Triangular Shank HSS Step Cone Drill Titanium Bit Hole Cutter 1 or 4 1 3 or 8 Inch

This Triangular Shank HSS Step Cone Drill Titanium Bit Hole Cutter 1 or 4  1 3 or 8 Inch, is made from high-quality HSS steel with Titanium coating. These triangular cutters come in the following sizes 1 or 4 1 3 or 8 Inches. These are designed specifically for creating holes in the electrical, plumbing, and HVAC contractors. This is said to be the most crucial stage in electronics production. These Titanium-coated step drill bits are hard and much more resistant to heat than HSS steel. It offers superior durability that lasts up to six times longer life than high-speed steel. Used to drill metal, hardwood, and other materials at greater cutting speeds than carbon-steel bits. This step bit has the ability to drill up to 13 different size holes with a single bit. Titanium-coated step drill bits appear clean and accurate even in the toughest materials.

The unique ladder structure, a bit can open a variety of specifications of aperture. And the Anti-skid tip eliminates the need for centre punch or pilot hole drilling. Compared with the ordinary twist drill is not easy to be broken. In this drill set Deburring, chamfering, elliptic hole enlargement, twist drill, the function of them was unable, but it is possible. The titanium Coating provided reduces friction for cooler, smoother running without lubrication that allows bits to last up to 4 to 5 times longer than steel drill bits. This  HSS Steel Step Cone Drill Titanium Bit designed as  Single-fluted eliminates skidding and eases the resharpening process. This drill bit Work while water cooling thereby can effectively extend the service life of the drill bit.
