HSS Step Drill Bit, Double Slotted Conical Step Drill Bit (5mm-35mm) with Titanium Coating

Perfect Size: For precise drilling of various sizes from 5-35 mm in diameter, one drill bit can handle holes of different sizes.

High-Quality Material: The titanium alloy coating is made of high-quality HSS, which ensures extremely high durability and reduces friction and heat.

Titanium alloy drill bits are particularly suitable for processing thin sheets of copper and aluminum, iron plates, wood panels, plastic sheets, and other thin sheet materials. Easy to drill: The marked hole position and double flute design make drilling faster, smoother, and more precise. Laser-etched dimensions: The dimensions are laser-engraved into the metal so they won't wear down even after repeated use. Applicable materials: plastic, wood, copper, iron, fiberglass, PVC, metal fins, and aluminum (≤3mm).
