, the metal thickness must not exceed 3 mm.

• When the new bit is running in the hole with low axial pressure and low rotation speed for 20-30 minutes, it should be gradually increased to normal axial pressure.

• When drilling a new hole with a new drill bit, it is necessary to remove the debris (rocks, scrap metals, etc.) around the hole. At the same time of rotation, ventilate slowly and close to the surface to prevent the bit from being knocked down and damaged by impact.

• When the drilling tool is in the hole, reverse rotation is strictly prohibited to prevent the bit from falling into the well.

• When the drill bit is in the hole and the air compressor stops working suddenly, rock slag is very easy to enter the drill bit. Therefore, it is strictly forbidden to rotate for a long time, resulting in bearing wear, rock slag repeated crushing (or sticking), and bit wear is accelerated.

Electrical Installation and Maintenance Are you still bothered by the fact that the hole is too small to be drilled with other suitable bits? never mind, There are ladder drill, a variety of sizes can be smoothly reamed for you, to your satisfaction size.
