13PCS DIN338 fully ground HSS Co M35 twist drill bits set

1.The drill bit is made of high speed steel (HSS) containing cobalt (Co) and M35 grades, which have higher hardness and heat resistance and are suitable for demanding drilling applications in materials such as stainless steel, alloy steel and other hard materials.

2.FULLY GROUND: Drill bits are fully ground to ensure precise dimensions, smooth surfaces and consistent performance for accurate, clean drilling.

3.135-Degree Split Point: Drills may feature a 135-degree split point design that improves drilling performance by reducing the need for pilot holes, minimizing travel, and promoting efficient chip evacuation.

4.Titanium Coating: Some kits may come with a titanium coating, which further increases the drill's hardness, reduces friction and enhances heat resistance, extending durability and improving performance.

5.Wide Size Range: This kit includes a variety of drill bit sizes, providing the versatility to drill different hole sizes and adapt to a variety of applications and materials.

6. The kit may come with a storage case or organizer to safely store drill bits, prevent loss and damage, and provide easy access and organization.
