【ABOUT THIS ITEM】

【9 Step Sizes】Spiral flute design, featuring 9 distinct steps from 4 to 20 mm, offers seamless and effective drilling across various thicknesses, eliminating the need for multiple bits. Includes 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm.

【AlTiN Coating】Step bits coated with aluminium titanium nitride, rated at 89HRC for exceptional hardness and thermal properties. This coating offers superior resistance to heat, wear, and corrosion, with high adhesion and low friction. Laboratory tests show it more durable than steamed black oxide coating for longer bit life.

【C-Profile Design】EZARC Step Drill Bits feature a triple-flute design for enhanced stability, effectively addressing issues of deviation during the cutting process. Additionally, 'C-profile' cutting edge ensure smoother cutting and 2X increase in cutting speed.


 

【M35 HSS Step Drill】M35 cobalt high-speed steel achieves high levels of hardness and wear resistance through appropriate heat treatment. Its toughness and bending strength surpass those of standard high-speed steel, making this step drill bit more suitable for cutting harder materials, such as mild steel, medium hardness steel, stainless steel.

【Please Note】Follow these tips to keep your drill in top condition: add cutting oil or spray water to cool during continuous use, the start-up speed will be slower due to the larger cutting angle, any quality problems, please feel free to contact us.

 

【Tips】

1.How will AlTiN coating affect the performance of step drills?

AlTiN Coating, with a hardness of 89 HRC, offers excellent hardness and thermal properties. It provides great resistance to heat, wear, corrosion and can withstand temperatures up to 900°C.

2.What types of metal can I cut with ezarc step drill bit?

You can use EZARC step drills to cut or drill through various metals, including aluminium, brass, copper, cast iron, galvanised pipe, stainless steel, and low-carbon steel.

3.How do I properly use this step drill bit?

Ensure the chuck is securely tightened on the power tool. Use low speed and apply light pressure on the workpiece until reaching the desired depth. Lubricate the cutting edge with oil or a water-soluble lubricant to reduce friction, heat, and debris.

4.Are there any requirements for the thickness of the materials used?

The thickness of metal plates should not exceed 3mm, and the thickness of stainless steel plates should not exceed 1mm.

Some parts don't fit the vacuum or are funky (in a bad way)
Overall it's nice to have these replacement parts. A few issues: 1. The included tiny plastic-handled screwdriver snapped in half right away when we used it to remove some screws from the unit. 2. The screwdriver isn't the right size for some of the screws. It would be nice to have 2 sizes, both sturdier than the original. 3. The cleaning tool (see pic) has a square shaped end, instead if a tapered end like the original. This means you can't use it to clean the end notches on the main brush. 4. One of the main brushes doesn't fit well, and causes a horrendously loud noise when we tried it. The second brush is as quiet as the original.

Very poor quality items. Rotating brushes are cheap, used with inferior adhesive as they come out very easily. The roller seems used and cleaned to resell as it does a poor job. With all the items included it seems like a good deal, but the poor quality makes it not so. Do not recommend. I bought the items in late December 2022 and I just put my last rotating brush on already (Late March 2023).
