【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.

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.

Gets the job done, not sure for how long
Color: Rustic Wood
These were hard to assemble due to the screw needing to go behind a metal bar, meaning all of my shelves are wobbly and one is starting the cave in the corner some. Overall not too bad for the price (got it on sale, wouldn’t recommend paying full price. Also didn’t realize the wood was unfinished so it’s splintery (be careful, I got several splinters when assembling and putting up).

A great $30
Color: Grey, Color: Grey
The wood is cheap particle board (probably better bc they are very light weight) but the brackets are plenty strong and sturdy. Advice on the install: your walls may not be exactly 90 degrees. Install one bracket after the other is holding the shelf up. Super pretty.

Great shelves but be warned.
Color: Grey
These shelves are great for small items and can definitely hold up to their advertised weight if mounted in a stud. However, DO NOT use the longest screws at all. All the screws are low quality and are likely to break. The medium length ones are sufficient for everything. If your wall faces an exterior concrete wall: break off the tips on the dry wall anchors, they are too long.

These are a great corner option
Color: Rustic Wood
Was looking for something to set in some corners, and these fit the bill greatly. They are nice looking and easy to assemble and then put up. They hold a plant and some rock items nicely. A good purchase.
