High Speed Steel – Suitable for workpieces with a hardness of less than 25 on the hardness scale, such as carbon steel, sheet iron, insulation boards, PVC boards, planks, and wood with a thickness less than 5mm.
Its titanium coating ensures that this step drill set is resistant to heat, corrosion, and rust. It also provides excellent rust resistance.
Good Design – The triangle shank fits securely into power tools chucks and prevents slippage; the two-flute design clears chips more quickly and allows particles to escape more easily from the chuck.
It has the ability to automatically deburr holes while drilling, allowing the drill bit to remain clean.
A must-have for any family member, handyman, or professional . Perfect for small home repairs and light jobs such as drilling holes in plastic, aluminum, copper, and a variety of other types of sheet metal, this drill is lightweight and portable.
