【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.

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.

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.

OEM fit, pattern is not the best
The product fits into your E46 center console perfectly. Locks in place. Great replacement for broken or worn out cup holders. The "carbon fiber" pattern leaves a lot to be desired. It was obviously dipped and the patter is skewed and very fake looking. I wrapped this with a carbon wrap and it looks fine but you might as well get a black one instead. I only gave it three stars because the fit is great as expected but the whole point of buying this one was the carbon fiber appearance which is poorly done.

Perfect Fit for 2008 Prius
I bought this for my 2008 Prius to help with allergens since I drive with my dog often. I wanted something that fit right and actually improved the air inside the car. Installation took under 5 minutes with no tools, and it dropped in without any issues. The build quality feels solid, not flimsy. After installing it, the air smells cleaner and seems to reduce dust and allergens during drives. It hasn’t restricted airflow and is holding up well with daily use so far. Pros: Fit my 2008 Prius exactly with no adjustments I noticed cleaner air and fewer allergy issues while driving Took me less than 5 minutes to install with no tools Cons: A bit more expensive than basic filters I usually get
